Usually grows as a small tree seldom exceeding 30 cm dbh but usually flowers and fruits as a shrub.
Base of the compound leaf petiole swollen and clasping the stem or twig. Leaflets near the base of the compound leaf very reduced and scale-like but increasing in size upwards until the maximum size is attained towards the apex of the compound leaf rhachis. Leaflet blades variable, up to 21 x 9 cm. Twigs very pithy.
Cotyledons may be 5-veined. At the tenth leaf stage: terminal leaflets 3-veined, lateral leaflets penninerved; simple leaves 3-veined with long petioles; terminal leaflet of compound leaf with a long stalk, remainder with short stalks.
Distribution and Ecology
Satin Bowerbirds sometimes use this fruit as decoration. Cooper & Cooper (1994).
The colour of the fruits of this species is quite startling. It is more than likely that the colour or its ability to reflect light of other wave lengths is important in attracting dispersal agents (e.g. birds).
Shrub (woody or herbaceous, 1-6 m tall)
