≡ Entada pervillei var. genuina R. Vig., Notul. Syst. (Paris) 13: 347. 1949. Nom. superfl.

Type.

MADAGASCAR. Nossi Bé [Nosy Bé], J.M. Hildebrandt 2952 (holotype: B?; isotypes: JE [JE00003317, JE00003318], K, M [M0218736], P) .

Basionym.

Piptadenia? pervillei Vatke, Linnea 43: 109. 1881.

Description.

Tree to 15 m tall, with elevated nectaries at nodes. Leaves: rachis 8-18 cm long, ridged above, sometimes with elevated nectaries between distal pairs of pinnae, tendrils lacking; pinnae 7-16 pairs per leaf, 3.5-11 cm long, with 26-72 pairs of leaflets; leaflets (4-)6-10.5 × 1-1.5 mm, linear-oblong, sub-falcate, apex acute to rounded or obtuse, base asymmetric, rounded on the proximal margin, attenuate on the distal margin, lamina glabrous, margins ciliolate to ciliate at base. Inflorescence: a terminal panicle of spikes, each spike 7-25 cm long, spike rachis slightly pubescent. Flowers: white, sub-sessile; calyx obconical, 1-1.6 mm long, shallowly toothed, glabrous; petals 2.5-4 × 1 mm; stamen filaments 5-6.5 mm long. Fruit: a torulose, laterally compressed craspedium, 18-25 × 2.5-4.5 cm, with transverse septa between seeds dividing the fruit into one-seeded segments which, upon ripening, fall from the persistent replum. Seeds: oblong-ovate, 1.7 × 1 cm, brown, pleurogram indistinct.

Distribution.

Madagascar (north, northeast and west).

Habitat and ecology.

Humid evergreen forest and seasonally dry deciduous woodland up to 700 m alt.; sandy or calcareous soils.

Note.

The “?” in the basionym Piptadenia? pervillei Vatke is associated with the genus Piptadenia and not with the species name Piptadenia pervillei because Vatke was not certain about the generic position of the species. Entada pervillei var. genuina R. Vig. (i.e. equivalent to the typical variety var. Entada pervillei pervillei ) is a superfluous name because, once var. Entada pervillei louvellii was moved to E. louvellii , the typical variety was effectively disbanded.
