特徵描述

生活型

twiner

形態特徵

Stems twining, brownish-tomentose.
Leaves chartaceous, 6–11 cm long, 5–9 cm wide, apex acute, base cordate or subtruncate,upper surface glabrous, lower surface silky-tomentose, lateral veins 7–10 on each side of midrib; petiole 1.5–6 cm long, brownish tomentose.
Inflorescences racemes, 4–6- flowered; peduncle 1.5–2 cm long; pedicel 8 mm long, silky pubescent; bracts oblong, 6 mm long, 4 mm wide; sepals ovate-oblong, 5–8 mm long, 3–4 mm wide, tomentose outside; corolla deeply 5-lobed, tube 5 mm long, lobes linear, 15 mm long, reflexed, apex obtuse, pubescent outside; stamens 5, alternate with lobes, filaments 10 mm long; style filiform, 15 mm long.
Fruits globose, pericarp thin-coriaceous, red; seeds black, glabrous.
The application of the name A. obtusifolia Loureiro is uncertain, because no type specimen for it has been located. Whether the Taiwan plants are conspecific with those called A. obtusifolia in southern China, Hainan Island, and Vietnam is impossible to say without a more thorough study. We therefore retain A. formosana for the Taiwan plants until further nomenclatural research clarifies the situation.
