Descriptions

Leguminosae, J.P.M. Brenan. Flora Zambesiaca 3:1. 1970

Note
A very variable and taxonomically complex species, widespread in Africa and Asia, reaching Australia.
Morphology General Habit
Shrub or small tree 1-8(12) m. high, sometimes suckering and thicket-forming or (fide Greenway) even scandent, with rough bark and armed with spines terminating short lateral spreading twigs which often bear leaves and flowers; young branchlets usually ± pubescent, sometimes puberulous or even glabrous.
Morphology Leaves
Leaves with (2)5-19(21 fide F.C.B.) pairs of pinnae; rhachis (with petiole) 0·5-20 cm. long, with one stalked or occasionally sessile gland between each pair, or at least the distal and basal pairs, of pinnae; leaflets 9-41 pairs, 1-11(14) x 0·3-4(5·5) mm., linear to oblong.
Morphology Reproductive morphology Inflorescences
Inflorescences yellow in apical hermaphrodite part, mauve or pink or sometimes white in lower neuter part, 2-5 cm. long, pendent on solitary or apparently fascicled peduncles 1-9 cm. long.
Morphology Reproductive morphology Flowers Calyx
Calyx 0·6-1·25 mm. long.
Morphology Reproductive morphology Flowers Corolla
Corolla 1·5-3 mm. long.
Morphology Reproductive morphology Flowers Androecium
Stamen-filaments of hermaphrodite flowers 3·25-3·5 mm. long; staminodes 4-17 mm. long.
Morphology Reproductive morphology Fruits
Pods 2-10 x 0·5-2·6 cm.
Morphology Reproductive morphology Seeds
Seeds 4-6 x 3-4·5 mm., deep-brown, glossy.

Morphology Reproductive morphology Fruits
Pods clustered, 2–10 x 0.4–1.4(–2) cm, contorted, indehiscent.
Distribution
N1; C2; S1–3 widespread in tropical Africa, also in Arabia, tropical Asia and Australia.
Ecology
Altitude range 30–1300 m.
Vernacular

Note
This variable species was subdivided into numerous subspecies and varieties by Brenan & Brummitt in Bol. Soc. Brot., ser. 2, 39: 77–115 (1965). One of these, subsp. argillicola with only 4–7 pairs of pinnae and not strongly coiled pods, was described with the type from Somalia. Today a much wider variation is known in Somalia and the application of the infraspecific names available is very difficult. The species is therefore here not formally subdivided.
