Wallum Bottlebrush Callistemon pachyphyllus Other names: Thick-leaved Bottlebrush
The Wallum Bottlebrush can be identified by the considerable thickness and unique shape of its leaves, which is reflected in the alternative common name. Under ideal conditions it may reach a height of 3m, but in exposed coastal sites it is a straggling shrub about 1m tall (Image 1). Bark is brown, weathering to grey, fibrous and flaky in texture (2). The beautiful crimson red or sometimes yellowish-green coloured flowers appear in tight groups towards the end of young branches and together form the characteristic bottlebrush shape. Individual flowers are dominated by a multitude of stamens that surround the longer style in the centre. The fruit is a woody capsule, measures up to 7mm in diameter and takes about twelve months to mature (3). Simple leaves with an alternate arrangement are crowded towards the end of branches. They are; up to 12cm long, narrowly oblanceolate (reverse lance-shaped) with entire margins, dark green on top, similar or only slightly paler beneath, thick, firm in texture and terminate in fine tips (4 & 5). Distribution: central NSW to subtropical Qld. This very ornamental species is also known under the botanical name of Melaleuca pachyphylla. See Flower Characteristics Page for explanations of definitions used.
Water Gum Tristaniopsis laurina Other names: Kanuka
This species is a common occurrence on Australia's east coast and often grows near stream banks (fresh water). Other preferred habitats include warm temperate and subtropical rainforests. It has the potential to reach a height of 30m (Image 1). Fresh bark has a very smooth texture and is grey in colour. Older bark turns brown before shedding in long strips (2). Abundant beautiful yellow flowers are up to 15mm in diameter and feature (mostly) five small rounded or more oval shaped petals. Flowering period is late spring and summer (3). The fruit is a hard capsule with 3 valves (segments) that open at the apex to disperse a large number of small papery winged seeds. Depending on climate zones fruit ripens from late summer to early winter (4). Simple leaves with an alternate arrangement are; up to 15cm long, oblanceolate (reverse lance-shaped) with entire margins, hairless, dark green on top, paler green beneath, firm and leathery in texture (5). Distribution: Victoria, NSW to central Qld. Notes: This species is used in stream bank regeneration projects, due to its hardiness and the ability to stay submerged for prolonged periods. See Leaf Characteristics Page for explanations of definitions used.

Wedge-leaved Tuckeroo Cupaniopsis wadsworthii Other names: Ducksfoot
As the common name suggests, this native Australian shrub is relatively easily identified by its distinctive wedge-shaped leaves. It prefers well-drained locations in tropical rainforests and other drier forest types, where it reaches a height of less than 4m (Image 1). Bark is grey in colour with a smooth and firm texture (2). The dark green and glossy foliage is supported by upright branches, which don't produce much lateral growth and give this shrub a characteristic appearance (3). The fruit, a capsule typical for the genus, is up to 2cm long and covered in short fine hair. It features 3 pronounced lobes, each containing a black seed covered in a bright orange aril (4). On mature specimens pinnate compound leaves consist of 2 to 4 leaflets, which are; up to 8cm long, wedge shaped with entire margins, glossy, medium thick and firm. Apex is truncated, base shape is cuneate. The mid vein is raised on the lower leaf surface and small domatia are visible along it (5). Distribution: Central to northern Qld.
Weeping Tea-tree Leptospermum brachyandrum Note: There is no official common name recorded, but Weeping Tea-Tree is widely used.
Leptospermum brachyandrum is a tall shrub or small tree up to 6m high, which will develop a drooping canopy with age. Creek banks are its preferred habitat, but the species can adapt to dryer environments (Image 1). Bark is shades of grey and sheds in rolled-up strips to expose fresh bark, which is smooth and pinkish light brown in colour (2). Flowers, characteristic for the Leptospermum genus, feature 5 white obovate (reverse egg-shaped) petals and measure less than 1cm across. Tight groups of up to 7 individual flowers appear over late spring to early summer from axillary joints towards end of young branches (3). The conical shaped fruit is crowned by five persisting sepals and measures about 5mm in diameter at the apex. Over autumn it turns hard and woody before releasing numerous tiny light brown seeds from 3 rounded valves (4). Simple leaves with an alternate arrangement are; up to 5cm long, linear to narrow lanceolate (lance-shaped) with entire margins, hairless when mature, scented when crushed and firm in texture. Leaf apex is rounded or more acute ending in a fine sharp point (mucronate), base shape is mostly cuneate. The petiole (leaf stalk) is only 1-2mm long. Faint elliptical venation is visible on the lamina (5). Distribution: From NSW mid-north coast to northern Qld. See Flower Identification and Leaf Characteristics Page for information on terms used.
White Beech Gmelina leichhardtii
This stately and attractive tree inhabits subtropical and littoral rainforests, where it attains a height of up 40m (Image 1). Bark at the base of older trunks becomes rough, scaly and fissured. It is mottled grey in colour and firm in texture (2). The vivid blue coloured fruit (a drupe) is roughly globe-shaped and reaches up to 25mm in diameter. It is fleshy and contains a single brown and hard-shelled seed (3). Growing buds, petiole and twigs are densely covered in fine rusty brown hair (4). Simple leaves with an opposite arrangement are; up to 20cm long with nearly entire margins, (compared to the strongly toothed margins of juvenile leaves, shown), ovate in shape, dark green glossy, hairless except for veins on upper surface, paler green, hairy beneath, firm and slightly rough in texture. Venation is clearly visible with the centre vein being strongly raised on lower leaf surface. Petiole (leaf stalk) is up to 25mm long (5). Distribution: From the south coast of NSW to central Qld.

