Habitat Aspect Climate:

Pseudanthus orientalis prefers full sun to dappled shade. It usually grows in open situations on coastal dunes, coastal heaths or at times on granitic heaths. The altitude ranges from 2 meters ASL to 950 meters ASL.

The temperatures range from minus 4 degree in July to 39 degrees in January.

The rainfall ranges from lows of 500mm to 2000mm average per annum.

Soil Requirements:

Pseudanthus orientalis prefers to grow on coarse sands, fine sands or light fatty clays often with copious quantities of forest litter. The soils are usually derived from accumulated peaty beach sands or at times decomposed granites. The soils pH ranges from 5.5pH to 6.5pH. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated as are salt laden winds.

Height & Spread:

Wild Plants:0.2m to 0.3m by 0.4m to 0.6m.

Characteristics:

Pseudanthus orientalis grows as a small rigid shrub with decumbent angular stems. The older stems are grey-brown with chartacea like wings on the angles while the younger stems and new growth are yellowish-brown and glabrous.

The opposite or alternate leaves are often crowded along the apexes of the stems becoming more disjunct as the stems mature. The sessile, oblong-linear to linear-spathulate measure 4mm to 10mm in length by 1mm to 1.5mm in width. The bases are rounded while the apexes are obtuse. The concolourous or discolourous laminas are deep grass-green, glabrous and semi glossy on the upper laminas while the lower laminas are paler. The laminas are concave on the upper surface and decurve downwards near the apexes while the margins are entire. The mid vein is faintly prominent on the lower lamina while the pinnate lateral veins are at 90 degrees and are slightly prominent on the upper lamina.

Inflorescences are born singularly from the leaf axils. The pale yellow flowers are dioecious.

The male flowers are on short pedicels that measure 1mm to 3mm in length. The bright yellow stamens are crowded in the center with the inner stamens slightly longer than the outer stamens. The stamens measure 1.5mm to 2.2mm in length.

The female flowers are sessile. The perianth segments measure 1.5mm to 2mm in length and are often slightly reddish. The flowers appear from January early April.

The fruits are obloidal capsules. The glossy capsules are mid brown, glabrous and measure 4mm to 5mm in length. The green capsules turn pale grey-brown when ripe and contain a single black seed when ripe.

Wildlife:

Pseudanthus orientalis’s wildlife is unknown to the author.

Cultivation:

Pseudanthus orientalis is an interesting small sub shrub. It is classified as a weed by most gardeners. In cultivation they will grow from 0.2 meters to 0.4 meters in height by 0.4 meters to 0.8 meters in diameter.

It grows exceptionally well on lighter soils where deep leaf litter keeps the soil cool and moisture at an even level. If these requirements are met they can cope with temperatures as low as minus 4 degrees and up to 42 degrees. It is moderately drought tolerant in most districts that receive over 500mm of rainfall a year.

Propagation:

Seeds: The seeds can be removed easily from the fruits that have fallen to the ground.

Sow freshly treated seeds directly into a seed raising mix, keeping them moist not wet. When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position.

Confusing Subspecie Varieties:

Pseudanthus pauciflorus subsp. pauciflorus stems are glabrous.

Pseudanthus pauciflorus subsp. arenicola stems are floccose.

Wildlife:

Pseudanthus pauciflorus’s do not appear to have any predators.

Cultivation:

Pseudanthus pauciflorus is an interesting small sub shrub that should be more widely grown in subtropical to cool temperate gardens. It is ideal in rockeries or against north and west facing walls. In cultivation it will grow from 0.2 meters to 0.4 meters in height by 0.4 meters to 0.8 meters in diameter.

Pseudanthus pauciflorus would make outstanding contribution to a moist heath gardens especially where it is mass planted. Here it can be used adjacent to the smaller growing plants scattered throughout the heath scene in small groups. When you design a flat heath garden which this Proiphys is well suited don’t use contours to display the plants as heath lands are almost always flat or have a slight rise. Plants must be planted close together and be short so you can see over the tallest ones with the exception of one or two plants at the most. These will be feature plants. The idea is to achieve a feeling of expansive flatness. This can be achieved with using the Pseudanthus pauciflorus’s grass-green leaves and having them contrasting with finer or larger deep green, soft grey to glaucous coloured foliages. Make sure it is kept in small areas devoid of plants that will over grow them and that they will have plenty of sun shine. Use a lot of procumbent plants like Lechenaultia biloba or Lechenaultia formosa which would look stunning in flower together. Mix them with other smaller shrubs so none of them dominate the scene but blend in to give a mosaic of foliage colours that you oversee. For taller shrubs and annuals I immediately think of Actinotis helianthi, Dianella atrax, Dianella caerulea or Pattersonia specie for two great contrasting foliages.

It is ideal in settings near ponds in court yards or the rockery. It needs full sun to grow at their best. Place them near old stumps and roots or medium size rocks to make the stumps, rocks or roots look larger and more gnarled. The deep greys and blacks against the large ovate leaves and stems will contrast both the finesse of the plants and the coarseness of the stumps, rocks or roots. Select an area of ground and let your hair down and be imaginative. Sparingly use other plants when planting and remember that this plants foliage and form is the center of attraction. Planted in mass using a gentle slope or a basin with a small to medium pool at the bottom would also give a strong contrast for most of the year. A billabong affect would give a quite tranquil affect where as a waterfall or cascades would give more stimulation and energy to the scene. When using this plant as a feature only grow small plants that do not reach more than 150mm in height and have a compact habit with either blue or grey leaves, but be careful that these plants do not steal the stage. Taller plants can be grown in the background for balance. Annuals and perennials would really compliment the scene especially during the winter when the leaves are not present.

Propagation:

Seeds: The seeds can be removed easily from the mature fruits that have fallen to the ground.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position.

Cuttings: Fortunately cuttings should be easy to strike. Use 100mm to 200mm long tip cuttings or lateral shoots from the present season’s growth. Take them in warmer months of the year. Remove half the leaves from the bottom section being careful not to tear the bark.

