Inflorescence clothed in rusty hairs. Young inflorescence bracts 3-10 x 1-8 mm. Flowers 6-8 mm diam. Calyx shortly cupular, lobes 5, ovate, subequal, flat, not concave, each lobe about 4 mm long, densely clothed in dark reddish brown hairs. Petals obovate, about 5 mm long, each petal with 2 gland-like structures towards the base on the inner (adaxial) surface. Fifth petal slightly reduced. Stamens eight.


Seeds flat, about 15-20 mm wide, completely enveloped by the aril. Fruits hairy externally.

At the tenth leaf stage: simple leaf or leaflet of compound leaf broadly elliptic or obovate, apex rounded, margin recurved, hairy on the upper surface and along midrib and main lateral veins; leaflets with lateral veins very prominent on the lower surface, depressed on the upper surface, forming loops just inside the margins; terminal bud, stem and petiole densely clothed in long, brown hairs.

Distribution and Ecology

Endemic to NEQ, restricted to the area between Cooktown and Innisfail. Altitudinal range from sea level to 600 m. Grows in well developed lowland and upland rain forest.

Natural History & Notes

The very large compound leaves and massive panicles of flowers make this a desirable small tree for tropical gardens.
