Australian Tree Identification by Flower Characteristics; Vic, NSW & Qld

Composition of flowers and their arrangement (inflorescence types) play an important role in the classification of Australian trees and shrubs. View the Flower Identification page for more information. Find informative descriptions and enlarged photos of native forest trees showing flower characteristics, leaves, bark, and fruit samples to aid in the identification of native species. We hope to raise the awareness to the high conservation value of remaining old growth rainforests in Australia with these web pages. Species in following genera are listed in groups on our web pages: Australian Fig trees (Ficus spp.), Eucalypts (Eucalyptus spp.), Grevilleas (Grevillea spp.) and Lilly Pillies, Satinashes ( Syzygium species). Otherwise all native Australian tree species are listed by common name in alphabetical order. Note the genus name and use the Botanical Species List to locate related species.

Brittlewood Claoxylon australe

Brittlewood Claoxylon australe
The Brittlewood Claoxylon australe is a small attractive tree or large shrub (depending on conditions) reaching a maximum height of less than 10m. It occurs naturally in a wide range of environments from exposed coastal positions to within subtropical rainforests (Picture 1). Bark (on mature specimen shown) is firm with a rough texture due to bands of small horizontal blisters. It is cream coloured, whereas bark on young trees is olive green (2). Small white flowers with prominent stamens are held on racemes up to 15 cm long (3). The rounded fruit (a capsule) measures up to 8 mm in diameter and features 3 lobes, each containing a red coloured seed (fruit will turn nearly black before opening) (4). Alternately arranged simple leaves are; up to 16 cm long, varied in shape from elliptic to obovate with irregular toothed margins, hairless, dark green and very glossy on top, paler beneath and rather thin with a soft texture. Special identification characteristics are the small glands (Picture5 inset) at the top of the petiole, which are visible on every leaf. Apex shape is acute, base shape is cuneate to nearly rounded. Mid-vein and curved laterals are very evident and distinctly raised on lower leaf surface (5). Distribution: NSW south coast to Qld.

Broad-leaf Star Hair Astrotricha latifolia

Broad-leaf Star Hair Astrotricha latifolia Other names: Broad-leaf Star-hair
The Broad-leaf Star Hair occurs as an understorey species on margins of rainforests, where it is mostly an upright shrub less than 4m tall, whereas in dryer and more open forests it can reach nearly 10m in height (Photo 1). Bark is olive green with a firm and rough texture due to warty blisters (lenticels) covering the surface on older specimens (2). Over spring to early summer (southern locations) large spread-out panicles hold numerous minute greenish flower, which reach about 4 mm in diameter. Five stamens are topped by yellow anthers and in the centre the flower style is divided at the base. Globe-shaped hairy flower buds (centre left) are visible in the image (3). The small ovoid shaped fruit turns greenish yellow in colour and shows the remaining petals (sepals) and the split style at the flattened apex. It is quick to develop, so flower buds, open flowers and maturing fruit can be found on the same panicle (4). Simple alternately arranged leaves are; varied in length from 8 to more than 20 cm, mostly oblong in shape with entire or slightly undulating margins, mid-green, rather dull and hairless on top, whitish grey beneath due to a dense cover of woolly hair (star hairs), rather soft and thin in texture. Leaf apex is attenuate, base shape is cordate. The straight petiole is up to 8 cm long and covered in woolly hair. Young growth and stems are also hairy. Venation is clearly visible on lower leaf surface with mid rib and laterals veins being strongly raised (5). Distribution: Southern NSW to Qld. See Flower Characteristics Page and Leaf Characteristics Page for information on terms used.

