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. Nowadays 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, where the weathered top layer is a greyish brown colour, and sheds in irregular sized plates to reveal a reddish brown fresh bark (2). The hard fruit is covered in rough prickles, up to 8 mm long and splits into 4 valves containing 3 tiny nuts. They are enclosed in a papery aril (outer layer), the 2 outer nuts are ridged and the centre one is flattened in shape (3). Simple leaves feature an alternate arrangement with new growth being a bright red colour and showing obvious stipules at leaf joints (4). Leaves of mature specimens are; up to 6 cm long (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 tessellated bark extending to the base of the trunk. Bark further up the trunk weathers to a light grey colour with fissures showing a darker grey brown under-layer (2). The fleshy fruit (a drupe) is ovoid in shape and measures up to 20 mm long. 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 coloured seed up to 12 mm long (3). Simple leaves with an alternate arrangement are; up to 12 cm long, obovate in shape with entire margins, 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 centre 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 & NT.
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). Flowers, characteristic for the FABACEAE Subfamily FABOIDEAE, are up to 15 mm long with the standard, wings and keel varying from mauve to more pink or purple in colour. 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 then 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 long, mostly elliptic in shape with entire margins, hairless, dark bluish green in colour, thin with a smooth texture. Leaflet 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. See Flower Identification and Leaf Characteristics Page for information on botanical terms used.
Australian Rhododendron Rhododendron lochiae Other names: Native Rhododendron
This very attractive shrub is one of only two Rhododendron species naturally found in Australia. It is a small terrestrial shrub or sometimes epiphyte up to1m tall and occurs as an understorey species in upland tropical rainforests. This shrub is a beautiful native ornamental plant that can be grown in frost-free areas (1). Bark is salmon coloured, weathering to grey with a flaky texture on older stems (2). Gorgeous bell-shaped flowers are up to 5cm long and held in groups of up to six individuals, appearing at the end (terminal) of young branches. The five rounded lobes are reddish pink in colour, fading to yellow, and fused into a corolla at the base (3). Simple leaves clustering at the end of branches are arranged in a whorl of 5. They are; up to 10cm long, broadly elliptic in shape with entire margins, hairless, glossy dark green on top, rather thick and rigid in texture. The straight petiole (leaf stalk) is grooved on the upper surface and up to 2cm long (4 & 5). Distribution: Tropical Far North Qld. See Flower Identification and Leaf Characteristics Page for information on botanical terms used.
Australian Round Lime Citrus australis Other names: Native Lime
This native tall shrub or small tree reaches a height of 8m and occurs in the drier parts of ecotones surrounding rainforests. It is a member of the Citrus genus and closely related to the Finger Lime (Citrus austalasica) (1). Bark is pale brown in colour with a finely rough, fissured texture (2). The rounded fruit with its dimpled surface closely resembles a lime with a strong sour taste. It reaches 4 to 5 cm in diameter and is a yellowish green colour when fully ripe. Fruit shown is still immature. (3). Branches are covered in sturdy and very sharp spines up to 3cm long (4). Simple leaves with an alternate arrangement are; up to 5 cm long, obovate or broadly elliptic in shape with entire margins, hairless, dark green, glossy on top, paler, dull beneath and emit a strong citrus scent when crushed. The leaf apex is distinctively notched (emarginate) and except for the prominent midrib venation is rather faint (5). Distribution: North from south-eastern Qld.
Australian Teak Flindersia australis Other names: Crow's Ash
The Australian Teak is a medium to tall tree species found along the east coast. It reaches a height of 40m growing on nutrient rich soils within subtropical rainforests (Image 1). Bark has a smooth firm texture and is a dark brown in colour (2). New growth can flush in pink and salmon tones before changing into a vibrant bright green (3). Pinnate compound leaves feature between 5 and 13 leaflets. Leaflets are; up to 14 cm long, ovate to elliptic in shape with entire margins, hairless, dark green, glossy on top, paler beneath, firm, smooth and scented when crushed. Leaflet apex is acute; base shape is cuneate and sometimes asymmetric (4 & 5). Distribution: From the NSW north coast to central Qld.

Due to habitat depletion this native endemic conifer species has become increasingly rare. It is able to reach a height of 20m and occurs in open Eucalypt dominated forests (Picture 1). Bark is brown in colour, weathering to dark grey with age, very rough and fissured in texture (2). Woody female cones measure up to 13mm in diameter (before opening) and consist of 6 scales, 3 larger and 3 smaller, which open widely at full maturity (3). The light brown male cones are up to 4mm long and appear at the very end of young branchlets. Male and female cones are borne on the same tree (monoecious) (4). Minute scale-like leaves are keeled (ridged), between 2 to 4mm long and appear in a whorl of three, which is characteristic for the genus (5). Distribution: Northern NSW and Qld.