1 Prepare the cutting mix by adding two thirds sharp clean river sand, one third peat or one third perlite. These ingredients must be sterilized,

2 Select good material from non diseased plants,

3 Select semi green stems for cuttings. Look for a stem with two or three nodes,

4 Place the cutting on a flat, hard surface, and make a clean cut down one side of the cutting at the base for 10mm with a sharp sterile knife or razor blade. – This scarification of the node will increase the chances of roots emerging from this spot. Now remove all but one or two the leaves, leaving the apex leaves in tact. If the leaves are very large in proportion to the stem, cut off the apical halves.

5 Hormones are not required,

6 Use a small dipple stick or old pencil to poke a hole into the soilless potting mix. Ensure the hole is slightly larger than the stem diameter and be careful not to wipe the rooting hormone off the cuttings base. Place 2 to 4 cuttings in each of the 50mm native tubes,

7 I like to place the tubes in bucket with holes drilled in the bottom to allow excess water to drain out. A plastic bag that fits over the bucket is ideal to help maintain temperature and moisture. Place in a semi shaded, warm position like under 50{98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} shade cloth.

8 When the cuttings have struck, open the bag to allow air circulation for a few days to a week,

9 Once hardened off remove the cuttings from the bag and allow to further hardening for a few more days to a week,

10 Transplant into a good potting mix to grow on.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September or March to maintain health, vitality and better flowering.

https://avh.ala.org.au/occurrences/search?taxa=Pseudoraphis+paradoxa#tab_mapView

Habitat Aspect Climate:

Pseudoraphis paradoxa prefers full sun light to dappled shade to full sun. It grows in and around ephemeral pools or permanent pools and slow moving watercourses, backwashes and stream meanders often forming floating mats close to the banks or a dense turf on drying mud. The altitude ranges from 2 meters ASL to 750 meters ASL.

The temperatures range from minus 3 degree in August to 36 degrees in January.

The rainfalls range from lows of 550mm to an average of 2000mm.

Soil Requirements:

Pseudoraphis paradoxa prefers better quality gravelly loams and light silts to heavy silts or wet and seasonal mud. The soils are deep or close to permanent water. The soils are derived from alluvial deposits or at times wet podzolic depressions. The soils pH ranges from 4.5pH to 6pH. It tolerates water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 0.2m to 0.5m by 0.5m to 1m.

Characteristics:

Pseudoraphis paradoxa grows as a short, spreading perennial grass which is semi aquatic or fully emergent. The stolons are present as are the prostrate culms. The mid culm nodes are
glabrous. The ligule is an eciliate membrane, a fringed membrane or a ciliolate membrane. The ligules measure 0.8mm to 1.5mm in length.

The alternate, linear leaves measure 10mm to 80mm in length by 2mm to 6mm in width. The bases taper to the sheath while the apexes are acute. The concolourous laminas are grass-green to blue-green, dull and smooth to scaberulous. The laminas are flat while the margins are entire. The mid vein and parallel lateral veins are slightly prominent on the lower lamina and are visible on the upper lamina.

The inflorescence are semi dense, cylindrical, panicles born from the terminals of a culm. The panicles measure 30mm to 85mm in length by 6mm to 14mm in diameter by 6mm to 14mm in diameter while the racemes measure 10mm to 15mm in length.

The spikelets are sessile. There are 1 or 2 fertile spikelets on each raceme with the lowest floret being sterile without rachilla extension. The rachilla internodes are elongated below the proximal fertile floret. The lanceolate dorsally compressed spikelets measure 7.5mm to 11mm in length. The slender pedicels are glabrous and disarticulating above the glumes.

The glumes are dissimilar and are thinner than the fertile lemmas. The lower and upper glumes surfaces are smooth to asperulous. The lower glume is oblate, hyaline, without keels and are nerveless. The upper glume measures 5.5mm to 8.5mm in length. The upper glume is elliptic, membranous, without keels and have 13 to 19 faint nerves. The upper glume measures 7.5mm to 11mm in length.

The 2 sterile basal florets are barren without a significant palea. The basal sterile floret is a male which has a palea. The lemma of the lower sterile floret measures 100 {98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} of the length of the spikelet. It is membranous with 13 to19 faint nerves. The fertile florets are female. The fertile lemmas are without keels and have 5 nerves and measure 3.3mm to 3.7mm in length. The palea are without keels.

The 3 stamens measure 1.4mm to 2mm in length. The flowers appear from late November to early March.

The fruits are depressed to concaved obloidal to ellipsoidal grains. The grains measure 2mm to 2.5mm in length by 1.5mm to 2mm in diameter. The pale green grains turn pastel fawnish-yellow when ripe.

Wildlife:

Pseudoraphis paradoxa is the host plant for the Little Native Mouse, Pseudomys delicatulus and probably most other native mice and rats. It is also probably a stable food source for many small Parrots, Rosellas. The Double Bar Finch, Taeniopygia bichenovii and the Red Browed Finch, Neochmia temporalis have been seen eating the seeds.

The leaves and stems are a source of food for the Swamp Wallaby, Wallabia bicolor and a stand by food source for the Red Neck Wallaby, Macropus parryi in times of drought.

Cultivation:

Pseudoraphis paradoxa is a large spreading grass for large gardens around the edges of dams or along slow moving water courses where its culms can spread out over the water’s surface. It can be slashed and will recover very quickly but is not suitable for long term heavy grazing.

It is ideally suitable for full sun areas in low depressions where water lies for extended periods in ephemeral pools or the ground remains wet throughout the year.

It is a preferred food source of grazing stock but has the disadvantage of coursing heavy erosion around dams and along creeks and streams due to heavy traffic when foraging the grass. It is a poor to moderate soil stabilizer.

Propagation:

Seeds: Sow the seeds directly into a seed raising mix. Cover them with 2mm of fine sand and keep moist not wet or scatter in the area you wish to cover.

