minal, 3-2} in. long, on longer downy peduncles, the flowers in 2~5 
often distinctly separated fascicles. Bracts linear-lanceolate, +’in., and 
linear bracteoles persistent. Calyx } in., grey-canescent ; teeth short, 
deltoid. Corolla purple, $ in. Pod 21—24 lines long, nearly } in. 
broad, finely pubescent, straight, 8—9-seeded. 
Lower Guinea. Pungo Andongo, Dr. Welwitsch! 
A plant gathered by Dr. Welwitsch in Cazengo at 2000 ft. above sea-level is pro- 
bably a new closely-allied species, but the specimens are not complete enough to de- 
scribe fully. It is as downy as this, but the leaflets are rather fewer, the racemes all 
axillary, and pods much shorter (15-18 lines). 
51. CENTROSEMA, DC.; Benth. et Hook. f. Gen. Plant. i. 527. 
Calyx shortly campanulate, the teeth subequal or the two upper ones 
connate. Standard orbicular; wings falcate-obovate; keel broad, 
incurved. Upper stamen free or more or less connate with the others; 
anthers uniform. Ovary subsessile, multiovulate ; style incurved, more 
or less dilated at the apex, slightly bearded round a terminal stigma. 
Pod subsessile, linear, subcompressed, two-valved, subseptate between 
the seeds internally, the sutures incrassated, the valves on both sides 
traversed by a prominent nerve near the edge or winged near the lower 
suture.—Climbing herbs or undershrubs. 
‘ A dit genus, confined to America, except for the occurrence of this species in our 
ounds. 
1. C. virginiana, Benth. in Ann. Mus. Vind. ii. 120. Stems slender, 
firm-herbaceous, wide-climbing, glabrous or slightly pubescent. Petioles 
lin. long; leaflets three, ovate, 14-2 in. long, 2-1 in. broad, promi- 
nently veined, firm, glabrous or slightly hairy. Peduncles axillary, 
1—4-tlowered, exceeding the petioles. Pedicels 4 in. long, with a pair 
of ovate acuminate striated bracteoles at the apex, which nearly equal 
the calyx, which is 3-} in. deep, the upper teeth linear, reaching half- 
way down, the lowest longer. Corolla an inch deep, violet-purple, the 
standard an inch broad. Pod 3-4 in. long, 14-2 lines broad, glabrous, 
nearly straight, 12—18-seeded.— C. decumbens, Mart., Benth. I. ¢. Clitoria 
virginiana, Linn. Sp. Pl. 753. DC. Prod. ii. 234. 
Upper Guinea. Cape Coast, Vogel! 
A common Tropical American species, extending north to Maryland. 
52. CLITORIA, Linn.; Benth. et Hook. f. Gen. Plant. i. 528. 
Calyx tubular with deep teeth and two large persistent bracteoles. 
Corolla large, the ample standard much exceeding the wings an¢ 
incurved acute keel. Stamens diadelphous; anthers uniform. Ovary 
stipitate, linear, multiovulate ; style flattened, bearded along the inner 
face. Pod stalked, linear, compressed, dehiscent, many-seeded, the 
faces in our plant plain—Twining or suberect herbs or shrubs witli 
pinnately tri- or multi-foliolate leaves.
