Forest Oak Allocasuarina torulosa

Forest Oak Allocasuarina torulosa Other names: Mountain Forest Oak, Rose Sheoak
This native tree is found in tall forests adjacent to different rainforest types. It is often an understorey species beneath tall Eucalypts and under favourable conditions can reach a height of 30m. This species is dioecious, meaning male and female flowers are borne on different trees (Photos 1 & 2). Bark is brown in colour, rough with deep fissures and a hard texture, becoming softer after prolonged rain (3). Woody cones produced by female trees are up to 3cm long and contain numerous small brown winged seeds (4). The male flowers are borne on the very end of branchlets. Minute scale-like leaves appear in a whorl of four (5). Distribution: NSW south coast to northern Qld.

Geebung (species) Persoonia rufa

Geebung (species) Persoonia rufa
The Geebungs are an interesting and diverse group (genus: Persoonia) consisting of about 100 species, all of which are endemic to Australia, i.e. exist only in Australia. They are found in all states/territories and inhabit different environments ranging from semi-arid regions to rainforests. Geebungs are shrubs or small trees, known for their edible fleshy fruits (drupes), which characteristically feature a persistent hardened flower style at the apex.
There is no common name recorded for this species and it has been elevated from a subspecies (P. corniflora ssp. C sensu) to species level (P. rufa). It is a multi-branching upright shrub reaching a height of about 2.5m that is found in heaths, woodlands and open forests at higher altitudes (1). Bark on older stems is grey, firm and finely rough due to scattered blisters and small fissures. Young branchlets are brown and covered in short, soft and whitish hair (2). The fleshy fruit (a drupe) is broadest around the middle (ellipsoid) and turns yellowish green at maturity. It is up to 15mm long, finely hairy and topped by the persisting flower style (3). Simple leaves with an alternate arrangement are; up to 8cm long, elliptical or narrow lanceolate (lance-shaped) with entire (in-rolled) margins, sparsely hairy or hairless when mature, dark green on top, yellowish green beneath, thick and firm in texture. The brown and hairy petiole (leaf stalk) thickens at the base and is 2-3mm long. Venation is more visible on upper leaf surface (4 & 5). Distribution: confined to the northern tablelands of NSW (Gibraltar Range).

Geebung (species) Persoonia stradbrokensis

Geebung (species) Persoonia stradbrokensis
There is no official common name recorded for this species, but some sources list it as Broad-leaved Geebung. Confusingly, this common name is assigned to the very similar Persoonia levis (see Page 2). The distribution range for both species only overlaps in a small area of the mid-north coast of NSW. The distribution range of Persoonia levis stretches south from the mid-north coast of NSW to Victoria, whereas P. stradbrokensis exists north from the mid-north coast of NSW to subtropical Qld.
Persoonia stradbrokensis is a tall shrub or small tree reaching a height of 6m that inhabits dry open Eucalypt dominated forests and heath lands, east of the Great Dividing Range (Image 1). Bark at the base of older trunks is brown and fissured, whereas bark of P. levis is dark grey/black, flaky and scaly (2). The bright yellow floral tubes are up to 12mm long, finely hairy and split into 4 pointed lobes at the apex when maturing. They appear along terminal branchlets (young twigs) that are densely covered in fine hair. Branchlets continue growing and produce further leaves. Flower stalks (pedicels) are up to 4mm long and also hairy (3). The fruit, a drupe, is hairless, yellowish green when mature and up to 2cm long. The translucent and edible fruit flesh becomes very sticky on exposure and surrounds a hard-shelled seed. A prominent persisting flower style is present at the top of the fruit (4). Simple leaves with an alternate arrangement are; up to 11cm long, broadly elliptic, somewhat convex, nearly the same colour green on both surfaces, hairy when young, hairless when mature, smooth and firm in texture. Leaf apex can be asymmetric and a terminal small tip is visible. Venation is indistinct. Distribution: from the mid-north coast of NSW to south eastern Qld.

Giant Stinging Tree Dendrocnide excelsa

Giant Stinging Tree Dendrocnide excelsa
This impressive tall rainforest tree has the potential to reach a height of 45m and a trunk up to 5m in diameter. It has a fast and upright growth habit and occurs in subtropical rainforests and regrowth areas (Photo1). Bark is fairly soft in consistency and coloured grey to brown, but is often covered by mosses and lichen (2). Foliage on mature trees is frequently damaged by insects, whereas leaves of sapling trees are less affected. Leaves of juvenile specimens are up to 35cm long (3 & 4). Very painful stinging hairs cover the underside and especially the veins of the leaf. Simple adult leaves with an alternate leaf arrangement are; up to 20cm long, mostly rounded in shape with entire or toothed margins. The prominent petiole can be more than 10cm 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.

