Macaranga Macaranga tanarius Other names: Nasturtium Tree, David's Heart, Heart Leaf, Bullocks Heart, Blush Macaranga
The Macaranga is a tall shrub or small tree less than 10m in height, but some specimens competing for sunlight within rainforests may reach 12 - 15m. It prefers better light conditions at forest margins or in regrowth areas after logging. It is used in landscaping for its manageable size, hardiness to full sunlight, attractive foliage and flowers (Image 1). Mature trees feature a stout, often twisted and irregular trunk which is covered in a firm and brown coloured bark (green, pink and white colours are caused by mosses and lichen). The surface shows small wart like bumps and horizontal scars left by detached branches (2). Unusual yellowish green flowers are held on long panicles with dioecious trees bearing male or female flowers only. The size of the frilled bracts surrounding a number of individual flowers is more than 1 cm in length, indicating that a female inflorescence is shown in the picture (3). Simple leaves with an alternate arrangement are; up to 25 cm long, rounded in shape with entire margins, mid-green, hairless on upper surface, grey-green and finely hairy beneath (more so on younger leaves) with a soft texture. Leaf apex is mucronate (rounded with a short sharp point), base shape is rounded. The strong petiole measures up to 30 cm in length and is attached towards the centre of the leaf blade (lamina). The palmate venation is very noticeable on both leaf surfaces (4&5). Distribution: From NSW north-coast to northern Qld.
Macleay Laurel Anopterus macleayanus
The Macleay Laurel is an attractive and unusual under storey tree species found in different types of rainforests. In undisturbed subtropical rainforests it can reach a height of 15m or more (Image 1). Mature specimens feature a distinctive bark which is red brown in colour and covered in warts (2). Beautiful white flowers are up to 10 mm in diameter and bloom in early spring (3). The fruit is a pointed capsule measuring up to 4 cm in length, which is beige in colour and contains more than a dozen flat winged seeds about 2 cm long (4). The growing bud and fleshy petioles on young shoots are coloured bright red and are good identification characteristics (5 inset). Large simple leaves arranged in a whorl of up to 5 leaves below the growing bud are; up to 35 cm long, mostly oblanceolate in shape with finely toothed margins, hairless, dark green and glossy on top, paler and glossy beneath with a smooth, firm texture. Leaf apex is acute, base shape is acuminate. Petiole up to 30 mm long changes colour to green on older leaves (5). Distribution: NSW mid-north coast to Qld. See Flower Characteristics Page and Leaf Characteristics Page for information on terms used.
Maiden's Blush Sloanea australis Other names: Blush Alder
This beautiful tree grows to a height of up to 30m with buttress roots developing on older specimens and occurs within subtropical rainforests (Image 1). Bark on mature trees is dark brown in colour with furrows and blisters (2). Stunning sprays of white flowers with yellow centres bloom in spring (3). The fruit capsules ripening in late summer contain up to three seeds covered in a red aril. Old seed capsules found around the base of this tree can help in identification of this species (4). Simple (1-foliolate) leaves with an alternate arrangement are; up to 20 cm long, mostly obovate in shape with toothed or crenate margins, dark green and glossy on top, lighter green below, hairless, strong and firm in texture. Leaf apex is short acuminate ending in a blunt point; base is tapering into a rounded end. Petiole is up to 30 mm long and features a pronounced pulvinus. Mid rib, laterals and net veins are pronounced and raised on lower leaf surface (5). (See Leaf Characteristics) Distribution: From the south-coast of NSW to subtropical Qld. Young shoots and petioles are not covered in hair compared to its relative the Yellow Carabeen (Sloanea woollsii) Page 12.
