Craibia Harms & Dunn

Genus

Angiosperms > Fabales > Fabaceae

Characteristics

Slow-growing trees or shrubs. Hairs nearly always golden-brown or black. Leaves pulvinate, usually imparipinnate, with up to 11 alternate (or rarely opposite) leaflets, rarely, outside the Flora area, 1-foliolate; buds well developed, flattened, oval or round, with broad scales; stipellae present or absent; petiolules wrinkled; leaflets leathery, acuminate, glabrous or glabrescent above and often beneath, with a strongly developed nerve-network, the principal nerves breaking up before reaching the margin. Inflorescence a terminal or, less often, axillary raceme or a terminal panicle; bracts and bracteoles caducous. Flowers usually fragrant. Calyx-lobes broad, much shorter than the tube, the upper pair united for at least half their length. Corolla white or minutely speckled and streaked with pink or purple, glabrous except, rarely, for a few weak hairs at the edge of the standard; claw of standard short, clearly distinct from the usually oblong lamina which is without folds or processes at the base; wings and keel with well-marked auricles. Vexillary stamen essentially free, curving away from the others at the base and tip but sometimes slightly adhering in the middle; anthers all alike, without appendages. Disc absent. Ovary shortly stipitate, glabrous or ± tomentose with long golden-brown hairs; ovules 2–6 in the distal part of the ovary; style cylindrical; stigma small, terminal, punctate or capitate. Pod shortly stipitate, flat, tapering at the base, markedly asymmetric, the lower suture evenly convex, the upper ± concave below, convex distally, glabrous or glabrescent, shortly beaked, dehiscing into thin, stiff, woody, twisted valves. Seeds 1–3, ellipsoid, black or dark brown; hilum short, near one end of the seed, surrounded by a short white cupular aril which is produced at one side into a curved strap-like process clasping the funicle; cotyledons hypogeal.

Pod shortly stipitate, flat, tapering at the base, asymmetric, the lower margin evenly curved but the upper ± sinuous, ± concave towards the base and convex in upper half, glabrous or glabrescent, shortly beaked, dehiscing into thin but stiffly woody twisted valves, 1–4-seeded.
Leaves usually imparipinnate, the leaflets ± leathery, entire, nearly always alternate (1-foliolate in one West African species); stipels present or absent; pulvinus present; buds well developed, flattened, oval or round with broad scales.
Seeds black or dark brown, ellipsoid; hilum short, near one end of seed, surrounded by a short white cupular rim aril which is produced on one side into a curved strap-shaped process clasping the funicle.
Corolla white or speckled and streaked with pink or purple, glabrous or with few hairs; standard without folds or processes, with short distinct claw; wings and keel petals with well marked auricles.
Flowers usually fragrant, in axillary or terminal racemes or terminal panicles, the pedicels inserted singly; bracts and bracteoles deciduous.
Upper stamen almost free, curving away from the sheath at the base and apex but sometimes lightly adhering in the middle; anthers uniform.
Ovary glabrous or pubescent, shortly stipitate, 2–6-ovuled; style cylindrical; stigma small, terminal, punctate or capitate.
Calyx with broad lobes much shorter than the tube, the upper pair united for at least half their length.
Evergreen trees or shrubs.
Disk absent.
