Leaflets opposite to alternate, ovate (to elliptic), often slightly falcate, 2.9-19.2 by 0.8-7.2 cm, index 1.3-5.5, especially basally asymmetrical, acroscopic side broader, coriaceous, not punctate; base attenuate; margin entire, flat (to revolute); apex gradually acuminate to cuspidate (to caudate), usually mucro-nulate; upper surface (glabrous to) sparsely shortly sericeous, (wax); lower surface dull, papillate, (slightly) shortly sericeous, domatia (0 or) 1 small sac to many sacs in axils of (basal) nerves; venation on upper surface (slightly sunken to) flat to raised, below usually raised, concolorous with lamina; nerves 0.3-3.3 cm apart, marginally looped and joined, (less so in lower third of leaflets); veins laxly reticulate, rather indistinct. Inflorescences axillary (to pseudoterminal), (unbranched to) branching basally to especially along the terete, brown sericeous, 1.4-24.2 cm long axis; first order branches up to 9.3 cm long; cymules cin-cinnate, 2-4-flowered; bracts and bracteoles deltate to triangular, outside sericeous, inside (sub)glabrous; bracts 0.6-1.8 mm long; bracteoles 0.2-1.2 mm long; pedicels 1.8-8 mm long, sericeous. Flowers 3.5-4.5 mm in diam.; buds green. Sepals 5, ovate, margin and often outside sericeous, margin with glands, inside (sub)glabrous, green to reddish; 2 outer smaller ones 1-2.8 by 0.8-2.1 mm; 3 inner larger ones 1.4-3.3 by 1.3-3.1 mm, margin petaloid. Petals 5, obovate, 1.9-3.4 by 0.7-1.8 mm, white to yellow; blade obovate, gradually de-current into the 0.3-1.2 mm long claw, margin (and outside) pilose, inside glabrous, apex rounded (to acute); scales 1.1-2 mm long, free, apex not to hardly broadened; crest a pilose flat part of the bifid scale apex. Disc interrupted. Stamens 8; filaments 1.9-5.2 mm long, pilose, especially basally, white; anthers 0.2-0.4 mm long, glabrous, pink. Pistil: ovary 0.3-2 mm long, densely hirsute, yellowish green; style and stigma 0.1-2.5 mm long. Fruit with 1-3 well developed lobes, 1-1.5 by 1-1.9 cm, smooth (to somewhat ribbed), (very) sparsely sericeous, glabrescent, red when fresh, (reddish to) blackish when dry; stipe 1.5-5 mm high, slender; margin blunt; lobes 7-10 by 6.5-10 mm.
