Vegetative features in identification of a native tree or shrub can be divided into a number of categories. They include; leaf, flower, fruit, bark characteristics and the size, shape and form, collectively called the habit of the plant. Comprehensive information on leaf features, bark texture and distribution range are given for each native tree species. The content of the web page below is constantly extended, revised and updated. We aim to build up the awareness to the high conservation values Australian rainforest areas deserve. Species in the following genera are listed in groups on our web pages: Australian Fig trees (Ficus spp.), Australian Eucalypts (Eucalyptus spp.), Grevilleas (Grevillea spp.) and Syzygium species (Lilly Pillies). Otherwise all native Australian tree species are listed in alphabetical order.
Narrow-leaved Geebung Persoonia virgata Other names: Small-leaved Geebung, Wallum Geebung
This woody and multi-branching shrub rarely exceeds a height of more than 4m. Its preferred habitat includes open dry forests and heath lands in the proximity to the coastline. Geebungs belong to the large and distinctive genus of Persoonia, which has a wide distribution range covering every state of Australia. Persoonia species occur in diverse environments ranging from rainforests to arid regions (1). Fresh bark is a reddish brown in colour and becomes rough and fissured on older stems (2). The fleshy fruit, a drupe, is very characteristic for the genus and features the persisting hardened flower style at the apex, which is also typical for members of the Protea family (PROTEACEAE). The mature fruit of this species turns a yellowish green and is circa 1.5cm long at full maturity. The skin covers a translucent fruit flesh that becomes very sticky on exposure to air (3 & 4). Simple leaves with an alternate arrangement (when matrue) are; up to 5cm long, narrow linear in shape, hairless when mature, dark green, semi-glossy on top, paler beneath, strong and somewhat rigid in texture. Leaf apex terminates in a fine tip. Distribution: Central-coast of NSW to Qld.
See the Botanical Species List to locate other Persoonia species (Geebungs) on this website.
Narrow-leaved Orangebark Maytenus silvestris
This native shrub or small tree is found in moist tall forests adjacent to rainforests and in dryer open forests dominated by Eucalyptus species (Picture 1). Freshly exposed bark is an orange-brown changing to a grey brown colour with age and has a firm texture (2). Small greenish white flowers measure around 4 to 5 mm in diameter with five broadly rounded petals. They are held on individual flower stalks or small racemes (3). The fruit (a capsule) is ovoid in shape and up to 7 mm in length, turning orange in colour when ripe (fruit shown is still immature). The remaining flower calyx at the base and the persistent style at the top of the fruit make good identification characteristics (4). Simple leaves with an alternate arrangement are; up to 8 cm long, narrow at less than 15 mm wide, mostly lanceolate in shape, showing entire margins towards the base but often with a few spines towards the apex, dark green on top, hairless, rather thick and stiff in texture. Leaf apex shape is acute, base shape is cuneate. Venation is fine but visible and the short petiole is only 2-3 mm in long. Distribution: NSW south coast to Qld.
Note: This species intergrades with the Orange Bark Maytenus bilocularis (same page), where both species share a habitat. See Flower Characteristics Page and Leaf Characteristics Page for information on terms used.

Needle Shaggy Pea Podolobium aciculiferum
This upright shrub can reach 3 to 4m in height and is common occurrence in Eucalypt dominated forests ranging from the coastline to higher altitudes. As the common name implies it is covered in thin needle-like spines making it relatively easy to identify (1). Trunks and older branches of mature plants lose their spines and bark becomes finely rough with a granular texture. Bark colour on old growth is brown (2). Bright yellow or more orange coloured flowers are characteristic for the pea bean family (Fabaceae) and measure about 1 cm in diameter. They are either borne individually on long, curved stalks or on short racemes appearing along young branches, and bloom over spring and summer (3). At first small pods are light green in colour and covered in whitish hair, but become hairless and darker green when fully mature. They reach about 1 cm in length and contain between 2 to 4 cream coloured seeds (4).Young branches are light green in colour, covered in fine, white hair and pairs of sharp spines. Simple leaves vary between an opposite (more likely) and an alternate arrangement. They are; up to 2.5 cm long (including needle tip), broadly lanceolate to ovate in shape with fine crenate margins, dark green, semi-glossy, hairless on top, paler green, sparsely hairy beneath, strong, stiff and slightly rough in texture. Leaf apex is acute ending in a needle-like tip; base is broadly wedge-shaped (5). Distribution: From NSW south coast to central Qld. Note: Similar in appearance to the Prickly Shaggy-pea (Podolobium ilicifolium), which has lobed leaves.

They consist of up to 40 leaflets which are; up to 20 cm long, narrow lanceolate or elliptic in shape with undulating margins, dark green above, only slightly paler beneath, mostly hairless when mature, firm and rather rigid in texture. The short petiolule (leaflet stalk) has swollen a base and the prominent centre vein is raised on both surfaces (5). Distribution: Far North Qld.
Norfolk Island Pine Araucaria heterophylla
The natural distribution of this stately tree is restricted to Norfolk Island, but it is a common ornamental tree planted along Australia's foreshore and in many other parts of the world. The distinctive symmetrical shape (habit) and impressive height of more than 50m makes identification of this species relatively easy (1). Bark on older specimen is very rough, flaky in texture and grey-brown in colour (2). The male cone develops at the very end of branchlets and reaches up to 10 cm in length (3). The female cone disintegrates on the tree and the fallen individual cone scales, containing the edible seed, can be collected beneath the tree. The seed, shown in the middle of the image, measures about 4 cm in length. Leaves of mature trees are arranged in a whorl formation. They are; claw-like in shape, up to 10 mm long, hard and prickly to touch (5). Distribution: Norfolk Island, about 1400 km east of the New South Wales north coast. Note: Closely related to the Hoop Pine A.cunninghamii (Page 7) and the Bunja Pine A.bidwillii (Page 2), all conifers but not true pine trees.

