We present quality images of native Australian trees and rainforest species found on Australia's East Coast, with an emphasis on tree species occurring in rainforests. Images showing leaf, bark and/or flower, fruit samples together with detailed descriptions assist in the identification of native tree species.
Species in following genera are listed in groups on our web pages: Ficus sp. (Australian Fig trees), Eucalyptus sp. (Australian Eucalypts), Grevillea sp. (Grevilleas) and Syzygium species (Lilly Pilly). Otherwise all native Australian tree species are listed in alphabetical order.
Antarctic Beech Nothofagus moorei Other names: Negrohead Beech
Fossilised parts of this ancient native tree species have been found in Antarctica and are up to 60 million years old. Its' natural habitat are cool temperate rainforests in mountainous areas where is can grow to a height of 40 m or more (Image 1). Bark has a rough and scaly texture whereby the weathered top layer is a greyish brown colour shedding in irregular sized plates to reveal a reddish brown new bark (2). The hard fruit is covered in rough prickles and measures up to 8 mm in length, it opens into 4 valves containing 3 tiny nuts enclosed in a papery aril, whereas the 2 outer ones are ridged and the center one is flattened (3). Simple leaves feature an alternate arrangement with new growth being a bright red in colour and showing obvious stipules at leaf joints (4). Leaves of mature specimens are; up to 6 cm in length (10 cm or more on saplings and coppice shoots), mostly ovate in shape with finely toothed margins, hairless, dark green and glossy on op, paler green and dull beneath, thick and stiff in texture. Leaf apex is acute, base shape is varied from cuneate to rounded. Venation is more visible on upper leaf surface with lateral veins being straight and prominent (5). Distribution: At higher altitudes from NSW central coast to southern QLD. (See Leaf Characteristics Page for explanations on botanical terms used in descriptions.)
Australian Almond Terminalia muelleri Other names: Mueller's Damson
Under favourable conditions this medium sized tree can reach a height of about 20m in its natural habitat of monsoon and open forests close to the coastline. It is semi or fully deciduous at the end of spring with most leaves turning a reddish brown before falling, which is a helpful identification feature. The very upright, column like trunk supports far reaching and horizontally held branches (Image 1). On softer or steep sloping ground large buttress roots will form, which are covered in a hard, flaky and tesselated bark extending to the base of the trunk. Bark further up the trunk weathers to a light grey in colour with fissures showing a darker grey brown underlayer (2). The fleshy fruit (a drupe) is ovoid in shape and measures up to 20 mm in length. When fully mature the fruit is hairless, dark blue in colour with a smooth and shiny surface. It contains a single hard, cream to orange colored seed reaching 12 mm in length (3). Simple leaves with an alternate arrangement are; obovate in shape with entire margins, up to 12 cm in length, hairless, dark green on top, paler green beneath, rather dull, strong and firm in texture. Leaf apex varies from fully rounded (obtuse) to mucronate (ending in a blunt or fine tip, base shape is cuneate to more attenuate. Two swellings (glands) are located along the center vein towards the base of the leaf blade (lamina), but are not present on all leaves. Venation is clearly visible on both surfaces showing up to 7 pairs of lateral veins. Distribution: Within proximity to the coast from central to northern Qld.
Australian Indigo Indigofera australis
This native shrub is very adaptable to different environments and therefore has a very wide distribution range from high rainfall areas along the coastline to arid inland regions. It can reach a height of 2.5 m under favourable conditions with most specimens featuring a single stem (Image1). Bark is brown in colour with a firm texture and often covered in small irregular blisters (2). As this species is a member of the Fabaceae family its flowers are pea-like in appearance and colour of petals varies from mauve to more pink or purple. They measure up to 15 mm in length and often more than 20 individual flowers are held on a single raceme emerging from an axillary joint (3). The fruit is a small pod up to 50 mm long, green in colour turning black with maturity before splitting a the sides to release flat and roughly square shaped seeds (4). Pinnate compound leaves consist of 7 to more than 19 leaflets which are; 2 to 4 cm in length, mostly elliptic in shape with entire margins, hairless, dark bluish green in colour, thin with a smooth texture. Leaf apex is rounded (obtuse) with a fine tip (mucro), base shape is also obtuse. Except for mid rib venation is hardly visible (5). Distribution: Australia wide, In all types of forests. See Flower Identification and Leaf Characteristics Page for information on terms used.

Bark on older stems is a light brown in colour with a finely rough texture (2). Stems, twigs and petioles exude a milky sap when broken which is a good identification characteristic (3). Charming flowers one or 2 per stalk feature petals which are fused at the base forming a yellowish tube and split into 5 separate white petals at the top (4). Simple oppositely arranged leaves are; up to 12 cm long with entire margins which are slightly incurved and undulated, mostly oblanceolate in shape, hairless, mid green and satin glossy on top, paler and rather dull beneath with a soft and smooth texture.

Attractive female flowers a pinkish red in colour bloom in the months of August and September (3). The woody and spiky cones (held on stiff stalks) are up to 12mm long, the image shows cones still maturing (4). Branchlets with a weeping habit are fine, needle-like and reach 30 cm or more in length. Pointed teeth-like leaves are minute at less than 1 mm in length and arranged in a whorl of 7 or 8 at internodes.

Bark is hard , firm and a light grey/brown in colour with small vertical ridges and furrows on older specimens (2). Flowers are held on large panicles, measure up to 10 mm in length and 8 mm in diameter. The flower is a perianth (no petals), where sepals take the appearance of petals and form a cone-shaped tube (calyx tube) before splitting at the top (lobed) and curving outwards. Colour graduates from bright green at the base to off-white at the top. Anthers a pure white at first changing to a reddish brown colour (Picture 3 and inset). The fruit is a small nut enclosed by the remains of the calyx tube which is covered in a very sticky substance and measures up to 5 cm in length (4).
