Ovary tomentose; style c. 3·5 mm. long, pubescent, shortly 3-lobed.
Fruit c. 1·5 × 1 cm., subellipsoid, densely and shortly whitish-tomentose.
Sepals c. 3 mm. long, oblong, tomentose.
Inflorescence cymose, short, axillary; peduncle 1–3 mm. long, free; pedicels c. 1 mm. long, articulated at the base of calyx; bracts small, caducous.
Leaves 5–12 × 2–5 cm., oblong-elliptic or oblong, papyraceous, glabrous on both surfaces, subacute or obtuse at the apex, subrounded or obtuse at the base; lateral nerves 5–6 pairs, slightly conspicuous above, prominent below; petiole c. 5 mm. long, pubescent or glabrescent; stipules c. 2 mm. long, subulate, caducous.
Scandent shrub; branches and branchlets terete, pubescent; bark longitudinally striate, covered with small and numerous lenticels.
Petals c. 4 mm. long, lanceolate, pubescent, glabrous at the apex, 2-lobed.
Inflorescences 3–5 times branched, tomentose; peduncle 2–5 mm. long; bracts and bracteoles minute, triangular, ± 0.5–1.5 mm. long; pedicel 1–2.5 mm. long, the upper part 0–0.5 mm. long.
Sepals erect or slightly spreading, occasionally some sepals reflexed, oblong, (3–)3.5–4.5(–5) × 1–2 mm., obtuse, rounded or acutish, both sides tomentose, more densely so outside.
Stipules usually early caducous, narrowly triangular-subulate, (1–)2–3 mm. long, shortly appressed pubescent.
Petiole (2–)4–7(–11) mm. long, shortly appressed pubescent, glabrescent; blade coriaceous, elliptic, oblong-elliptic, ovate-elliptic, or ovate, rounded to obtuse or truncate-cordate and subequal at base, gradually tapering into an obtuse or truncate or sometimes acute tip, (5–)8–15(–18) × (2–)3–6(–9) cm., glabrous or on one or both surfaces sparsely shortly appressed pubescent on midrib and on the (6–)7–9(–12) pairs of main lateral nerves, soon glabrescent, when young sometimes sparsely pubescent on the entire upper surface, margins usually not or only slightly revolute.
Liana, lianescent shrub or shrub.
Stamens as long as or slightly shorter than the petals, erect; filaments hairy like the petals but usually less densely so to subglabrous.
Branches glabrous or nearly so, usually with rather small dispersed lenticels; branchlets shortly appressed pubescent, often densely so when young, glabrescent, usually lenticellate when older.
Petals narrowly obovate-oblong in outline, (4–)4.5–5.5(–6) mm. long, split 1–1.5 mm., inside loosely long-pilose below split, outside more appressed pilose below split.
Pistil 4.5–5.5(–6.5) mm. long, lanate; ovary 3-locular.
Fruits obovoid-ellipsoid or subglobose, usually lobed when more than 1-seeded, slightly laterally compressed, 13–20 mm. long, 9–14(–20) mm. in diameter, 1–2(–3)-seeded, densely tomentellous, in dried fruits slightly wrinkled and often obscurely muricate; endocarp inside with up to ± 3 mm. long, golden-brown, acicular minutely barbed hairs.