Place the tray in a warm sunny position. When the seedlings are 25mm to 50mm tall, prick them out in small groups and plant them into 20mm tubes using a good organic mix.

Once the seedlings reach 75mm to 80mm in height, plant them out into their permanent position and water thoroughly with our recommended fertilizer. Plant them at 500mm centers.

Alternatively the seed can be broadcast out in small areas or used in a seeder on broad acreage.

Fertilize using organic chicken pellets at the time of sowing.

Unranked: Monocots

Order: Asparagales

Family: Orcidaceae

Subfamily: Vanilloideae

Tribe: Vanilleae

Specie: From Folium, which is Latin for foliage. It refers to plants, which are rather leafy or te leaves are scarce.

Sub specie:

Common Name: Great Climbing Orchid.

Distribution:

Pseudovanilla foliata is found south from Cooktown in far northern coastal Queensland to South Brother and the John’s River in central coastal New South Wales. It is mainly found on the eastern side of the Great Dividing Range to the coast.

https://avh.ala.org.au/occurrences/search?taxa=Pseudovanilla+foliata#tab_mapView

Habitat Aspect Climate:

Pseudovanilla foliata prefers medium shade to dappled shade. It grows in well developed, moist lowland, moist upland rainforest moist sclerophyll forests especially in sheltered southerly slopes. It is somewhat saprophytic in nature, deriving some or most of its nourishment from rotting wood in old stumps and logs. Its altitude ranges from 10 meters ASL to 700 meters ASL.

The temperatures range from minus 5 degrees in August to 38 degrees in January.

The rainfall ranges from lows of 500mm to 2000mm average per annum. The plants are more reliant on capillary action from nearby permanent water sources to keep the soils permanently moist.

Soil Requirements:

Pseudovanilla foliata grows as a terrestrial orchid on coarse sands, fine sands and sandy loams to light gritty fatty clays. The soils are derived from decomposed granites, sandstones and accumulated peaty beach sands. The soils pH ranges from 4.5pH to 6pH. It does not tolerate water logged soils however soil moisture is essential for survival throughout the year. Non saline soils to slightly saline soils are tolerated.

Height & Spread:

Wild Plants: 8m to 15m by 0.15m to 0.4m.

Characteristics:

Pseudovanilla foliata grows as a slender erect vine not exceeding a stem diameter of 20mm in diameter. It climbs by means of adventitious roots produced at the nodes. The stems are yellowish green and contain chlorophyll though it is considered to be more saprophytic. Field evidence supports this as the plants are more concentrated near large rotting stumps, logs or at times dead standing trees. More work needs to be done on this to determine the fungi symbiotic relationships.

The true leaves are absent. The alternate, divaricate, lanceolate bracts that replace the leaves measure 45mm to 75mm in length by 13mm to 45mm in width. The cauline bases of the bracts are rounded to slightly cordate while the apexes are acute. The concolourous, thick coriaceous laminas are pale olive-green to yellowish-green and glabrous and lack genuine, efficient sugar producing chlorophyll. The laminas are flat and decurve downwards on the apical half while the margins are entire. The broad, obtuse midvein is more like a thickening of the lamina on the lower lamina. The parallel longitudinal lateral veins with 3 to 5 more prominent than the others are faintly prominent on the upper lamina.

The inflorescences are long, gently curving, pendulant racemes branching to the first or second order and are born from the bracteole axils. The racemes usually have 150 or more individual flowers that are somewhat porrect. The ultimate branches measure 30mm to 140mm in length with 7 to 40 individual flowers. The pedicels measure 24mm to 32mm in length. The floral bracts are scale like, triangular and measure 1mm to 3mm in length. The flowers are star shaped and measure 50mm to 60mm in length by 6mm to 8mm in width. The flowers are golden yellow with pink and red markings on the labellum.

The glabrous linear to oblong, erect dorsal sepal is slightly incurved ate the acuminate apex. The margins are entire and straight or slightly undulating. The dorsal sepal measures 22mm to 25mm in length by 5mm to 7mm in width.

The glabrous oblong to ovate, spreading downward lateral sepals are slightly incurved at the acuminate apex. The margins are entire and straight or slightly undulating. The lateral sepals measures 22mm to 25mm in length by 6mm to 9mm in width.

The glabrous oblong to ovate, spreading upward lateral petals has an acuminate apex. The surface curves slightly backwards from the central, longitudinal, obtuse keel which is prominent on the abaxial surface margins while the margins are entire. The lateral petals measure 15mm to 22mm in length by 4mm to 6mm in width.

The labellum is carmine to carmine-red with except for the pastel yellow to pale yellow margin and central channel. The channel has irregular margins, is narrow at the base and expands to the margins at the apex. The labellum measures 15mm to 20mm in length by 15mm to 17mm in width. The labellum’s margins are crisped and contorted.

The stamens and stigma are fused to form a column that measures 12mm in length. The sweetly scented honey-vanilla flowers appear from October to January.

The fruits are obloidal capsules. The mid green glabrous capsules turn deep grey-brown almost black externally and mid tan internally when ripe. The capsules split longitudinally along the sides. The split segments remain attached at the base and the apex. The capsules dehisce just prior to the following seasons flowers emerging.

The capsules measure 150mm to 270mm in length by 8mm to 14mm in diameter. The seeds are relatively large for an orchid and are winged around the margins. The seeds are usually uniform in size and measure 1.5mm in diameter including the wing.

Wildlife:

Pseudovanilla foliata’s flowers are a rich source of pollen and nectar for local native bees like Tetragonula carbonaria and the Blue banded bee Amegilla cingulata.

The plants are saprophytic and typically reach a peak of vigor and flowering coinciding with the ultimate decay of fallen trees, after which they decline rapidly and die as conditions are unsuitable. It is often conspicuous in the years following logging operations, roadworks and cyclones which coincide with the death of the living trees in the forests.

Cultivation:

Pseudovanilla foliata is a beautiful saprophytic orchid that has proven impossible to grow in cultivation. If you are fortunate enough to have one growing on your property it would be worthwhile fencing it off and protecting it. An annual feeding of blood and bone or top dressing with an animal carcarcus may help or induce good flowering.

