Description

Fruit: A legume; 12.5–17.5 cm long; 4.5–5 cm wide; 0.1–0.3 cm thick; 2–9 times longer than wide; with deciduous androecial sheath; with deciduous corolla; with deciduous calyx; without orifice formed by curving of fruit or fruit segments; straight; not plicate; not twisted; asymmetrical; dolabriform; with 1 straight and 1 curved suture; widest near apex; not inflated; compressed; with beak; straight; with solid beak the same color and texture as fruit; tapered at apex; oblique with longitudinal axis of fruit; rounded at base; oblique with longitudinal axis of fruit; with the apex and base uniform in texture; leathery; seed chambers externally invisible; margin not constricted; margin without sulcus; margin plain; wing(s) absent; stipitate; with the stipe 8–10 mm long. Replum invisible. Epicarp dull; monochrome; brown; with surface texture uniform; glabrous; glandular; with glandular dots (ca. 0.2 mm in diam, dark red); distributed over entire fruit; without spines; not smooth; with elevated features; veined; transversely veined relative to fruit length and reticulately veined; not tuberculate; not exfoliating; without cracks; without embedded tissue, much thicker than epicarp, running from base to apex (assumed).

Tribal Notes

Tribe Detarieae

Bruneau et al. (2000) carried out extensive phylogenetic analyses of tribes Amherstieae and Detarieae. They concluded that they form a single monophyletic group. Therefore, they supported Polhill's (1995a, 1995b) decision to unite the two tribes.
