Detailed description

Tree up to 8m high, usually with an erect trunk and spreading branches; young shoots pilose, sometimes densely so, but soon becoming glabrate. Buds large; outer scales glabrous, purplish, inner scales densely covered with white hairs towards apex. Leaves imparpinnate with up to 8 pairs of leaflets; petiole 20~35mm long, green or brown to purplish, pilose, but hairs deciduous, sometimes with stalked glands; leaflets narrowly oblong or oblong-elliptic, sometimes lanceolate-elliptic, 30~50 x 8~20mm, obtuse to acute, mostly sessile, deep green and glabrous or finely hairy above, paler and finely to densely pilose below, serrate along whole length or sometimes in upper 2/3 only; leaflets of juvenile plants and suckering shoots narrowly elliptic to elliptic-ovate, deeply and jaggedly toothed; stipules generally deciduous, small, acuminate. Infl. drooping, up to approx. 120 mm across; pedicels and branchlets white-villous, becoming glabrate by fruiting. Sepal lobes broadly triangular, 0.6~1.3mm diam., generally orbicular with abbreviated claw, white. Fruit depressed-globose, sometimes oblong-obovoid, 5~10mm diam., deep orange to scarlet, sometimes crimson, glossy. (Webb et. al., 1988)