Propagation:

Seeds: The seeds are easy to acquire and the seed requires treatment before sowing. Really Orchid seeds are meant for professionals with time, equipment and space. This orchid because of its symbiotic relationship with a fungus or fungi would be extremely difficult to maintain for any period of time when propagating.

Wildlife:

Pseudoweinmannia lachnocarpa’s do not appear to have any predators though the flowers are visited by hundreds of small native nectar eating flies, native bees and beetles.

Cultivation:

Pseudoweinmannia lachnocarpa is a magnificent tall tree that should be more widely grown in tropical, subtropical and monsoonal gardens. It is ideal at the edge of a moist rain forest or as the pioneer trees for a rainforest garden. They also make great park trees offering quick growth, and good shade and forming the beginning of a buttress within 10 year under ideal conditions. In cultivation they will grow from 15 meters to 20 meters in height by 10 meters to 14 meters in diameter when grown in the open or taller and narrower if grown closer together as a rainforest tree.

It is prolific flowers and when it is given an adequate supply of water and a little native fertilizer on a regular basis the plants will respond with excellent flowering and possibly good fruit set over a longer period.

They often reach their full potential in just 12 to 15 years and flower from the eighth to tenth year from seed.

Propagation:

Seeds: The seeds of Pseudoweinmannia lachnocarpa can be easily collected from the fruits that have fallen to the ground.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September and March to maintain better colour, health, vitality and flowering.

Wildlife:

Psilotum complanatum’s wildlife is unknown to the author.

Cultivation:

Psilotum complanatum is an excellent fern for cultivation and makes great fern where dappled light occurs. It is ideal as a bush house specimen for areas where there is heavy to light shade. In cultivation it will grow from 500mm to 750mm in length with a similar spread. It is cold tolerant to temperatures as low as 1 degree once established but detest frosts.

It is most suitable in rainforests where it can break the monotony of large deep green leaves and add texture to the trunks and forks of rainforest trees. It likes plenty of leaf litter to help increase fertility and once established can be fed with apple or banana peels.

Medium to large frog or fish ponds are made the more attractive when surrounded by this fern when it is placed on rocks and boulders. Their size makes for a balance setting.

It is quite hardy and we have successfully grown it as a potted houseplant in the open bathroom setting using tank water.

Repot annually to revitalize soil and increase the growth rate. Repot using our recommended potting mix for ferns for best results.

All ferns that are declared rare, vulnerable or endangered are protected by Federal and State Laws and must not be removed from the wild unless you are a land developer, mining company or main Roads department etc. This includes bulbs, roots, leaves and flowers. No part of any plant can be removed from Federal, State or Local Government land without the prior permission of the authority and this includes the spore.

Most people are put off at the thought of growing ferns from spore. Like all plants that produce their offspring from seed or spore the methods are basically the same. Remember nature has been doing this for millions of years and has been very successful. I have had excellent results growing over 200 different species of Australian ferns so don’t be afraid. Give it a go.

Step 1. Select spore from the fern fronds. Wait until the fern is just starting to release its spore. Rinse the fronds under clean running water and dry. This is to wash off any other spores from rogue ferns that may have settled onto the fronds. (There is nothing worse than having common brake or common soft bracken contaminating a prized tree fern or epiphyte.)

Step 2. Place the dry fronds in a clean brown paper bag and keep them in a cool dark place like the linen closet for about a week to ten days before you are ready to sow the spore. The exception to this rule applies to ferns, which produce green spores. These must be sown immediately that they are released. Todea Barbara is a good example of a fern, which produces green spore.

Step 3. Take a large ice cream container, a small ice cream container and a clean clear plastic bag large enough to seal the large ice cream container and three or four milk bottle tops.

Step 4. Punch or drill 6 to 10 5mm holes in the bottom of the small ice cream container.

Step 5. Wash both containers, tops and plastic bag so that they are very clean and sterile.

Step 6. Use a clean fine seed raising mi. We used 30{98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} fine sand, 30{98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} peat and 30{98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} perlite and 10{98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} vermiculite. We used crushed basalt, crusher dust and peat in a 50:50 ratio for epiphytes. Moisten the mix enough that water does not run out when the mix is squeezed between the fingers.

Step 7. Place the moisten mix (Enough to half fill the small ice cream container) in the microwave oven with a large glass of water for 7 or 8 minutes, until the water is boiling. Allow them to cool in the oven. You will need the water later so do not tip it out.

Step 8. Take the brown paper bag out of the linen closet. Shake the bag and remove the fronds. You should have a yellow, brown, black or rarely greenish brown or ochre powder or very fine, small round pin head size spore depending on the specie involved.

Step 9. Remove the mixture from the oven once it has cooled and place it in the small ice cream container and level.

Step 10. Sprinkle the spore sparsely over the mixture in the small ice cream container.

Step 11. Place the milk bottle tops in the large ice cream container with the flat surface facing down. Place the small ice cream container in the large ice cream container so that it is sitting on the milk bottle tops.

Step 12. Remove the water from the microwave and pour it into the larger ice cream container so there is 25mm to 30mm of water in the bottom.

Step 13. Place the ice cream containers in the plastic bag and seal. Step 14. Place the contents and bag in a warm shady place preferably 50{98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} to 70{98c9b985d4dc543f86c0cb8c6df3d397ea5754df614d759fdd5c1720a0a9cf2f} shade depending on the specie. Shade houses and some window sills are ideal.

Step 15. The surface should turn green within a week to two weeks. The prothallus will then develop. From the prothallus the first true fronds will appear. Wait until the ferns are 20mm to 35mm in height before you attempt to transplant them. Once they are ready open the bag up slightly and allow the air to flow around the little ferns. Every 3 to 5 days open the bag a little further so the ferns get use to their new environment. Allow them a week to two weeks to harden off before you transplant them following the removal of the plastic bag. Carefully prick them out into 50mm standard squat tubes as you would any seedling.

