A small tree seldom exceeding 20 cm dbh. Inner blaze finely layered. Blaze odour noticeable but difficult to describe.

Leaves

Terminal buds and young shoots clothed in pale, almost prostrate hairs. Leaflet blades about 5-11 x 2-6 cm. Hairs visible on the upper surface of the leaf blade with the aid of a lens. Domatia, if present, are tufts of hairs.

Flowers

Inflorescences longer than the leaves. Pedicels about 7-8 mm long. Calyx pubescent on the outer surface, tube about 1.5 mm long, lobes narrow, about 1 mm long. Petals glabrous, about 22-27 mm long. Staminal tube about 20-25 mm long, lobed or fringed at the apex, anthers +/- sessile, rostrate. Disk +/- cupular, small and inconspicuous. Ovary about 1 mm long. Style about 16 mm long, stigma about 2.5 mm long.

Fruit

Fruits +/- discoid or depressed globular, about 8-10 x 12-16 mm before opening, inner surface bright yellow, calyx persistent at the base. Seeds about 5 x 3.5 mm, aril +/- lateral not enclosing the seed. Embryo about 4-5 mm long, cotyledons many times wider than the radicle.

Seedlings

Cotyledons obovate, 13-20 mm long with a few hairs towards the base. First few leaves usually toothed or lobed. At the tenth leaf stage: leaf blade obovate or elliptic, apex acute, base cuneate or attenuate, hairy on the upper surface, underside sometimes with domatia (tufts of hairs); petiole hairy.

Natural History

This deciduous shrub to small tree has great horticultural potential for tropical gardens. Masses of cream flowers are produced just before the new leaves.
