Fuchsia Heath Epacris longiflora
This very eye-catching shrub flowers for most time of the year and is extremely adaptable to climatic conditions. It reaches a height of 2m and frequently inhabits headlands, coastal heath, open woodlands and tall forests. The specimen shown was observed at cliff face, bordering cool temperate rainforests at an altitude above 1400m, receiving freezing winds and snowfalls in winter (1). Bark is brown in colour, weathering to grey with a rough, fibrous texture (2). The gorgeous tube-shaped flowers are up to 4cm long and their natural colour ranges from deep pink to red or white. The corolla (flower tube) splits into 5 pointed and pure white lobes at the apex (3). Young branchlets are covered in long white matted hair (4). Simple leaves are spirally arranged around drooping branches. They are; 7 to 15mm long, broadly ovate in shape, dark green on both surfaces, stiff and terminate in a sharp, prickly tip (5). Distribution: Central coast of NSW to southern Qld.
Furry Nightshade Solanum hapalum
This small shrub rarely attains more than 1m in height and is found in a range of habitats, ranging from different rainforest types to drier open tall Eucalypt forests (shown). It has an upright habit and is often found in small groups (1). Bark on older specimens is slightly rough, sometimes scaly in texture and an olive green to more brown in colour (2). Beautiful flowers reach on average 15 mm in diameter and show 5 fused petals being a rather uniform mauve to more purple in colour. Flowering takes place over spring (3). The fruit turns bright red in colour when fully mature and is globular in shape. It measures less than 1 cm across with the hairy sepals of the remaining flower calyx (base) partly covering the fleshy berry (4). Simple leaves with an alternate arrangement are; ovate in shape with entire margins, up to 8 cm long, green with a grey hue on top, grey to yellowish green beneath, densely covered in hair on both surfaces and softly furry in texture. Leaf apex is acute, base shape varies from rounded to cordate and is often asymmetric. The petiole (leaf stalk) is very hairy and reaches up to 3 cm in length. Hairy veins are raised and more obvious on lower leaf surface (5). Distribution: From NSW south coast to southern Qld.
Giant Stinging Tree Dendrocnide excelsa
This very tall rainforest tree species has a fast and upright growing habit and occurs in subtropical rainforests (Photo1). Bark is fairly soft to the touch and coloured grey to brown, but is often covered by mosses and lichen (2). Foliage on mature trees is frequently damaged by insects, whereby leaves on sapling trees are less affected. Leaves in juvenile specimens are up to 35 cm long (3 & 4). Very painful stinging hairs cover the underside especially the veins of the leaf. Simple adult leaves with an alternate leaf arrangement are; up to 20 cm long, mostly rounded in shape with entire or toothed margins. The prominent petiole is sometimes more than 10 cm long (5). Distribution: South coast of NSW to central Qld. Note: Even half decayed leaves lying on the forest floor will still have a stinging effect. See also Shiny-leaved Stinging Tree Dendrocnide photinophylla Page 9.

Leaf apex and base shape is rounded (5). Distribution: Tropical Qld.
Golden Pea Daviesia arborea Other names: Golden Pea Tree, Bitterleaf Pea
When not in flower this species can easily be mistaken for an Acacia species (Wattle Tree), as the foliage is very similar in appearance. It is an understorey shrub or small tree rarely reaching more than 10m in height. It prefers to grow in tall, often Eucalypt dominated forests, where it plays an important role enriching nutrient poor soils (Image 1). In identification, the soft corky and deeply furrowed (grooved) bark differentiates the Golden Pea from similar Acacia species. Bark is brown in colour (2). The small flowers typical for the Pea & Bean Family measure up to 5 mm across and are bright yellow in colour (3). The fruit is a flattened pod, which is less than 1 cm long and up to 5 mm wide, a dried sample is shown (4). Simple leaves (phyllodes) with an alternate arrangement are; up to 20 cm long, rarely more than 1 cm wide, mostly linear in shape with entire margins, hairless, dark green on top and paler beneath. Slightly irregular parallel veins are faintly visible (5). Distribution: Northern NSW to Qld.
Golden Penda Xanthostemon chrysanthus Other names: Johnstone River Penda
This Golden Penda is so widely used as an ornamental tree that it might be mistaken for an exotic species, but is in fact endemic to northern Qld. In its natural habitat of low and upland tropical rainforests it can reach a height of 20m, whereas planted in an open position it rarely reaches more than half that height (Picture 1). Bark is a reddish brown colour, firm in texture and marked by irregular vertical ridges (2). The fruit is a hard spherical capsule up to 15 mm in diameter that splits at the apex to release a large number of flattened seeds. It is seated in the remaining calyx and a persistent style at the apex is often present (3). The dense foliage concentrates towards the end of young branches. Leaves with a irregular whorl arrangement are; up to 18 cm long, elliptic or slightly more lanceolate/oblanceolate in shape with entire margins, dark green, glossy on top, paler green beneath, hairless and firm in texture. The stout petiole (leaf stalk) is up to 15 mm long and fine reticulate venation is visible (4 & 5). Distribution: Naturally only occurring on the Cape York Peninsula, North Qld.
Golden Tip Goodia lotifolia var. pubescence Other names: Clover Bush, Yellow Pea
This widespread shrub is able to adapt to the low light conditions found under a rainforest canopy (shown), but is more abundant in transition zones and tall open forests. Under favourable conditions it can attain a height of up o 4m. Two different variations G. lotifolia var. lotifolia, with nearly hairless leaves and stems, and G.lotifolia var. pubescence (shown), which is densely hairy, are recognised (Picture 1). Bark is firm and brownish in colour (2). Trifoliate compound leaves are characteristic, but can be reduced to a single lamina (leaf blade) up to 6 cm long in shady conditions (3 & 4). When receiving more sunlight leaflets are considerably smaller, only up to 3 cm long, obovate in shape with entire margins, thin and soft in texture. Leaflet apex is rounded with a very fine tip (mucronate); base is wedge-shaped (4 & 5). Distribution: Tas, Vic, NSW and southern Qld. This species with bright yellow flowers belongs to Pea Family Fabaceae Subfamily Faboideae.
Grease Nut Tree Hernandia bivalvis
The Grease Nut Tree Hernandia bivalvis is a small to medium sized native tree species with a lush canopy reaching a height of up to 20m. It prefers dryer forms of rainforests and now is uncommon in its natural habitat (Photo 1).

A very attractive flowering display takes place over late spring into early summer with individual flowers being held in tightly packed panicles emerging towards the end of young branches. Flowers measure up to 3 cm in diameter and feature mostly eight pure white petals and four prominent stamens topped by red anthers. Bracts (part of a flower appearing to be leaf like) surround and protect the ovary (3). The fruit turns black when ripe and is about 4 cm in diameter, the persistent and overlapping bracts change to orange/red in colour with full maturity (4). Simple leaves with an alternate arrangement are; up to 10 cm long, ovate in shape with entire in-rolled margins, hairless, dark green, glossy on top with a strong a fairly stiff texture. Leaf apex is short acuminate ending in a blunt point, base shape is rounded.
