Trees 3.5-25 m high, dbh 10-35 cm, bole flanged all the way up; Leaves (3-)4-6(-8)-jugate; Inflorescences axillary, 5-20(-34.5) cm long, with long or short, patent branches, tomentose, glabrescent, laxly flowered; Sepals white to brown, persisting, outside appressed-hairy except rim, margin ciliate and with glands, inside appressed-hairy, outer elliptic to triangular, 1-2.9 by 0.8-2.2 mm, scarious rim narrow, inner elliptic to orbicular, 1.6-3.5 by 0.8-2.9 mm, scarious rim wide, irregularly dentate at apex. Petals cream to pink, elliptic to obovate, 0.8-2.9 by 0.5-2.2 mm, glabrous or appressed-hairy in basal part on both sides, margin ciliate, sometimes (Schlechter 14436) with an apical tuft of hairs; Stamens 8, exserted; Ovary 3-celled; Fruits yellow to reddish brown, globular, 9-15 by 10-15 mm; Seeds 9-10 by 6-8 mm, basal-ly attached, testa shiny black;


Asia-Tropical: Maluku (Maluku present), Papua New Guinea present
Malesia: Moluccas, Papua New Guinea.


1. Plants from lower altitudes are more appressed-hairy and have wider leaflets than those from higher altitudes.
Schlechter 14436, 19201 have elliptic leaflets and small flowers. Conn & Kairo 454 has (in part) entire leaflets, large flower buds and flowers. The septum of the fruits of Hoogland & Craven 10129 is sparsely hairy. In Brass 7769 the inside of the fruit wall is thinly appressed-hairy, the septa are almost glabrous.
Brass 32366 with (in part) entire leaflets, petals with a claw of 0.4-0.6 mm, and a reticulate instead of a rugulate ornamentation of the pollen grains, probably belongs to the present species. As does UPNG 8098 which is larger in most parts than all other specimens.
