Treelet. Twigs terete, c. 6 mm in diam., dark brown, rather densely short-hairy, glabrescent. Leaves 3-5-jugate, the axial parts rather densely fulvous-hairy; petiole terete, at base only slightly swollen, 11-14 cm long; petiolules slightly grooved above, 2-5 mm long. Leaflets oblong to elliptic, 18-26 by 7-13 cm, index 2.5-3, herbaceous, on both sides hairy on midrib and nerves, beneath moreover sparsely so all over the surface; base slightly oblique, rounded to subcordate, sometimes attenuate; apex tapering obtuse-acuminate; midrib prominent above, more strongly so and rounded beneath, nerves 1.5-3 cm apart, angle to midrib 50-55°, straight to slightly curved, the upper ones looped and joined near the margin, slightly sunken above, prominulous beneath, veins and veinlets finely reticulate, veins more or less scalariform, above hardly visible, prominulous beneath. Inflorescences axillary to pseudoterminal, thyrsoid, sometimes with a few short branches, 1.5-5 cm long, dense, with sessile, c. 7-flowered cymes, densely puberulous; bracts deltoid, 1 mm; pedicels 1.5 mm. Flowers white. Sepals ciliate, inside glabrous, outer ovate, 2.5 by 1.8 mm, inner obovate to suborbicular, up to 3 by 2.5 mm, margin slightly petaloid. Petals 4, claw 1 mm, blade elliptic-ovate, 2 by 1.5 mm, outside slightly hairy just above the claw, woolly ciliate below insertion of scale, inside glabrous; scale folded, entire to emar-ginate, long-ciliate, doubled by the crest. Stamens: filaments 1.8 mm, rather thick, sparsely long-hairy in the upper half; anthers ellipsoid, 1 mm, connective rather narrow, glabrous.