Pink Laceflower Tree Archidendron grandiflorum Other names: Tulip Siris, Fairy Paint Brush
This small native tree occurs as an under-storey species within and on margins of subtropical and littoral (close to thecoast) rainforests, where it can reach a height of 10 to 15m. This species is rather uncommon in its natural habitat and individual or small groups of trees might only be found a fair distance apart. Encountering a mature specimen in full flower gives meaning to the name of Fairy Paint Brush (Picture 1). Young bark is brown in colour turning grey with age (white colouring is due to lichen), texture on older specimens becomes rough, furrowed and scaly (2). Grandiose flowers are protected by white to yellowish petals opening to reveal a multitude of white (at base) to dark pink (at top) stamens, which are up to 5 cm long and topped by yellowish anthers. Flowers are short lasting and will deteriorate quickly when it rains, they are held in tight clusters of up to 6 individuals at the end of young branches. A pronounced green calyx is less than a 1 cm long and petals measure up to 2 cm in length (3). Large bipinnate compound leaves can feature up to 3 pairs of pinnea with 4 to 8 leaflets each, with leaflets increasing in size towards the end. They are; mostly between 3 to 8 cm long (sometimes longer), elliptic, wide lanceolate to ovate in shape with entire broadly undulating margins, mostly hairless, dark green and glossy on top with a thin, papery but strong texture. Leaflet apex is long acuminate, base shape is broadly cuneate to rounded. Noticeable upright glands at leaflet intersections and along rachis are a helpful identification feature (Pictures 4 & 5). Distribution: From to NSW mid-north coast to northern Qld. See also White Laceflower Tree Archidendron hendersonii Page 12.
Pink Walnut Endiandra sieberi Other Names: Hard Corkwood
This small to medium sized native tree is found mainly as an understorey species in different types of rainforests and more open forests (Picture 1). The bark despite the corky look it is rather firm in texture, grey with a pink hue in colour and with maturity develops deep furrows (2). Flowers held on long panicles are 5 to 7 mm in diameter and feature 6 white petals with a yellow and red centre (3). Simple leaves with an alternate arrangement are; up to 10 cm in long, elongated elliptic in shape with entire margins, dark green, glossy on top, mid green and shiny beneath, hairless, smooth and rather leathery in texture. Leaf apex ends in a blunt point, base shape is cuneate. Mid vein is prominent white to pale yellow in colour and fine reticulate venation is visible on lower leaf surface. Distribution: NSW south coast to Qld.
Plum Myrtle Pilidiostigma glabrum
This attractive native shrub reaches a height of 4 to 5m and is found as an under-storey species within subtropical rainforests but also in dryer open forests and in proximity to the coast (Picture 1). The bark of the Plum Myrtle Pilidiostigma glabrum is distinctive with its scaly texture on older branches being a good identification feature. Bark on young stems is smooth in texture and a reddish (to purple) brown in colour (2). Single gorgeous white flowers can reach 2.5 cm in diameter and are held on stalks up to 2 cm long (3). The purple/black fruit measures up to 18mm in length and is topped by the remaining sepals of the flower (4). Simple leaves with an opposite arrangement are: up to 10 cm long, mostly elliptic in shape with entire margins, rather glossy and smooth on both sides. Leaf apex is short acuminate, base shape is cuneate. The mid-vein is pronounced whereas lateral and net veins are faint but do not extend to the leaf edge (5). Distribution: From the NSW mid-north coast to central Qld. Note: This native species is very suitable for suburban backyards. See Leaf Characteristics Page for explanations of terms used.
Poison Peach Trema tomentosa var. viridis Other names: Native Peach, Peach-leaved Poison Bush
This adaptable shrub or sometimes small tree has a very wide distribution range from temperate to tropical climates. It can reach up to 5m in height mostly on a single stem/trunk with an upright shape (Picture 1). Bark is grey to light brown in colour and has a firm and slightly rough texture due to numerous blisters (lenticels) covering the surface (2). Green/white coloured flowers are small only measuring a 3 to 4 mm in diameter and emerge from axillary buds on single stalks or in small cymes (3). The fruit (a drupe) changes from green to a glossy black in colour when fully ripe and is globose (globe shaped). It can reach up to 5 mm in diameter and contains a single hard seed (4). Simple leaves with a regular alternate arrangement are; up to 9 cm long, lanceolate or more ovate in shape with fine serrated margins, bristly hairy on both surfaces, thin, soft and rough in texture.

Distribution: From Vic. to northern Qld and in tropical Asia.
Port Jackson Cypress Pine Callitris rhomboidea Other names: Oyster Bay Pine, Port Jackson Pine
This native conifer has a wide distribution range and is adaptable to different environments occurring within and on margins of cooler rainforest types and in drier open forests. It is a shrub or small tree normally less than 10m in height with an attractive and dense canopy (Picture 1). Bark is brown in colour with older bark weathering to grey, deeply furrowed and rough in texture (2). The indehiscent cone (before opening) is dark, greyish brown in colour and measures about 2 cm across. When fully ripe it will harden to a woody consistency and split into 6 separate segments (valves) (3).
