and stamen 0. Ovary subsessile, erect, 2-ovuled; style short, 
hooked. Legume sessile, mostly 2-jointed ; jomts compressed, 
the lower often sterile, the upper 1-seeded, separating.—F1. 
Cap. ii. p. 227. 
Weed-like herbs or undershrubs, frequently viscid-pubescent, common in 
hot countries. Leaves pinnately 3-folioled. Flowers in dense terminal or 
axillary spikes, or solitary or in pairs.—S. setosa, our only species, grows 
at the Aapjes river. 
43. DESMODIUM, DC. 
Calyx 5-parted or deeply 2-lipped, the upper lip 2-fid, lower 
8-fid. Standard roundish; wings oblong, longer than the 
straight, obtuse keel. Stamens “diadelphous. Ovary sessile, 
many-ovuled. Legume several-jointed, the jomts compressed, 
1-seeded, membranous or rigid, separating at maturity. Seeds 
compressed, reniform.—F7. Cap. 1. p. 227. 
Herbs or half-shrubs, common in warm countries. Leaves pinnately 
3-folioled or 1-folioled. Racemes terminal, slender or dense; flowers small, 
purple or white.-—5 South African species, natives of Caffraria and Natal. 
44. ANARTHROSYNE, E. Mey. 
Same as Desmodium, but—Legume compressed, linear-sub- 
falcate, ¢mperfectly jointed, but not spontaneously separating 
into 1-seeded fragments.— Fl. Cap. 11. p. 229. 
Tropical and subtropical plants, with the habit of Desmodium. A. robusta, 
E. M., a tall, robust plant, 3 feet high, softly tomentose, is found near 
Natal. 
45. ALYSICARPUS, Neck. 
Calyx persistent, glumaceous, deeply 4-parted, the upper 
segment emarginate or 2-fid. Corolla papilionaceous, small, 
scarcely longer than the calyx. Stamens diadelphous.  Le- 
gume terete or subcompressed, several-jointed, the joints 
equal-sided, separating.—/. Cap. 11. p. 230. 
Small weed-like plants of hot countries. Leaves 1-folioled, 2-stipuled ; 
stipules and bracts dry. Flowers racemose, pedicelled, in pairs, purple, 
inconspicuous.— 2 South African species (endemic), found in Natal and 
Zululand. 
46. REQUIENTA, DC. 
Calyx bell-shaped, 5-fid, the segments acute, the lowest 
longest. Standard obovate ; keel obtuse, 2- petalous. Stamens 
monadelphous, the tube cleft above. Ovary sessile, 1-ovuled ; 
style short, curved. Legume oval, compressed, mucronate, 
L-seeded.—Fl. Cap. il. p. 230. 
Tomentose-canescent half-shrubs of doubtful affinity. Leaves alternate, 
1-folioled ; leaflets obcordate, closely penninerved, mucronate. Stipules 
free. Flowers very small, subsessile, solitary or clustered.—&. sphero- 
sperma, DC., our only species, is found in Transvaal.