Do not try to transplant them as single plants as they are still a little delicate still.

Once the smaller ones again reach 50mm to 70mm you may wish to divide the stronger and hardier individual plants into smaller clumps in 100mm squat pots.

Step 16. We fertilized with seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis until established. Fertilize every two months for one year even when in the ground.

Height & Spread:

Wild Plants:0.4m to 0.6m by 0.3m to 0.5m.

Characteristics:

Psilotum nudum is a terrestrial, lithophyte or epiphytic plant often growing out the bottom of other epiphytic plants. The rhizomes are short, creeping and covered in deep brown to deep brown lanceolate scales. Psilotum complanatum’s pendant slender aerial stems are regularly branched from the base and measure 250mm to 650mm in length. The concolourous flattened to elliptic in cross section are deep green and glabrous. The basal stems measure 3mm to 5mm in width while the ultimate branches measure 1.5mm to 2mm in width.

The fronds are small to minute scales.

The fertile fronds are similar to the sterile fronds. Psilotum nudum’s orbicular sporangia appear from near the base to almost the apex along both margins.

Spores are small irregular and reddish brown in colour.

The Synangia are 3 lobed sporangia and measure 2mm to 3mm in length by 2mm to 3mm diameter. The spore is pale golden-brown to tan.

Wildlife:

Psilotum nudum’s wildlife is unknown to the author.

Cultivation:

Psilotum nudum is a beautiful fern for cultivation and makes a great fern on exposed rock crevices in a sheltered position. At The Pinnacles it has self spored and is found growing between paving bricks laid on concrete. It is ideal as a bush house specimen for areas where there is heavy to light shade. In cultivation it will grow from 500mm to 650mm in length with a similar spread. It is cold tolerant to temperatures as low as 1 degree once established but detest frosts.

It is most suitable in rainforests where it can break the monotony of large deep green leaves adding texture to the trunks and forks of rainforest trees. It likes plenty of leaf litter to help increase fertility and once established can be fed with apple or banana peels.

Medium to large frog or fish ponds are made the more attractive when surrounded by this fern when it is placed on rocks and boulders. Their size makes for a balance setting.

Psilotum nudum is quite hardy and we have also successfully used it as a potted houseplant in a well lit bathroom setting using tank water.

Repot annually to revitalize soil and increase the growth rate. Repot using our recommended potting mix for ferns for best results.

Characteristics:

Psychotria daphnoides grows as a densely foliaged small shrub. The stems are thin deep brown and becoming green-brown or olive green only near the apex with newer leaf growth. These stems are sparsely covered in lighter coloured longitudinal lenticels. The new growth is blue green and glabrous to sparsely covered in white to fawn hirsute hairs and covered in pale brown spots and markings.

The opposite leaves oblanceolate to obovate or oblong in Psychotria daphnoides var. daphnoides and narrow oblong linear in Psychotria daphnoides var. angustifolia. The leaves measure 20mm to 95mm in length by 5mm to 36mm in width. The base is cuneate while the apex is acute-obtuse to shortly acuminate. The discolourous laminas are deep grass-green, glabrous and glossy on the upper lamina while the lower lamina is paler and glabrous to sparsely covered in off white sericeous hairs. The leaf margins are entire, curve slightly upwards from the mid vein and are recurved or revolute. The mid vein is slightly prominent on the lower lamina and visible from the upper lamina. The petiole measures 2mm to 13mm in length.

Inflorescences of Psychotria daphnoides are born in small terminal cymes. The pale green rachis measures 20mm to 30mm in length while the pedicels measure 7mm to 10mm in length. The peduncules measure 3mm to 5mm while the individual flowers pedicels are sessile to 0.6mm in length. The pale green calyxes measure 1mm to 1.5mm in length. The lobes are reduced to minute teeth. The white corollas measure 2.5mm to 5mm in length while the lobes measure 2mm to 3mm in length. The elliptical lobes have an inflexed, acute apex.

The fruits are succulent and have a taste reminiscent of plums crossed with eucalyptus leaves. The texture is that of a plum.

Cultivation:

Psychotria daphnoides is a magnificent medium shrub that should be more widely grown in tropical, subtropical and monsoonal gardens. The flowers glossy green leaves and white fruits make them beautiful specimens for the garden.

It is ideal at the edge of a rain forest or as an understory shrub for a moist rainforest garden. They also make great hedges being densely foliaged and can be trimmed to maintain a hedge row to 2meters without any problem. For hedges they can be planted at 3 meter centres. In cultivation they will grow from 2.5 meters to 3.5 meters in height by 2 meters to 3 meters in diameter when grown in the open.

Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants will respond with good flowering and possibly better fruit set over a longer period. The white fruits contrast strongly against the large glossy leaves.

They often reach their full potential in just 12 to 15 years and flower from the sixth to seventh year from seed.

It would make a very good bonsai plants.

Propagation:

Seeds: The seeds of Psychotria daphnoides can be removed easily from the fruits that have fallen to the ground or picked when the fruits are mature from the shrubs.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September and March to maintain better colour, health, vitality and flowering.

Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 3m to 5m by 2m to 3m

Characteristics:

Psychotria loniceroides grows as a small tree or densely foliaged shrub. The trunk is tall, straight, pale grey, scabrous and usually covered in green lichens. The stems are thin deep red-brown and becoming green-brown only near the apex with newer leaf growth. These stems are sparsely covered in rusty-brown lenticels. The new growth is deep sea-green and covered in rusty-brown hirtellous to hirsute hairs.

The opposite or off set opposite leaves of Psychotria loniceroides are elliptical, oblong to oblanceolate. The leaves measure 50mm to 140mm in length by 15mm to 50mm in width. The bases are rounded tending cuneate close to the petiole while the apexes are shortly acuminate to acute. The discolourous laminas are deep green to sea-green and sparsely to densely covered in rusty-brown to rusty-red hirtellous to hirsute hairs on the upper lamina while the lower lamina is paler. The leaf margins are shallowly sinuate, flat and curve slightly upwards from the mid vein.

