Medium-sized to big tree, up to c. 42 m. Leaves 2-6(-7)-jugate; leaflets elliptic to oblong, basal ones sometimes a bit ovate, upper ones sometimes ± obovate, usually rather large, up to 25(-38) by 10(—18) cm, base rounded to truncate, sometimes acute, entire, firmly coriaceous, pubescent, rarely subglabrous, rarely with domatia. Panicles erect, spreading, lax to rather dense; lower primary side-axes usually subtended by small leaves. Sepals usually densely pubescent, rarely on the outside sparsely so to subglabrous. Outer petals pubescent outside, rarely glabrous. Inner petals with fimbriate or ciliolate tips. Ovary partly or entirely but almost always distinctly and densely pubescent, very rarely nearly glabrous. Endocarps subglobose, often somewhat depressed and oblique, 3.5—5.5(—8) mm diam., with rather vague to distinct, ± prominent reticulum, with usually very prominent, rather sharp median keel which does not run out into a ventral processus or tubercle; ventral pore not or not much sunken.
