Characteristics

Understorey forest trees up to 12 m tall, or smaller shrubs; trunk with light red wood, covered with smooth grey bark, flaking irregularly exposing brown patches; crown small, with ascending grey and brown mottled branches which are irregularly ridged with grey raised lenticels. Leaves semi-persistent or deciduous, shed in spring or during a period of drought; lamina deep green, variable, broadly to narrowly elliptic, 5-10 cm long, 2-3 cm broad, apex rounded to acute, base truncate, margin nearly smooth or with some shallow teeth to sharply serrate, venation distinctly reticulate, leathery; stipules intrapetiolar, fused. Flowers scented, arranged in compound, complex, many-flowered usually erect panicles on well developed, mostly leafless branchlets to a reduced subcorymbose fascicle with 4-8 flowers on a very short spur. Sepals 5, ovate-convex, c. 7 mm long, green; enlarged, dark red and reflexed at anthesis and in fruit. Petals 5, obovate-cuneate, 12 mm long, yellow. Stamens c. 30, with filaments about as long as biporose anthers. Carpels 5, reniform; styles completely united or free apically; stigmas capitate. Drupelets reniform, 10-15 mm long, black. Flowering in spring.
More
Understorey tree or shrub, 1.5-12.0 m high; wood light red. Leaves shortly petiolate, deep green, broadly to narrowly elliptic, base truncate, apex acute, margins nearly smooth to sharply serrate, veins distinctly reticulate; stipules intrapetiolar, fused. Sepals 5, ovate-convex, green, persistent, becoming enlarged in fruit, dark red, reflexed. Petals 5, obovate-cuneate, yellow, fugaceous. Stamens ± 30, free; filaments as long as biporose anthers. Carpels 5, 1-ovulate; styles completely united or upper ends free, recurved; stigmas capitate. Flowering time Aug.-Nov. Fruit hard, black and shiny drupelets.
Leaves petiolate; lamina 2·4–7·5 (12) × 1–3 cm., oblong to elliptic or oblanceolate, acute to obtuse or rounded (often mucronate) at the apex, with margin entire or densely but shallowly serrate, narrowly cuneate to truncate or subcordate at the base, chartaceous to sub-coriaceous, with numerous (c. 20–40) lateral nerves and densely reticulate tertiary venation prominent on both sides; petiole (1) 1·5–2·5 (3) mm. long, slender or rarely somewhat swollen.
Shrub or tree (1·5) 3–9 (12) m. high, with bark very smooth, pale grey and peeling in papyraceous layers to reveal red patches; branches slender, ascending, greyish-brown at first, becoming reddish-purple, not peeling.
Flowers 3–7 (11), in a simple (very rarely compound at the base) terminal erect raceme 0·5–1·5 cm. long; pedicels (0·9) 1·5–2·5 (3) cm. long in fruit, articulated at the base or in the lower 1/4.
Semideciduous tree with flaking bark to 12 m. Leaves elliptic, finely toothed. Flowers several in clusters or panicles, scented, yellow.
Stamens with anthers 1·5–2 (3) mm. long, equalling or to 1/3 as long as the filaments, straight, dehiscing by apical pores.
Sepals 4–6 (6·5) mm. long in flower, elliptic-oblong, rounded, becoming red, 6–9 mm. long, convex and reflexed in fruit.
Carpels 5, with styles recurved at the apex or almost completely united; stigmas small.
Drupelets reniform, inserted centrally, (9) 10–11 × 7–8·5 mm.; embryo curved.
Petals bright yellow, 8–11 × 5–6 (9) mm., obovate to oblanceolate.
