FLORA NIGRITIANA. 309 
Herba volubilis, V. gracili affinis, sed omnibus partibus major. 
Rami hine inde pilis reflexo-patentibus hirti v. omnino gla- 
brati. — Stipule 1-2 lin. longe, late lanceolate, acute, striate, 
basi in auriculam brevem acutam infra insertionem producte, 
glabre v. piloso-ciliate. Petioli infra foliola 2-3 poll. longi, 
inter foliola semipollicares, hine inde presertim prope basin 
patentim pilosi. S/ipelle parve, obtuse, fere glanduliformes. 
Petioluli 1-14 lin. longi, villosi. Foliola 11-3-pollicaria ; 
terminale late rhombeum, lateralia valde inzquilatera, basi 
truncata v. subcordata, omnia apice breviter acuminata, utrin- 
que viridia, margine ciliata, ad costas pilis nonnullis utrinque 
hispidula et in pagina superiore pilis raris conspersa. Pe- 
dunculi infra flores 3-5-pollicares, parte florida 14-2-polli- 
cari. Pedicelli ad quemquam nodum gemini v. rarius 3-4-ni, 
per anthesin calyce seepius breviores, fructiferi paullulum elon- 
gati. Bractee et bracteole parve, oblongo-lineares. Calyx 
fere V. glabre nisi dentibus latioribus multo obtusioribus. 
Petala glabra, iis V. glabre subsimilia. Legumen 15-18 lin. 
longum, vix 2 lin. latum. > ; 
Like the V. gracilis, this species cannot be generically sepa- 
rated from the T. glabra of Savi, which is much nearer to the 
true Dolichos than some of the following. Unfortunately, the 
very indifferent specimens existing in herbaria, scarcely admit 
as yet of any exact limitation of this and the allied genera. 
8. Vigna? sp., apparently near V. multiflora, but the specimen 
is too bad to determine.—Near the town of St. Ann de Chiaves, 
Don. : 
4. Vigna unguiculata, Walp. Rep. 1. p. 779.—Dolichos ungui- 
culatus, Linn. et Auct—Cape Coast, Vogel.—Extensively 
cultivated in W. Tropical Africa, as it is in other parts of 
Africa, Asia and America. É 
5. Vigna linearifolia, Hook. fil. ; caule volubili scabro v. piloso, 
stipulis lanceolatis acuminatis pilosis, petiolis hispidis, foliolis 
longe lineari-lanceolatis hispidulis transverse reticulatis, pe- 
dunculis pilosis apice 2-3-floris, calycis laciniis 5 longe lan- 
ceolato-setaceis, legumine densissime velutino-villoso.— Sa- 
vannahs of the Quorra, Vogel.
