200 XLVII. § PAPILIONACEE (BAKER). [ Vigna. 
America. By the recurved point of the keel, spp. 11-14 recede from typical Vigna in the 
direction of Phaseolus. A plant from Zambesi land, gathered by Dr. Kirk, with more 
coriaceous leaves and more densely hispid leaflets, calyx and pod, is perhaps distinct. 
Var. 8. V. Thonningii, Hook. f. Fl. Nigr. 311. Stem trailing. Petioles {-1} in. 
Leaflets broader and shorter, the end one ovate or obovate, 2-3 in. long. Calyx less 
hairy, less than half as long as the corolla. 
Upper Guinea. Cape Coast and Fernando Po, Vogel! 
A trailing coast form. 
Lower Guinea. Mossamedes, Dr. Welwitsch ! 
Var. y. V. angustifolia, Hook. Fl. Nigr. loc. cit. Whole plant subglabrous; leaflets 
lanceolate, much smaller; the end one 2-3 in. long, 4-4 in. broad; flowers smaller ; 
calyx subglabrous. 
Upper Guinea. Guinea proper, Thonning, Barter! 
14. V. phaseoloides, Bulker. Stems slender herbaceous wide- 
climbing clothed with soft short pubescence. Petioles short ; leaflets 3, 
subscabrous above with inconspicuous bristles, pale green and finely 
downy all over below; end one obovate acute 3—3} in. long; lateral 
ones very unequal-sided. Flowers 2-4, subsessile on the apex of a 
downy peduncle 1-4 in. long. Calyx 2in., finely downy; teeth lan- 
ceolate acuminate as long as the tube. Corolla 1 in., reddish-purple, 
veined; keel with a long recurved beak. Pod linear, 4—4} in. long, 
nearly straight, finely downy. 
Lower Guinea. Pungo Andongo, Dr. Welwitsch! 
Differs from V. vexillata principally in the texture of the leaves and nature of the 
pubescence. 
15. V. hastifolia, Baker. Stem firm-herbaceous, twining, per 
manently clothed with fine short white pubescence. Stipules minute, 
lanceolate, silky. Petioles firm, 1-3 in. long. Leaflets 3, the central 
one hastate, bluntly lobed halfway down from the edge to the midrib, 
the point blunt, the base subcuneate, its petiolule 4—12 lines long, the 
lateral ones usually similarly lobed on the lower side only, texture sub- 
coriaceous, the upper side thinly and the lower densely clothed with 
adpressed white cottony hairs. Flowers (always ?) solitary on later 
pedicels 3—4 lines long. Calyx campanulate, 4 lines deep, densely silky, 
the blunt subdeltoid lobes not reaching half down. Flowers pale yellow, 
turning yellow as they fade, very fragrant, 8-9 lines deep, and standar' 
8—lines broad. Pod linear, faa, 4—5 in. long, 3—4 lines broad, 
persistently clothed with adpressed white-silky hairs, 12-15-seeded. 
Upper Guinea. Nupe, and Jeba, Barter! 
This may be Dolichos argenteus, Willd., DC., Prod. ii. 399, a Guinea plant which we 
are not able to identity more certainly. 
16. V. holosericea, Welw. mss. Stems wide-twining, densely 
clothed with soft spreading whitish tomentum. Stipules minute lan- 
ceolate not spurred. Petioles 1-2 in., densely pubescent; leaflets 3, 
rather thick, soft, matted especially below with grey tomentum ; eM 
one oblong-rhomboidal, 2-8 in. long, rounded at fhe base, blunt with a 
mucro ;, petiolule 3-4 lines; lateral ones unequal-sided. Flowers soli- 
tary on densely pubescent peduncles $2} in, long. Calyx $in., densely
