Leguminosae, R.K. Brummitt, D.K. Harder, G.P. Lewis, J.M. Lock, R.M. Polhill & B. Verdcourt. Flora Zambesiaca 3:3. 2007

Morphology General 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.
Morphology General Indumentum
Hairs simple, white or golden.
Morphology 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.
Morphology Reproductive morphology Flowers
Flowers in axillary racemes; bracts and bracteoles present but often caducous.
Morphology Reproductive morphology Flowers Calyx
Calyx campanulate, usually sparsely woolly at the margin; teeth subequal, shorter than the tube.
Morphology Reproductive morphology Flowers 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.
Morphology Reproductive morphology Flowers Androecium 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.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary glabrous or rarely pilose with soft spreading hairs; style glabrous or, less often, pubescent near the tip; stigma small, globose or ovoid.
Morphology Reproductive morphology Fruits
Pod usually long, dehiscent, rostrate, usually shortly stipitate, sometimes winged, transversely septate, (2)4–51-seeded.
Morphology Reproductive morphology Seeds
Seeds usually ellipsoid or cylindrical, rarely subreniform; hilum circular or, rarely, broadly elliptical, often surrounded by a narrow rim aril.

Morphology General 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
Morphology General Indumentum
Hairs simple, white or golden, never brown or black
Morphology Leaves 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
Morphology Reproductive morphology Flowers

Morphology Reproductive morphology Flowers Calyx
Calyx bell-shaped, sparsely woolly at the margin; teeth subequal, not arranged in 2 lips, shorter than the tube
Morphology Reproductive morphology Flowers 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
Morphology Reproductive morphology Flowers Androecium 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
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary glabrous or rarely pilose with soft spreading hairs; style glabrous or, less often, pubescent near the tip; stigma small, globose or ovoid

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.)
