They grow naturally in New Guinea, New Britain, New Ireland, Bougainville, the Andaman and Nicobar Islands, Sumatra and Cape York Peninsula, Queensland, Australia.[2][6][7][8]
- Trees or sometimes remaining as shrubs, with greyish brown bark; monoecious; indumentum only simple hairs.
- Branchlets smooth or slightly grooved, lenticellate, hairy in new growth.
- Leaves paripinnate, without stipules, arranged alternately, petiole attachment to branch swollen, that and rachis not winged.
- Leaflets arranged ± opposite, increasing in size from base to apex, first ovate then to elliptic and obovate; petiolule short with a pulvinule; blade base cuneate, margins smooth, flat, both surfaces smooth apart from undersides’ hair–tufts domatia and raised veins.
- Inflorescences ramiflorous or arising from leaf axils, reduced thyrses with each node bearing usually 3 short cymes.
- Flowers regular–symmetrical, yellow–cream–white, pedicellate. Calyx of 5 sepals with triangular to oval–shaped lobes. Petals tiny, with their scales larger and usually without crests. Disc circular surrounding the bases of the 8–10 hairy stamens. Ovary 2 locular.
