Entada camerunensis Villiers, Bull. Mus. Natl. Hist. Nat., B, Adansonia 4: 193. 1983.

Type.

CAMEROON. West Kongolo , on bank of River Bayo, R. Letouzey 3534 (holotype: P [P00418283, P00418284 & P00418285]; isotype: YA [YA0023378]) .

Description.

Liana, sometimes sarmentose, stem twisted, to 15 cm diameter at base. Leaves: a conspicuous ridge at petiole base; rachis 5.5-7.9(-9.5) cm, grooved above, tendrils absent, but petioles sometimes modified for climbing; pinnae 2-4 pairs per leaf, 3.5-10(-16) cm long with 5-10 pairs of leaflets; leaflets 1-2.5 × 0.3-1.1 cm, obovate-oblong, increasing in size distally, apex truncate to retuse, base asymmetric with proximal margin rounded, distal margin attenuate, lamina pubescent. Inflorescence: a terminal or axillary spiciform raceme, 7-9.5 cm long, solitary or 2 per axil, peduncle and rachis pubescent. Flowers: yellow to greenish-yellow, staminate or bisexual, pedicels 0.5-0.75 mm long; calyx cupular, 0.75-1.25 mm long, shallowly toothed, glabrous to sparsely pubescent at tooth apices; petals 3-3.25 × 0.6-0.8 mm, elliptic to obovate; stamen filaments 3-5 mm long. Fruit: a torulose, laterally compressed, slightly curved craspedium, 20-29 × 7-9 cm, with transverse septa between seeds dividing the fruit into one-seeded segments which, upon ripening, fall from the persistent replum; segments distinctly umbonate over seeds. Seeds: elliptic-oblong, laterally compressed, 1.7-1.9 × 0.9-1 cm, pleurogram open.
