Description

Fruit: A legume; unilocular; 26–27 cm long; 4–6 cm wide; 0.8–1 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; symmetrical, or asymmetrical; with 1 straight and 1 curved suture; widest near apex ("to scimitar-shaped" with edited comment "no value"); not inflated; flattened; without beak; dorsal suture short long tapered at apex; oblique with longitudinal axis of fruit (slightly); tapered at base; oblique with longitudinal axis of fruit; with the apex and base uniform in texture; ligneous; seed chambers externally invisible; margin not constricted; margin without sulcus; margin plain; wing(s) absent; not stated; tardily with all layers dehiscing; splitting along suture(s). Dehiscence of valves along both sutures; active; with valves separately enrolling. Replum invisible. Epicarp dull; monochrome; brown; with surface texture uniform; glabrous; eglandular; without spines; not smooth; with elevated features; when young veined; reticulately veined; not tuberculate; lenticular (becoming smooth with numerous narrowly elliptic lenticels); not exfoliating; without cracks; without embedded tissue, much thicker than epicarp, running from base to apex. Mesocarp present; surface not veined; 2-layered; without balsamic vesicles; with fibers; without reniform canals; with fibers spongy tissue with transverse over solid layer; ligneous. Endocarp present; visible; dull; opaque; monochrome; brown; without adhering pieces of testa; nonseptate; not exfoliating; remaining fused to mesocarp and epicarp; entire. Seed(s) 3–5; length oblique to fruit length; neither overlapping nor touching; in 1 series. Funiculus 0.1–3 mm long; of 1 length only; thick; straight. Aril absent.

Seed: 31–42 mm long; 21–25 mm wide; 8–10 mm thick; not overgrown; not angular; symmetrical; circular to oblong; compressed; with surface smooth; without visible radicle and cotyledon lobes; without hilar sinus; without umbo on seed faces; without medial ridge on each face. Cuticle not exfoliating; not inflated; not wrinkled. Testa present; without pieces of adhering epicarp; not adhering to endocarp; free from endocarp; glossy; not modified by a bloom; colored; monochrome; reddish to blackish brown; glabrous; smooth, or not smooth; with elevated features; rugose; not stated. Pleurogram absent. Pseudopleurogram absent. Fracture lines absent. Rim absent. Wing(s) absent. Raphe not visible. Hilum present; fully concealed; concealed by funicular remnant; without faboid split; larger than punctiform; not stated; with curved outline; circular; marginal according to radicle tip (?, stated as nearly lateral); recessed; not within corona, halo, or rim. Lens not discernible. Cotyledons smooth; both outer faces convex; both the same thickness; both more or less of equal length; not folded; margin entire 180 degrees from base of radicle; similar at apex; completely concealing radicle; notched at radicle and split over radicle; with the interface division terminating at base of radicle; without margins recessed; inner face flat; glabrous on inner face. Embryonic axis straight; oblique to length of seed; without a joint evident between the radicle and the cotyledons. Radicle differentiated from cotyledon; centered between cotyledons. Plumule rudimentary; glabrous.

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.