Banana Bush Tabernaemontana pandacaqui Other names: Windmill Bush
The Banana or Windmill Bush is a native shrub up to 3m tall. It is found as an understorey species on margins and within subtropical and warm temperate rainforests (Image 1). Bark on older stems is a light brown in colour with a finely rough texture (2). Charming flowers feature petals which are fused at the base forming a yellowish tube and split into 5 separate white lobes at the top (3). The shape of the poisonous fruit (a follicle) relates to the common naming of this species. It contains a number of seeds covered in a reddish pulp (4). Stems, twigs and petioles exude a milky sap when broken which is a good identification feature. Simple oppositely arranged leaves are; up to 12 cm long, mostly oblanceolate with slightly incurved and undulating margins, hairless, mid green, satin glossy on top, paler and rather dull beneath, soft and smooth in texture. Leaf apex is short acuminate, base is attenuate. Fine lateral veins are visible and raised on upper surface, mid vein is raised on lower surface to only half the length of the lamina (5). Distribution: NSW mid-north coast to southern Qld.
Beach Acronychia Acronychia imperforata Other names: Fraser Island Apple, Logan Apple
Depending on conditions this handsome species is a tall shrub or small tree up to 10m in height. As the name implies this species prefers habitats in proximity to the coastline and occurs in remnants of littoral rainforests or regrowth within subtropical areas, whereas in tropical regions it is also found in upland rainforests at a height of up to 900m (1). Bark is pale brown in colour with a relative smooth texture marked by fissures and small whitish ridges at the base of older specimens (2). The brightly yellow or more orange coloured fleshy fruit (a drupe) is up to 12mm long and globose (rounded) or more obovoid (pear-shaped). Due to its extensive distribution range fruiting season stretches from winter to midsummer (3 & 4). Simple (1-foliate) leaves with an opposite arrangement are; up to 12cm long, obovate to broadly elliptic in shape with entire margins, hairless, green glossy on top, paler beneath, rather thick, leathery and only faintly scented when crushed.

Bird Lime Tree Pisonia umbellifera Other names: Miar, Sticky Bean
This interesting tree is the only species of its family in Australia and occurs in lowland subtropical and tropical rainforests. In cooler climates it reaches a height of less than 10m, whereas in tropical rainforests this species can be more than 20m tall. Mature specimens feature a sturdy trunk more than 50 cm in diameter and a compact crown (Picture 1). Bark is hard, firm and a light grey/brown in colour with vertical ridges and furrows on older specimens (2). Flowers measuring up to 10 mm long and 8 mm in diameter are borne on large panicles. The flower is referred to as a perianth (no petals), here the calyx forms a cone-shaped tube before separating at the top and curving outwards, with calyx lobes (sepals) taking on the appearance of petals. Colour graduates from bright green at the base to off-white at the top. Anthers are pure white at first changing to a reddish brown with age (Picture 3 and inset). The fruit is a small nut enclosed by the remaining calyx tube, which is covered in a very sticky substance and up to 5 cm long (4). Simple leaves show a varied arrangement changing from a cluster (pseudo-whorl) to an alternate or sometimes opposite formation. They are; up to 25 cm long (larger on saplings), mostly broad elliptic in shape with entire margins, hairless, glossy on both surfaces, paler green beneath, thick, smooth and polished in texture. Leaf apex is acute ending in a rounded point; base shape is cuneate. The strong petiole is up to 5 cm long and turns purple on mature leaves (5). Distribution: From NSW south coast to north Qld. See Flower Identification and Leaf Characteristics Page for information on terms used.
Black Apple Pouteria australis
The largest specimens of Pouteria australis occur on fertile soils within subtropical rainforests, where it can be up to 30m tall. In dryer rainforests it is a smaller tree less than 20m high (Image 1). The beautiful fluted trunk is a prominent feature on this mature specimen shown. Bark is a reddish brown colour with a finely rough texture (2). Pale green flowers are held on individual stalks up to 3 cm long (between 2 to 4 per axillary bud). Flowers are cylindrical in shape, measure about 1 cm across when fully opened and bloom in spring (3). On the mid-north coast of NSW fruit matures in summer and can then be found lying on the forest floor. The fleshy fruit (a berry) is more plum than apple shaped, up to 5 cm across and 8 cm long. Almond shaped seeds are shiny dark brown and between 3 to 5 cm long (4). Simple leaves with an alternate arrangement are; up to 15 cm long, oblanceolate to narrow obovate in shape with entire margins, hairless, dark green and very glossy on top, paler but also shiny beneath, rather thick with a firm and smooth texture. Petiole (leaf stalk) is grooved on top, between 1 to 2 cm long, and may exude a little white sap when broken (more likely on new growth). These are good identification features as the leaf venation except for mid vein is rather faint (5). Distribution: from the NSW central coast to central Qld.