The green capsules turn creamy yellow to pale yellow when ripe. The calyx is persistent. The small brown ovoid seeds are compressed on one side and measure 2mm to 3mm in length.

Wildlife:

Psychotria loniceroides’s do not appear to have any predators.

The fruits are succulent and have a taste reminiscent of plums crossed with eucalyptus leaves. The texture is that of a plum.

Cultivation:

Psychotria loniceroides is a magnificent medium shrub that should be more widely grown in warm temperate, subtropical, tropical and monsoonal gardens. The flowers glossy green leaves and white fruits makes it a beautiful specimen shrub for the garden.

It is ideal at the edge of a rain forest or as an understory shrub for a dry rainforest garden. It also makes a great hedge being densely foliaged and can be trimmed to maintain a hedge row to 2 meters without any problem. For hedges they can be planted at 3.5 meter centers. In cultivation they will grow from 3.5 meters to 5 meters in height by 2.5 meters to 3.5 meters in diameter when grown in the open.

It grows exceptionally well on lighter soils where deep leaf litter keeps the soil cool and moisture at an even level. If these requirements are met it can cope with temperatures as low as minus 4 degrees and up to 42 degrees. It is moderately drought resistant but is slow in the initial years and will drop leaf if moisture is restricted.

Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants will respond with good flowering and possibly better fruit set over a longer period. The pale yellow fruits contrast strongly against the large glossy leaves.

Garden beds would need to be open with plenty of space between plants to allow air flow as well as to give the branchlets a chance to spread and be appreciated for their unique beauty. Crowding this type of foliage with other plants will see them lose all the effectiveness of the colour and form you require or want. Place it near paths so the interesting leaf venation can be viewed regularly. Correct spacing will contrast the foliage better without one overpowering the other. For mass planting space the plants at least 4 meters to 5 meter centres. If you are using it amongst rocks or boulders on rocky ground, plant them sparingly to attain a barren scene, or interplant them with wild flowers to make strong uplifting of colour. 2 or 3 in an area of 100 square meters would be ample. The use of annuals helps to attract the viewer to the permanent plants foliage as it is the predominant foliage you want people to notice in the patch. In the case of Psychotria loniceroides you could substitute very small Grevillea like Grevillea masonii or Grevillea thelminiana. Most annuals flower have bold colour flowers so will not clash and the constant whiff of perfume will complete the scene. Annuals mixed with Psychotria loniceroides help to give small gardens depth and make it look larger than what it really is, especially if the plants are pruned to maintain a smaller bushier shrub.

It would probably make a very good bonsai plant as it is easy to work and the stems have good flexibility.

Propagation:

Seeds: The seeds of Psychotria loniceroides can be removed easily from the fruits that have fallen to the ground.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

It grows exceptionally well on lighter soils where deep leaf litter keeps the soil cool and moisture at an even level. If these requirements are met they can cope with temperatures as low as minus 4 degrees and up to 38 degrees. It is moderately drought resistant but are slow in the initial years.

This makes them great for hedges being densely foliaged and can be trimmed to maintain a hedge row to 2 meters without any problem. For hedges it is best planted at 3.5 meter centres.

Garden beds would need to be open with plenty of space between plants to allow air flow as well as to give the branchlets a chance to spread and be appreciated for their unique beauty. Crowding this type of foliage with other plants will see them lose all the effectiveness of the colour and form you require or want. Place them near paths so the interesting leaf venation can be viewed regularly. Correct spacing will contrast the foliages better without one overpowering the other. For mass planting space the plants at least 4 meters to 4.5 meter centres. If you are using them amongst rocks or boulders on rocky ground, plant them sparingly to attain a barren scene, or interplant them with wild flowers to make strong uplifting of colour. 2 or 3 in an area of 100 square meters would be ample. The use of annuals helps to attract the viewer to the permanent plants foliage as it is the predominant foliage you want people to notice in the patch. In the case of Psychotria loniceroides you could substitute very small Grevillea specie or natives for native annuals like Xerochrysum bracteatum, Xerochrysum viscosum and Dampiera specie. Most annual flowers have bold colour flowers so will not clash and the constant whiff of perfume will complete the scene. Annuals mixed with Psychotria loniceroides help to give small gardens depth and make them look larger than what they really are especially if the plants are pruned to maintain a smaller bushier shrub.

It would make very good bonsai plants.

Propagation:

Seeds: The seeds of Psychotria simmondsiana can be removed easily from the fruits that have fallen to the ground.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. When the seedlings are 20mm to 25mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Fertilize using seaweed, fish emulsion or organic chicken pellets soaked in water on an alternate basis. Fertilize every two months until the plants are established then twice annually in early September and March to maintain better colour, health, vitality and flowering.

Specie: From Attenuāta, which is Latin for thin, slender or weak looking. It usually refers to leaves or phyllodes, which are slender and fine.

Sub specie:

Common Name:

Distribution:

Psydrax attenuata is a widespread specie found in the northern half of the continent.

https://avh.ala.org.au/occurrences/search?taxa=Psydrax+attenuata#tab_mapView

Habitat Aspect Climate:

Psydrax attenuata prefers full sun. It is found in drier areas where moisture is retained in the soil, like riparian zones on undulating plains especially on pindan soil depressions. The altitude ranges from 500 meters ASL to 800 meters ASL.

The temperatures range from minus 3 degrees in July to 36 degrees in January.

The rainfall ranges from lows of 150mm to 1600mm average per annum.

Soil Requirements:

Psydrax attenuata prefers red sands, red clay loams with gravel, stony loams, red aluminium soils and pindan clays. The soils are usually derived from decomposed brown basalt, black basalts, sandstones, granites, shale or metamorphic rock sediments, which are often laid down on creek or stream meanders. The soils pH ranges from 4pH to 6.8pH. Plants are subject to wide fluctuations in available moisture from droughts to water logging in the wet season. Non saline soils to very saline soils are tolerated.

