Lianas or climbing shrubs. Stems ca. 5 cm thick; branchlets hairy when young, glabrous when mature. Leaves 3-foliolate; petiole 2.5–7 cm; petiolules glabrous, lateral ones ca. 1 cm; terminal leaflet blade ovate or elliptic, 6–10 × 3–4.5 cm, base subrounded, apex acuminate; lateral leaflet blades ovate, 5–7 × 2–4 cm, base rounded and slightly asymmetric; all leaflet blades leathery, initially minutely tomentose abaxially, later glabrescent, glabrous adaxially, lateral veins 4–6-paired, usually with 1 pair at base (so base appearing 3-veined), all veins slightly prominent abaxially. Panicles axillary, dense, 2–3(–6) cm; rachis and pedicels grayish tomentose. Flowers 4–6 mm in diam., fragrant. Sepals ovate-lanceolate, 1.3–2 mm, softly gray hairy abaxially. Petals white, oblong-oblanceolate, 4–5 mm, glabrous. Stamens ca. 10, glabrous. Carpels 4 or 5; ovary hirsute. Style glabrous. Follicles few, obliquely obovoid, 1–2.5 × 0.5–1.2 cm, densely minutely tomentose, base slightly narrowed, apex obtuse and shortly beaked; pericarp rugulose or warty.

Liana or climbing shrub; stem c. 5 cm thick. Branches 3-4 mm thick, glabrous. Leaves (sub)-glabrous; lateral petiolules c. 0.75 cm. Lateral leaflets usually very oblique, ovate (to oblong-lanceolate), 8-19 by 3.5-10 cm, cuneate to rounded (rarely slightly cordate) at the base, terminal ones obovate (to elliptic), 10-30 by 4½-12 cm, broadly cuneate (rarely rounded to cordate) at the base; all leaflets coriaceous, glabrous or sometimes minutely tomentose on the nerves beneath, shortly (to rather long and slender) blunt-acuminate; nervation prominent beneath; mostly triplinerved, midrib in addition with c. 4 pairs of nerves in the upper half. Panicles dense, 2-3(-6) cm long, minutely greyish pubescent. Flowers (4-)5-merous, heterodistylous, fragrant. Sepals 2 mm long. Petals 5 mm long. Stamens 10, glabrous. Pistils (4-)5. Infructescences small, with few fruits. Fruits slightly oblique, obovoid, 1-2½ by ½-1¼ cm, slightly narrowed at the base, rounded (very rarely shortly beaked) at the apex, rugulose to warty, densely minutely tomentose.
