Climbers; young parts pubescent but soon becoming glabrescent. Leaves elliptic or elliptic-lanceolate to ovate, obtuse at base, shortly or abruptly acuminate at apex, 5 - 11 x 1.6 - 5.6 cm, glabrous; petioles 6-14 mm long. Panicles rusty-tomentose, branches usually verticillate. Flowers ca 2 mm across; buds ovoid, ca 2 - 2.5 x 1.5 - 2 mm; pedicels subumbellately crowded or racemed on ultimate branches of panicles, 4 - 5 mm long in buds, ca 14 mm long in fruits, filiform, articulate below middle at about 5 mm from base. Calyx-lobes obovate, oblong to elliptic, ca 1.5 mm long, pubescent or glabrescent. Petals ovate-oblong, oblong-elliptic or ovate, rounded at apex, reflexed, 2 - 6 mm long, white. Filaments ca 1 mm long; anthers ovoid, ca 1 mm long. Ovary pilose. Samara wings ovate-oblong to ovate-lanceolate or elliptic-oblong, broader at base, rounded and narrow at apex, 3.5 - 4.6 x 1.5 - 2 cm, membranous, pale brown; carpophore ca 1 mm long.