Golden Pea Daviesia arborea

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 (FABACEAE), measure up to 5mm across and are a bright yellow colour (3). The fruit is a flattened pod, which is less than 1cm long and up to 5mm wide, a dried sample is shown (4). Simple leaves (phyllodes) with an alternate arrangement are; up to 20cm long, rarely more than 1cm 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

Golden Penda Xanthostemon chrysanthus Other names: Johnstone River Penda
The Golden Penda is widely used as an ornamental tree along Australia's East-Coast, but is in fact endemic to far 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 will rarely reach more than half that height (Picture 1). Bark is a reddish brown colour, firm in texture and marked by irregular vertical ridges (2). Beautiful flowers feature 5 rounded and bright yellow petals up to 8mm long. The prominent filaments (of stamens) are up to 30mm long and topped by small brown (when mature) anthers. Stamens are arranged in a circle surrounding the visible and more green coloured ovary in the centre. The style with an inconspicuous stigma exceeds the length of stamens (3). The fruit is a hard spherical capsule up to 15mm in diameter, which splits at the apex to release a large number of flattened seeds. It is seated in the remaining calyx (flower base) (4). The dense foliage concentrates towards the end of young branches. Leaves with an irregular whorl arrangement are; up to 18cm long, elliptic or slightly more lanceolate/oblanceolate (lance or reverse lance-shaped) with entire margins, dark green, glossy on top, paler green beneath, hairless and firm in texture. The stout petiole (leaf stalk) is up to 15mm long. Fine reticulate venation is visible (5). Distribution: Naturally only occurring on the Cape York Peninsula, North Qld.

Golden Tip Goodia lotifolia

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 under shady conditions can be reduced to a single lamina (leaf blade) up to 6cm long (3 & 4). When receiving more sunlight leaflets are considerably smaller, only up to 3cm long, broadly oblong or ovate (egg-shaped) 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 the Pea & Bean Family FABACEAE, Subfamily FABOIDEAE.

Grease Nut Tree Hernandia bivalvis

Grease Nut Tree Hernandia bivalvis
This small to medium sized native species reaches a height of up to 20m and develops a lush canopy. It originates in dryer forms of rainforests, but is an uncommon occurrence in this natural habitat (Photo 1). Bark is light to dark olive green in colour and despite burls and small fissures has a rather smooth texture (2). A very attractive flowering display takes place over late spring into early summer. Individual flowers are borne on tightly packed panicles that emerge towards the end of young branches. Flowers measure up to 3cm 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 4cm in diameter, the persistent and overlapping bracts change to orange/red with full maturity (4). Simple leaves with an alternate arrangement are; up to 10cm long, ovate (egg-shaped) with entire in-rolled margins, hairless, dark green, glossy on top, strong and fairly stiff in texture. Leaf apex is short acuminate ending in a blunt point, base shape is rounded. Reticulate venation is very prominent on both leaf surfaces, with small bristle-like domatia showing in lateral vein axils (5). Distribution: South eastern Qld. Note: Often planted as an ornamental tree, but now increasingly rare in its natural range.

Green-leaved Rose Walnut Endiandra muellerii

Green-leaved Rose Walnut Endiandra muellerii subsp. muellerii  Other names: Mueller's Walnut
Within fertile subtropical rainforest, the Green-leaved Rose Walnut or Mueller's Walnut can reach a height of up to 35m, but in littoral and warm temperate forms of rainforests it is often encountered as a smaller tree. It is very common as a rainforest regeneration tree and found as one of the first species to recolonise adjoining tall forests (Photo 1). Mature specimens feature a flanged and buttressed trunk. The bark is hard and rather rough in texture with small vertical ridges and scattered rounded depressions; colour is a greyish brown (2). Small pink flowers a held on drooping panicles and blossom in late spring to early summer (3). Attractive new leaf growth flushes in a deep rose colour, changing to salmon and light green with maturity. Mature simple leaves with an alternate arrangement are; up to 11cm long, elliptic to broad elliptic in shape with entire and sometimes undulating margins, hairless, dark green and semi glossy on top, slightly paler, but also shiny beneath, smooth and leathery in texture. Leaf apex is acute to short acuminate ending in a blunt point, base shape is cuneate or rounded. Petiole (leaf stalk) is up to 1cm long. Centre vein and laterals are noticeably raised on lower leaf surface and net veins are visible. Domatia are shallow pockets (often more inconspicuous than the domatium shown in the red circle). They are not present on every leaf. For identification check a number of leaves on different branches (Photos 4 & 5). Distribution: From NSW central coast to Qld.

