    Habit
    Erect annual or briefly perennial herbs or softly woody shrubs or small trees, often producing a dark gummy juice when the bark is cut.
    Indumentum
    Hairs simple, white or golden.
    Leaves
    Leaves paripinnate, the rachis channelled above; leaflets often in more than 10 pairs, oblong, entire; stipels usually present at all petiolules; stipules truncate at the base, occasionally persistent.
    Flowers
    Flowers in axillary racemes; bracts and bracteoles present but often caducous.
    Calyx
    Calyx campanulate, usually sparsely woolly at the margin; teeth subequal, shorter than the tube.
    Corolla
    Corolla glabrous, blue, mauve, white, red or orange, or more commonly yellow with the standard usually streaked and spotted or continuously veined with purple, the claw with two vertical parallel or divergent variously shaped appendages (these rarely lacking, as in S. grandiflora); blade of wing with transverse lamellate sculpturing (except in >i>S.>i>grandiflora), usually toothed or hooked at the base, the claw much shorter than the blade and shorter than that of the keel; blade of keel rounded below, rounded or broadly pointed at the tip, usually toothed at the base, not, or little, longer than the claw.
    Stamens
    Upper stamen free, sharply bent near the base corresponding to the conspicuous auricles at the base of the filament sheath, the sheath longer than the free parts of the filaments which are curved upwards; anthers all alike, oblong-elliptic (much longer than wide in >i>S.grandiflora), dorsifixed.
    Pistil
    Ovary glabrous or rarely pilose with soft spreading hairs; style glabrous or, less often, pubescent near the tip; stigma small, globose or ovoid.
    Fruits
    Pod usually long, dehiscent, rostrate, usually shortly stipitate, sometimes winged, transversely septate, (2)4–51-seeded.
    Seeds
    Seeds usually ellipsoid or cylindrical, rarely subreniform; hilum circular or, rarely, broadly elliptical, often surrounded by a narrow rim aril.

    Habit
    Erect annual, or briefly perennial, herbs or softly woody shrubs or small trees, often producing a dark gummy juice when the bark is cut
    Indumentum
    Hairs simple, white or golden, never brown or black
    Stipules
    Stipules never spurred or deeply lobed at the base; leaves abruptly pinnate, the rhachis channelled above, usually stipellate, the leaflets usually in more than 10 pairs, oblong, entire
    Flowers
    Flowers in axillary racemes; bracts and bracteoles present but often very caducous
    Calyx
    Calyx bell-shaped, sparsely woolly at the margin; teeth subequal, not arranged in 2 lips, shorter than the tube
    Corolla
    Corolla glabrous, in East African species yellow, the standard nearly always streaked and spotted with purple and having on its claw 2 vertical parallel or divergent variously shaped appendages; blade of wing transversely ribbed, usually toothed or hooked at the base, the claw much shorter than the blade and than that of the keel; keel of a paler yellow than rest of corolla, its blade rounded below, rounded or broadly pointed at the tip, toothed at the base, not, or but little, longer than the claw
    Stamens
    Vexillary stamen wholly free, sharply bent near the base where it may adhere to the appendages of the standard when the flower opens; filament-sheath longer than the free parts of the filaments, which are curved upwards and are not dilated at the tip; anthers all alike, oblong-elliptic, dorsifixed
    Pistil
    Ovary glabrous or rarely pilose with soft spreading hairs; style glabrous or, less often, pubescent near the tip; stigma small, globose or ovoid
    Fruits
    Pod long, dehiscent, rostrate, usually shortly stipitate, transversely septate, 8–50-seeded
    Seeds
    Seeds usually ellipsoid; hilum circular or broadly elliptical near the centre of the longer side of the seed, often surrounded by a narrow rim-aril.
    [LOWO]
    Use
    Used for forage, fibre (from bark), wood, pulp & paper, dye, gum, cover crops, green manure, human food (e.g., flowers of S. grandiflora (L.) Pers.), medicine, ornamentals and fish poisons (useful species include S. grandiflora [agati or corkwood tree] ; S. bispinosa (Jacq.) W.Wight [dhaincha] and S. exaltata (Raf.) Cory [Colorado River hemp] ); some species are invasive weeds and are toxic to livestock (e.g., S. punicea Benth.)
