Midrib raised on the upper surface of the leaflet blade. Leaflet blades about 8-17 x 3.5-5.5 cm. Compound leaf petiole rather sharply angular from the base to the point of attachment of the first pair of leaflets. Domatia (if present) are tufts of hairs around a glandular depression. Terminal buds shaped like a lance head.
Calyx cup-shaped, lobes very small and inconspicuous. Outer surface of the corolla clothed in pale, +/- prostrate hairs. Petals about 7 mm long. Stamens eight. Disk surrounds the ovary and resembles a staminal tube. Ovary pubescent.
Fruits +/- globular, often 4-lobed in transverse section, about 20-30 mm long, outer surface glabrous, or sparsely tomentellous. Sarcotesta orange or yellow except for a brown or black patch. Cotyledons cream but brown on the periphery.
First pair of leaves compound with two leaflets. At the tenth leaf stage: leaflet blades elliptic, apex acuminate, glabrous on the upper surface; petiole and rhachis of compound leaf clothed in short, erect hairs.
Distribution and Ecology
Occurs in NT, CYP and NEQ. Altitudinal range from sea level to 1100 m. Grows in well developed rain forest on a variety of sites but tends to be more abundant in drier, more seasonal rain forest. Also occurs in Malesia and the Solomon Islands.
Produces a useful general purpose timber.