Grey Handlewood Aphananthe philippinensis

Grey Handlewood Aphananthe philippinensis Other names: Native Elm, Axe-handle Wood
This native tree prefers moist environments such as subtropical or tropical rainforests and streams banks. When growing beneath taller rainforest trees, it may only reach 10m, but under ideal conditions it is able to attain a height of more than 25m (Photo 1). Buttress roots develop on older specimens and the trunk is often misshaped and fluted. The rough bark is grey to more brown in colour and covered in longitudinal rows of small blisters (pustules) (2). Separate female and male (shown) flowers are borne on the same tree (monoecious). Male flowers are less than 5mm long. Flowering period is over spring (3). The fruit is a fleshy drupe, changing from green over yellow to black at full maturity. It is egg-shaped (ovoid) or more olive-shaped (ellipsoid) and up to 1cm long. The remnant forked (bifid) flower style persists at the apex of the fruit maturing in late summer (4). Adult simple leaves feature an alternate arrangement and are; between 3 to 10cm long, mostly ovate (egg-shaped) with up to 6 sharp, spiny teeth along either side, hairless, rather glossy, stiff and tough in texture. Prominent mid and lateral veins are impressed on the upper and strongly raised on the lower leaf surface (5). Distribution: from the NSW mid-north-coast to northern Qld.

Grey Mangrove Avicennia marina

Grey Mangrove Avicennia marina Other names: White Mangrove
This widespread Mangrove colonises muddy banks, below the high tide and above the low tide mark (intertidal zones), within estuaries and along river banks (further inland) that are affected by tidal forces. The Grey Mangrove has the potential to reach a height of 15m in tropical areas, whereas in temperate climates it is likely to be a tall shrub. Masses of distinctive upright and stick-like aerial roots (pneumatophores) are exposed at low tide and then assist in the uptake of oxygen (1). Bark is shades of grey in colour and towards the base of older trunks becomes flaky and finely fissured (2). The irregular rounded or more elongated and somewhat flattened fruit turns yellowish green when fully mature and is covered in short fine hair. It is up to 4cm long (diameter) and consists of a thin skin enclosing a single seed, which germinates while the fruit is still attached to the tree. Two seedling leaves (cotyledons), the stem and the developing root system are visible (3 & 4). Mature simple leaves feature an opposite arrangement and vary in shape from elliptic to broadly lanceolate (lance-shaped) or sometimes oblanceolate (reverse lance-shaped). They are; up to 9cm long with entire margins, hairless, dark green, glossy on top, greenish grey or silvery grey and finely hairy beneath, thick and leathery in texture. Leaf apex is acute ending in a blunt point, base shape is cuneate (wedge-shaped). The strong petiole (leaf stalk) turns yellowish on older leaves and is up to 2cm long (5). Distribution: southern Vic., NSW to northern Qld. (Also in NT, WA and SA). 3 subspecies of Avicennia marina are recognised. Despite the superficially similar appearance of many Mangroves, species belong to a number of different flowering plant families.

Grey Myrtle Backhousia myrtifolia

Grey Myrtle Backhousia myrtifolia Other names: Ironwood, Carrol
The Grey Myrtle, also called Carrol or Ironwood, is a widespread native tree species that is found in different forest types and under favourable conditions can reach a height of up to 20m (Photo1). Bark on older specimens is; very hard, rough, fissured and depending on conditions more grey or brown in colour (2). Attractive flowers are pure white in colour and measure up to 15mm in diameter (3). The fruit still resembles the shape of a flower, as the calyx (base) of the original flower enlarges and partly encloses the ripe fruit (4). Growing buds, immature leaves and young stems are finely hairy. Adult simple leaves with an opposite arrangement are; 3 to 6cm long, broad elliptic to ovate in shape with entire and slightly incurved margins, hairless, dark green and glossy on top, paler beneath, thin but firm in texture and scented when crushed. Leaf apex is short to long acuminate ending in a fine point, base shape is mostly rounded. Mid vein is raised on both surfaces, straight and numerous lateral veins are more visible below (5). Distribution: NSW south coast to central Qld.

Grevilleas

The genus of Australian Grevilleas is well known for its unusual and amazing flowers, leading to the creation of many cultivars used in today's gardens and landscaping. Growth habit can range from a small woody shrub to a tall tree, as is the case with the Silky Oak Grevillea robusta. Leaf shapes and arrangements are very varied and good identification features. The prominent flower styles are retained to the fruiting stage and are characteristic for the genus. The typical fruit is a follicle, which hardens with maturity and opens to release flattened seeds.