Height & Spread:

Wild Plants:3m to 10m by 2m to 6m

Characteristics:

Psydrax attenuata grows as a wide spreading densely foliaged small tree. The trunk is crooked, grey, with irregular tessellated patches and usually covered in green lichens in cooler moist coastal terrains. The stems are thin grey and glabrous becoming brown only near the apex with newer leaf growth. The new growth is olive green and glabrous.

The alternate, disjunct leaves are near the apex of the branchlets. The narrowly elliptical to linear leaves measure 50mm to 140mm in length by 15mm to 30mm in width. The bases are attenuate while the apexes are acuminate. The concolourous laminas are olive-green, glabrous and dull to semi glossy on the upper laminas while the lower laminas are paler and dull. The leaf margins are entire or shallowly sinuate and are flat or slightly undulating on those leaves that are broader. The mid vein is prominent on the upper lamina and is distinctly visible on the lower lamina while the lateral veins are level or slightly prominent on the upper lamina. The petiole measures 3mm to 5mm in length. The linear stipules are caducous. The domatia are protected by foveola with very small openings. Leaves are brittle and crack when bent or folded.

Inflorescences of Psydrax attenuata are born in large terminal cymes. The pale green calyxes measure 0.4mm to 0.6mm in length. The white corollas measure 5mm to 9mm in length while the 6 lobes measure 6mm to 10mm in length by 2mm in width. The linear lobes recurve with the apexes being obtuse to acute-obtuse. The lobe margins are covered in papillose lumps.

The 6 exerted white stamens are free for their entire length. There is a ring of downward pointing, white, hirtellous hairs at the same point where the filaments are attached to the hypanthium. The filaments measure 6mm to 8mm in length while the anthers measure 3mm to 4mm in length.

The yellow style is glabrous and measures 8mm to 10mm in length while the peltate stigmas measure 2mm to 3mm in length by 1.5mm to 2.2mm in diameter. Psydrax attenuata’s sweet scented flowers appear in April.

Psydrax attenuata’s fruits are globose to ovoidal drupes. The drupes contain 3 seeds and are glabrous. The trigonous berries measure 5mm to 6mm in length by 5mm to 6mm in diameter. The green capsules turn deep purple-black when ripe. The 3 to 5 laterally ovoidal seeds are glossy brown to black.

Wildlife:

Psydrax attenuata’s are known to host many species of the Papilio butterflies like the citrus swallow tail, Papilio aegeus.

The succulent fruits are edible however I have not eaten these fruits and are not able to comment on the flavour.

Cultivation:

Psydrax attenuata is useful small tree that should be more widely grown in tropical, subtropical and monsoonal gardens. It is an ideal small tree for semi-arid home gardens. They offer quick growth, and reasonable shade when cultivated compared to their wild cousins that are rather spindly. In cultivation it will grow from 8 meters to 10 meters in height by 6 meters to 8 meters in diameter when grown in the open.

It can be pruned to maintain a smaller bushier shrub of around 3 meters to 4 meters in height by 3 meters to 4 meters in diameter.

It is moderately drought resistant once established even in its habitat.

Add to the above, if it is given an adequate supply of water and a little native fertilizer on a regular basis the plants will respond with good flowering and possibly good fruit set over a long period.

Garden beds with rocky embankments would be open with plenty of space between plants to allow air flow as well as to give the branchlets a chance to spread and be appreciated for their unique beauty. Crowding this type of foliage with other plants will see them lose all the effectiveness of the colour and form you require or want. Correct spacing amongst boulders will contrast the foliage better without one overpowering the other. For mass planting space the plants at least 8 meters to 10 meter centres. If you are using them amongst rocks or boulders on rocky ground, plant them sparingly to attain a barren scene, or interplant them with wild flowers to make strong uplifting of colour.

Annuals mixed with Psydrax attenuata help to give small gardens depth and make them look larger than what they really are especially if the plants are pruned to maintain a smaller bushier shrub. I would not use any more than two small shrubs as fill in plants and in fact one correctly placed would give balance and make the trees look taller than they really are.

Propagation:

Seeds: The seeds of Psydrax attenuata can be removed easily from the fruits that have fallen to the ground or collected from the trees.

Sow fresh seeds directly into a seed raising mix, keeping them moist not wet. When the seedlings are 20 to 25 mm tall, prick them out and plant them into 50mm native tubes using a good organic mix.

As the seedlings roots reach the bottom of the tubes plant them out into their permanent position. Do not delay.

Class: Pteridopsida or Filicinae

Order: Dennstadtiales

Family: Dennstadtiaceae

Genus: From Ptéris, which is Ancient Greek for a fern. It refers to plants, which is any seedless, nonflowering vascular plant of the class Filicinae, of tropical to temperate regions, characterized by true roots produced from a rhizome, with fronds that uncoil upward and have a branching vein system, and reproduction by spores contained in sporangia that usually appear as brown or yellow grains or powder from on the underside of the fronds.

Specie: From ēsculentum, which is Latin for edible, to nourish or delicious. It refers to plants, which have good eating qualities.

Sub specie:

Common Name: Bracken Fern.

It is known as Gurgi in the Eora Aboriginal language, while in the local Gumbaynggirr know it as Gamiiny.

Distribution:

Pteridium esculentum is widespread specie which circumnavigates most of Australia including Tasmania and many of the larger Islands off the coast.

It is a fern that is found worldwide.

Note: Pteridium esculentum needs to be reassessed as there appears to be more than one species. As the species is worldwide and well spread it will be a massive job to collate any possible new species for identification. The Australian plants will be reallocated a new name under nomenclature rules if found to be different from the type species.

https://avh.ala.org.au/occurrences/search?taxa=Pteridium+esculentum#tab_mapView

Habitat Aspect Climate:

Pteridium esculentum prefers full sun to part shade. It grows in most habitats including wet Eucalyptus forests to open Woodlands. The altitude ranges from 2 meters ASL to 1080 meters ASL.

