Dehiscence of valves along both sutures; active; with valves enrolling (?). Replum invisible. Epicarp dull; monochrome; brown (greyish); with surface texture uniform; pubescent and indurate (densely); with hairs erect; eglandular; without spines; not smooth; not veined; not tuberculate; not specified except for "velvety"; not exfoliating; without cracks; without embedded tissue, much thicker than epicarp, running from base to apex. Mesocarp present; surface not veined; 3-layered; without balsamic vesicles; without fibers; without reniform canals; with solid layer over spongy layer over solid layer; ligneous. Endocarp present; visible; dull; opaque; monochrome; brown; without adhering pieces of testa; subseptate; not exfoliating; remaining fused to mesocarp and epicarp; entire. Seed(s) 6–8; length parallel with fruit length; neither overlapping nor touching; in 1 series. Funiculus 0.1–2 mm long; of 1 length only; triangular; straight. Aril absent.
Seed: 27–38 mm long; 15–16 mm wide; 8–11 mm thick; not overgrown; not angular; symmetrical; elliptic to oblong; terete to 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; brown; glabrous; not smooth; with elevated features, or recessed features; rugose; pitted with small separate pits; coriaceous. 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; 0.1–10 mm long; with straight outline; apical at apex of radicle tip; flush to recessed; not within corona, halo, or rim. Lens not discernible. Endosperm absent. 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; partially concealing radicle; with lobes; with lobes touching (auriculate); without basal groin formed by lobes; with the interface division terminating at base of radicle; without margins recessed; inner face flat; glabrous on inner face. Embryonic axis slightly S-curved; almost parallel to length of seed (and alteral to the long axis of the seed); without a joint evident between the radicle and the cotyledons. Radicle differentiated from cotyledon; centered between cotyledons. Plumule well developed; glabrous.
