Merrill, E.D. & Perry, L.M. (1940) Journal of the Arnold Arboretum 21: 525. Type: British New Guinea: Western Division, Wassi Kussa River, Tarara, Brass 8379 (Type).
Capsule 2-winged, rarely 3-winged, capsule + wings about 16-28 x 15-30 mm, glabrous, wings about (4)6-9 mm wide.
Cotyledons linear, about 20-27 x 4-5 mm. First pair of leaves alternate or subopposite, margins lobed. Subsequent leaves alternate, margins entire. At the tenth leaf stage: leaf blade elliptic, apex retuse. Young leaves covered with a clear varnish and midrib raised on the upper surface. Seed germination time 7 to 52 days.
Occurs in CYP and NEQ. Altitudinal range from sea level to 500 m. Grows in open forest but also found on the margins of rain forest, monsoon forest and beach forest. This species is favoured by disturbance, particularly severe fires, and regenerates en masse producing a thicket which is difficult to walk through because of the density and toughness of individual stems. Also occurs in New Guinea.
A widespread small tree that should be tried in tropical gardens. Fruits are winged and ripen to brown.
