Treelet, up to 10 m high, dbh up to 20 cm, but often much smaller; bark rather smooth, light grey, often patchy. Twigs terete, 3-5 mm thick, fairly densely short fulvous-hairy; branchlets glabrous. Leaves 1-3-(or 4-)jugate; petiole terete, 0.75-4 cm long; petiolules 0-5 mm long, terete. Leaflets: basal pair often strongly falcate, upper pairs elliptic to obovate, 1.5-15 by 1-10 cm, basal pair stipule-like and much smaller than the others, middle and upper pair either of about the same size or the upper one distinctly bigger, index 1.25-2, fairly thin (to stiff pergamentaceous or ± bullate); midrib and nerves on both sides densely hairy, in be-tween very sparsely above, beneath rather sparse-ly hairy; base symmetrical to variably oblique, in the basal pair the acroscopic side more strongly developed to in extreme cases the basiscopic side not developed at all, in the upper pair the basiscopic side stronger developed, the base rounded to slight-ly cordate (to obtuse to acute); margin dentate; apex rounded (or obtuse), mucronulate; midrib promi-nent and rounded on both sides; nerves 0.75-1.5 cm apart, ± obliquely patent, slightly curved to nearly straight, ending in marginal teeth, above slightly, beneath a bit more prominent; veins and veinlets above rather densely reticulate, beneath laxer. Inflorescences axillary, widely branched panicles, 3-10 cm long; branches up to 7 cm long, spreading, racemoid, densely hairy. Sepals 4, c. 1.5 mm high, somewhat less than half connate, inside sparsely hairy mainly on the lobes. Petals absent. Stamens 6 or 7; filaments c. 2.5 mm long; anthers 1-1.25 mm long. Pistil 2-locular, stigma slightly 2-lobed. Fruits 2-lobed, the lobes globular, 5-7 mm diam., above with a triangular to falcate, up to 7 mm long wing, densely shortly fulvous hairy.