Brush Wedding Bush Ricinocarpos speciosus

Brush Wedding Bush Ricinocarpos speciosus Other names: Long-haired Ricinocarpos
This pretty native shrub up to 3m high occurs on margins of different rainforest types and in more open tall forests. It has become increasingly rare and has been listed as a threatened species (Picture 1). Bark is brown to grey in colour and features fine longitudinal fissures. It is hard and slightly rough in texture (2). Gorgeous flowers are up to 20 mm in diameter and bloom over winter to early spring. A tightly packed bundle of stamens identifies a male flower (3a top), whereas the female (3b bottom) has an ovary with a pink style in the centre. The style splits into 3 parts at the base, with each branch forking again. Botanical sources describe this species as monoecious where unisex male and female flowers appear on the same plant. In contrast prolonged observation by the author on a local population of more than 50 specimens (in a restricted area) has shown that male and female flowers in the vast majority of cases are borne on separate shrubs (dioecious in this location). Please Contact Us if you like to make a comment on the subject (3). The fruit, a small hairy capsule with mostly 3 lobes, is seated on the remaining hairy calyx and about 1 cm long. Each lobe (valve) contains an oblong shaped and black coloured seed (inset) (4). Simple leaves with an alternate arrangement are; up to 8 cm long, mostly oblong in shape with entire (recurving) margins, dark green and nearly hairless on top when fully mature, densely hairy beneath. Long brown hair, with lateral branches at the apex (star hairs), covers young branches, petioles and centre veins on underside of leaves. Venation except for centre vein is otherwise obscure (5). Distribution: NSW mid-north coast to southern Qld.

This medium sized tree is found in subtropical and tropical rainforests in proximity to the coast, but also occurs in drier environments at higher altitudes. It is cultivated for its edible fruit and attractive appearance, and has been planted outside its natural distribution range (Photo 1). Bark on older trunks becomes rough, fissured and scaly in texture, whereas younger branches and stems have a smooth texture (2). The shiny, dark purple coloured fruit (a drupe) measure up to 4 cm in diameter and ripens from late summer into autumn. A plum-like fleshy layer surrounds the single, very hard, woody and unusual shaped seed (3 & 4). A pinnate compound leaf consist of 7 to 11 leaflets, which are; up to 10 cm long, elliptic to more ovate in shape with entire margins, hairless to sparsely hairy, dark green, glossy on top, paler green beneath, smooth and strong in texture. Leaflet apex shape is rounded or broadly pointed, base shape is asymmetric. Domatia running along the centre vein are clearly visible on the lower leaflet surface (5). Distribution: From southern to northern Qld.

Burrflower Tree Neolamarckia cadamba

Burrflower Tree Neolamarckia cadamba Other names: Leichhardt Pine
In Australia this medium sized tree is found in dry lowland tropical rainforests and in vegetation fringing watercourses (1). Bark is shades of grey in colour and rough in texture due to fine fissures and blisters covering the surface (2). Yellow to orange coloured flower heads are perfectly rounded and measure approximately 4 cm in diameter. The image shows the tightly packed flower buds before opening (3). Newly emerging leaves are salmon coloured and stipule scars on young branches at leaf nodes are clearly visible (4). Large simple leaves with an opposite arrangement are; more than 30 cm long, obovate or broadly oblong with entire or broadly undulating margins, hairless, dark green on top, paler green beneath, thick and firm in texture. Apex is acute ending in a fine tip; base shape is broadly rounded. Venation is very prominent with laterals being strongly raised on lower leaf surface (5). Distribution: Northern Qld.

Bushy Tamarind Toechima pterocarpum

Bushy Tamarind Toechima pterocarpum Other names: Orange Tamarind
This densely foliated small tree or large shrub is an understorey species and naturally occurs in tropical rainforests where it can reach a height of 6m. Due to extensive clearing it now listed as an endangered species (1). Bark is a dark olive grey colour and has a firm slightly rough texture (2). The orange coloured fruit is a capsule showing three flattened lobes (wings) and measures up to 3 cm in length. It contains 3 shiny black seeds which are partly covered by a yellow aril at the apex (3). Pinnate compound leaves feature up to 8 leaflets, which are; up to 12 cm long, elliptic in shape with broadly undulating (wavy) margins, hairless, dark green, glossy on top, firm and smooth in texture. Leaf apex is acute, ending in a fine point; base shape is cuneate. The petiolule (leaflet stalk) is about 1 cm long and shows a swelling at the base (4). Reticulate leaf venation is very noticeable as mid rib, lateral and net veins are raised (5). Distribution: Rare in lowland tropical rainforests in northern Qld.