The temperatures range from minus 6 degrees in July to 36 degrees in January.

The rainfall ranges from lows of 400mm to 3200mm average per annum.

Soil Requirements:

Pteridium esculentum prefers a wide range of soils from those derived from decomposed sandstones, brown basalts, black basalts, shale metamorphic, conglomerates or at times heavier sandstones, heavier granites or limestones. The soils pH ranges from 2.8pH to 8PH however extreme PH’s limit healthy growth. Best growth is achieved when the pH is between 4.5PH and 7PH. Plants are subject to wide fluctuations in available moisture from droughts to seasonal water logged soils. Non saline soils to very saline soils are tolerated.

Height & Spread:

Wild Plants: 1m to 2m by 2m to several hundred square meters.

Characteristics:

Pteridium esculentum rhizome is very long creeping slender and fleshy with a diameter of 3mm to 10mm. The deep green to a mid blue-green or amber honey rhizomes are covered in deep red-brown to deep rusty brown hairs.

Pteridium esculentum’s has broad triangular fronds. The fronds measure 600mm to 1800mm in height by 400mm to 550mm in length by 400 to 600mm in overall width. The slender 600mm to 2000mm stipes are glossy brown and glabrous except for a dense covering of red- brown hairs close to the base. The minor rachis has two wing like lobes between the segments.

The lamina on the 3 to 4 pinnatifid fronds is glabrous. The laminas are thick but not coriaceous. The discolourous laminas are deep glossy green. The lobes along the final rachis are linear with entire margins. The lobes vary considerably with the apex lobe being much longer than the lateral lobes. The lateral lobes measure 7mm to 13mm in length by 4mm to 7mm in width. The mid vein and main lateral veins on the lobes are prominent on the lower lamina and are visible on the upper lamina.

The fertile fronds are similar to the sterile fronds but the lobes are narrower and measure 5mm to 10mm in length by 2mm to 3.5mm in width. Pteridium esculentum’s sori are a continuous strip beneath the in rolled margins to almost the mid vein. The bilipped indusium has one pale green lip while the other lip is pale yellow-brown.

Spores are very small. It is a pale fawn to pale yellow brown in colour.

Wildlife:

Pteridium esculentum’s is known to be the host for the Idiodes apicata butterfly. A study conducted near Sydney revealed that over 33 different insects inhabit Pteridium esculentum while at the same time there was a lack of ants, bees, wasps and beetles. (Shuter, E. and Westoby, M. (1982). Herbivorous arthropods on bracken)

This plant has not been accepted into the diets of westerners probably because of the carcinogen ptaquiloside. If the new croziers are cooked or the roots are roasted and the starch removed the carcinogens are destroyed.

Cultivation:

Pteridium esculentum makes an excellent ground cover and phytoremediator for areas where there is filtered light to dense shade. It always look green and fresh especially where adequate ground moisture is retained in the soil. It is excellent on heavy clay soils where it can be used for breaking the heavy clays up and making them more porous. As garden subjects they will colonize rocks especially those of a more porous nature. It is cold tolerant to temperatures as low as minus 4 degree once established.

Most people consider it a weed and an annoyance where it grows naturally.

We had some Chinese friends here from inner Chong Qing city. One lady; knowing I loved ferns, commented on the beauty of the ferns growing in the north west corner beside the path. On querying her I realised she was talking about Pteridium esculentum. I took it as a compliment and let her believe it was required there. In fact I had recently cut it back and the new growth to her looked stunning. The moral of the story is different people find beauty in different forms that plants exhibit.

The rainfall ranges from lows of 500mm to 2000mm average per annum.

Soil Requirements:

Pteris comans prefers light fatty clays to medium clays often with copious quantities of forest litter. The soils are usually derived from decomposed brown basalt, black basalts, sandstones, granite, shale, conglomerates or metamorphic rocks. The soils pH ranges from 4.5pH to 7pH. It does not tolerate water logged soils. Non saline soils to moderately saline soils are tolerated.

Height & Spread:

Wild Plants: 0.6m to 1m by 0.6m to 1m.

Characteristics:

Pteris comans rhizome are tufted, erect and covered in deep brown to deep brown hairy scales.

Pteris comans’s slender 400mm to 200mm stipes are deep purple-brown near the base, glossy brown above turning green and glabrous with a groove on the upper side.

The lamina on the tripinnatifid fronds is deeply divided. The rachis is golden yellow. The fronds measure 350mm to 450mm in length by 180mm to 250mm in width. The laminas are thin but not coriaceous, glabrous. The laminas lobes number 6 to 12 pairs with a terminal pinna. The concolourous laminas are green to a mid blue-green, dull and glabrous or are very sparsely covered in white pilose hairs. The opposite ultimate lobes are oblong and measure 15mm to 25mm in length by 6mm to 10mm in width. The margins are finely, irregularly toothed.

The fertile fronds are not much narrower than the sterile fronds. Pteris comans’s linear sori are continuous from near the base to over half way to the apex on the lower margin. The upper margin may have a continuous or interrupted line near the margin.

Spores are very small. It is a pale fawn to pale yellow brown in colour.

Wildlife:

Pteris comans’s wildlife is unknown to the author.

Cultivation:

Pteris comans makes an excellent ground cover for areas where there is heavy shade that is always moist. They always look green and fresh especially where adequate ground moisture is retained in the soil. It is very suitable on medium clays to heavy clay soils and are most suitable for small medium and large gardens close to the coast in warm temperate, warm sub-tropical or cool tropical gardens. As garden subjects they will colonize soils that have established rainforests or at the bottom of moist shady banks. It is cold tolerant to temperatures as low as minus 3 degrees once established.

It is most suitable for use as a rainforest understory plant where they can break the monotony of large deep green leaves. They like plenty of leaf litter to help increase soil fertility, maintain soil moisture and to maintain a cool root zone.

Medium to large frog or fish ponds are made the more attractive when surrounded by this fern which can spread over large areas if given the opportunity without becoming problem some. Their size makes for a balance setting.