The genus Pouteria was reclassified as Planchonella (APC) (Image 1). Bark is greyish brown on the outer surface, firm and marked by small fissures showing the brown underlying fresh bark (2). The fleshy fruit contains a single seed and is classified as a berry. Colour of the fruit changes from green to yellow, than red and finally black at full maturity. It is reverse egg-shaped (obovoid) and reaches a length of about 2.5cm (3 & 4). Simple leaves with an alternate arrangement are; up to 17cm long, obovate (reverse egg-shaped) with entire margins, dark green, glossy on upper surface, silvery or brownish green beneath, strong and firm in texture. Lateral veins are prominent on both leaf surfaces. The petiole (leaf stalk) is up to 2cm long and, characteristic for the genus, may exude a small amount of milky sap when broken (4 & 5). Distribution: northern Qld. See also: Yellow Plumwood Planchonella myrsinifolia below on this page.

Yellow Carabeen Sloanea woollsii
This majestic very tall tree species can grow to more than 50m in height and is often part of the highest canopy in subtropical rainforests. It has been extensively logged for its valuable timber. The specimen shown in picture 1 is being overtaken by a Strangler Fig (Ficus watkinsiana) (Pictures 1 & 2). Older trees develop large sail-like (plank) buttress roots. Bark is grey brown and finely rough at the base, turning to grey with a smoother texture further up the trunk (3). The fruit (a capsule) is covered in sturdy spikes up to 20mm long. It features 2 valves (segments), each containing a seed covered in a yellow or reddish aril (4). Simple (1-foliolate) leaves are; up to 16cm long, elliptic to lanceolate (lance-shaped) with toothed margins, hairless, smooth and strong in texture. Young shoots and petioles (leaf stalks) are covered in fine hair. On the lower leaf surface hairy bristles (domatia) are visible along the mid rib at junctions of lateral veins (5). Distribution: from the mid-north coast of NSW to central Qld. See also: White Carabeen (Sloanea langii), above on this page and Maiden's Blush (Sloanea australis) Page 7.
Yellow Necklacepod Sophora tomentosa Other names: Silver Bush
This eye-catching plant colonises the first sand dunes above the high tide mark and is able to flourish on fresh sand with a high salt content. It is a sturdy tall shrub that reaches a height of 5m. This species belongs to the Pea & Bean Family (FABACEAE/FABOIDEA), members of which have the ability to form symbiotic relationships with bacteria and thereby fix atmospheric nitrogen in the soil. The specimen shown is growing on the margins of coastal (littoral) tropical rainforest (Photo 1). Bark on older stems is brown, firm and marked by prominent blisters (2). The raceme is up to 50cm long and produces individual bisexual flowers, which mature from the base, over an extended period of time. Flowers are bright yellow and including the hairy calyx (base) up to 30mm long. They feature a standard (large top petal), wings (two side petals) and a keel (two fused petals surrounding the female carpel and male stamens), these modified petals are typical for the family (3). The common name refers to the fruit having a necklace like appearance. The abundantly produced pods are finely hairy and reach a length of 16cm (4). The pinnate compound leaf consists of up to 19 leaflets with an opposite arrangement and a terminal leaflet is always present. Leaflets are; up to 6cm long, ovate (egg-shaped) or broadly elliptic with entire margins, dark green above (when mature), greyish green and silvery hairy beneath, smooth and soft in texture. Scraping the pods or bark of young branches emits a strong bean scent, but all parts of the plant are reported to be poisonous (5). Distribution: Close to the beach, from the mid-north coast of NSW to northern Qld and NT. Note: Sophora tomentosa is listed as an endangered species in NSW. It is an attractive ornamental species for sandy soils.
Yellow Plumwood Planchonella myrsinifolia Other names Blunt-leaved Coondoo
The Yellow Plumwood or Blunt-leaved Coondoo is a small native tree species growing to a height of 15m and inhabits different forms of rainforests (Image 1). Bark is brown in colour with a rough and grainy texture, featuring numerous fine longitudinal ridges (2). Yellowish green and cylindrical shaped flowers measure only up to 3mm wide by 7mm long. They are supported by solitary stalks less than 1cm long (3). Young stems, flower stalks and petioles (leaf stalks) are covered in very fine and short hair. Developing fruit is shown to the bottom right in the image (4). Simple neatly alternately arranged (two-ranked) leaves are; up to 10cm long, elliptic to oblanceolate (reverse-lance-shaped) with entire margins, dark green with a satin sheen on top, paler underneath, medium thick, strong, somewhat leathery and on this specimen mostly hairless. Apex is bluntly pointed, leaf base shape is attenuate. Mid vein is raised on lower surface and hairy at the base, otherwise venation is rather faint (5). Distribution: NSW central coast to southern Qld. See also: Black Apple (Planchonella australis) Page 1.
Yellow Satinheart Bosistoa transversa
This elegant small to medium sized tree species reaches a height of 15m and occurs in warmer subtropical rainforests (Image 1). Bark is brown in colour (grey patches are lichen), and features small longitudinal fissures and some blisters (2). White to cream coloured flowers are borne on large panicles emerging at the end of branches. Flowers feature 5 ovate petals and 10 prominent stamens with solid flattened filaments and brown anthers (3). The fruit is a small woody follicle less than 1.5cm long with distinct horizontal ribs showing on the surface (4). Compound leaves consist of two to three leaflets or are sometimes reduced to a single leaf. Leaflets are; up to 14cm long, broad elliptic to lanceolate (lance-shaped) with entire margins, hairless, rather thick and strong in texture. Venation is very prominent on lower leaflet surface (5). Distribution: northern NSW to central Qld.
