Leaves (2-)3-7(-l 1)-jugate; petiole 1.5-7.5 cm long; rachis 4-18 cm long, terete to marginate. Leaflets narrowly ovate (or elliptic), (2.5-)3.5-10.5(-18) by (l-)2-4(-5) cm, index (1.7-)2-4(-5), (slightly) oblique, per-gamentaceous, sometimes coriaceous, above glabrous or rarely very sparsely hairy, except for the sparsely to densely short-hairy (or densely long-hairy) midrib, nerves, nerve axils, and margin at the base sometimes sparsely hairy, beneath short-or long-hairy, (very) sparsely (to densely) so on the midrib, nerve axils and margin at the base (very) sparsely so; apex acute or short to long acuminate, the very apex obtuse (or slightly retuse); nerves 5-16(-22) mm apart; domatia mostly absent. Inflorescences sometimes simple, mostly branched; bracts and bracteoles up to 3 mm long; pedicels up to 2 mm long. Flowers greenish, whitish or yellowish (brown), c. 5 mm in diam. Sepals 1.5-2.5 by 1-2 mm, outside glabrous or sparsely to sometimes densely hairy, inside subglabrous. Disc (1.2-) 1.5-1.8 mm in diam. Stamens: filaments with long patent hairs, in male flowers (2.5-)3.2-3.5 mm long, in female flowers (0.5-) 1.5-2 mm long; anthers narrowly cordate to ovate, 0.6-0.8 by 0.4-0.7 mm, glabrous or sometimes sparsely hairy. Ovary ellipsoid, 2-celled, (1.5-)1.8-2 by (1-)1.3-1.5 mm, sparsely hairy, often densely hairy along the sutures, mostly densely scaly; style 1—1.2(—1.5) mm long; pistillode 0.5-1.2 mm long. Fruits obovoid to globular, rarely transversely ellipsoid, outside mostly (very) sparsely hairy, often more densely so along the sutures, rarely densely hairy all over, mostly ± densely scaly, inside densely hairy.
