Morphology General Habit
Liane to 6 m.; older stems brown, glabrous, striate and slightly rugulose; young stems dark brown, puberulous, striate and lenticellate, hairy at the nodes.
Morphology Leaves
Leaves 3-foliolate; petiole 3–11 cm. long, with a line of hairs above; petiolules slightly channelled, 0.7–2.5 cm. long; leaflets elliptic to ovate, 4.5–9.5 cm. long, 2.5–6 cm. wide, shortly to distinctly acuminate at the apex, rounded, subcordate or almost cuneate at the base, rather thick, shortly rather roughly pubescent above, chiefly on the midrib, sparsely pilose on the nerves beneath or more densely so on both surfaces, even ± velvety beneath; lateral nerves 3–5 on each side.
Morphology Reproductive morphology Inflorescences
Inflorescences probably 15–20-flowered; buds ellipsoid, 3–6.5 mm. long.
Morphology Reproductive morphology Flowers
Flowers greenish white.
Morphology Reproductive morphology Flowers Tepal
Outer tepals 5–11 mm. long, 5-nerved, pubescent outside; inner slightly shorter, 1-nerved, almost glabrous.
Morphology Reproductive morphology Flowers Androecium Stamens Filaments
Filament-appendages urceolate, up to 3 mm. long, shortly stipitate, the margins laciniate; inter-staminal glands minute; connectives papillose.
Morphology Reproductive morphology Flowers Gynoecium Stigma
Stigma 3–5-lobed.
Morphology Reproductive morphology Fruits
Fruit-body 0.8–1.3 cm. long, 7–8 mm. wide, (2–)3–4-winged; wings broadly rounded, the larger pair 3.5–4 cm. long, 3 cm. wide, the smaller 1.3–2.5 cm. long, 0.5–1.2 cm. wide.
Morphology Reproductive morphology Seeds
Seed depressed ovoid, 6.5 mm. long, 5.5 mm. wide, the margin keeled and faces yellow glandular.