Maiden's Wattle Acacia maidenii
The Maiden's Wattle is a common and widespread native tree species reaching a height of up to 20m under favourable conditions. It can be a tall multi-stemmed shrub in dry and exposed environments (Picture 1). Bark is a greyish brown in colour and rather stringy and fissured on older specimens (2). Attractive flower spikes up to 8 cm long feature bright yellow buds opening into white and cream coloured flowers which turn a pale yellow colour when maturing (Pictures 3 & 4). Simple leaves (phyllodes) with an alternate arrangement are; up to 16 cm long with entire margins, mostly narrow elliptic in shape and sometimes curved, mid-green and rather dull on top, similar below, hairless with a firm and slightly stiff texture. Leaf apex is acute ending in a fine point, base shape is cuneate. Venation is rather faint with up to 5 longitudinal main veins showing (5). Distribution: Vic., NSW & Qld. See Leaf Characteristics Page for explanations of definitions used.
Marbled Baloghia Baloghia marmorata Other names: Jointed Baloghia
The Jointed or Marbled Baloghia Baloghia marmorata is a rare native shrub or small tree below 10m in height occurring in subtropical rainforest (Image 1). Bark is cream to light brown in colour with a firm texture and fine fissures (2). Clusters of white flowers are held on stems up to 18 cm in length together with two opposite leaves normally less than 10 cm long (3). 3 or 4 simple leaves are clustered below the growing bud, changing to an alternate arrangement when maturing (4). Leaves are; up to 15 cm long with entire margins, long elliptic to oblanceolate in shape, glossy on both surfaces, hairless, medium thick and leathery. Apex is mostly short acuminate, base is attenuate in shape. Petiole is up to 5 cm long, slender but strong and stiff. The mid vein is raised on lower surface in the bottom half of the leaf only (5).

Milk Bush Neisosperma poweri Other names: Red Boat Tree
As an under-storey species within subtropical rainforests this tall shrub or small tree can reach 10m in height under favourable conditions (Image 1). Bark is light brown in colour and densely marked by small blisters (lenticels) (2). Attractive white flowers are held on small panicles appearing at the very end of young branches. They bloom over mid to late summer and measure up to 1 cm in length (3). Broken petioles (leaf stalks) and branchlets exude a generous amount of white latex turning sticky on exposure (4). Leaves with an opposite arrangement (or irregular in whorls of 3) are; up to 12 cm long on mature specimens, obovate in shape with entire margins, dark green on top, light green beneath, hairless and smooth in texture. Lateral venation is faint all over but more visible on the upper surface, whereas the mid rib is pronounced on both surfaces (5).

Murrogun Cryptocarya microneura Other names: Brown Jack
This native species is a regular occurrence in warm temperate and subtropical rainforests. It can survive low intensity fires when growing in drier open eucalypt dominated forests. Under good light conditions it is able to reach a height of 20m or more, but beneath a dense rainforest canopy it is often reduced in size (Image 1). The trunk on mature specimens can be fluted or is often crooked. Bark on young trees is furrowed with a soft, corky texture and grey in colour changing to brown with a more scaly texture on mature trees (2). Flowering in some years can be profuse turning the whole tree to a creamy, yellow colour. Individual flowers measure up to 5 mm across when opened with no visible distinction between the calyx and the corolla. They are held on large and intricately branched panicles appearing towards the end of young branches and flower over spring (3). The fruit (a drupe) turns from green to black with full maturity and shows a finely wrinkled surface texture. It is rounded to slightly more oval in shape with a pointed tip at the apex and measures up to 12 mm in length (4). Simple leaves with an alternate arrangement are; up to 12 cm long, mostly elliptic in shape with entire margins, hairless, dark green glossy on top, paler, whitish green below, firm and slightly leathery in texture. Young leaves, especially on juvenile trees have a white waxy covering on their underside. Leaf apex is acuminate ending in a rounded tip, base is wedge shaped (cuneate). Midrib is yellowish or whitish in colour and a bit crooked, up to 6 or 7 mostly uneven pairs of lateral veins also yellowish or whitish in colour (5). Distribution: From NSW south coast to central Qld. See Flower Characteristics Page and Leaf Characteristics Page for information on terms used.
