234 FLORA NIGRITIANA. 
XXI. Tiztacez. 
1. Corchorus éridens, Linn.—Abundant along the West coast 
of Africa, also in the East Indies. 
2. Corchorus acutangulus, Lam. Dict—C. alatus, G. Don, 
Gard. Dict. 1. p. 542, 2. p. 104.—Senegal, Cape Coast, and

G. Don, l. c., p. 543. — Senegal, Quorra, Vogel; St. Thomas, 
Don. : 
A fourth species, C. brachycarpus, Guill. et Perr., occurs m 
Senegal. The three Guinea species, described by Schumacher 
and Thonning, C. angustifolius, C. polygonus, and C. muricatus, 
are probably the same as some of the preceding ones. 
1. Triumfetta rhomboidea, Jacq. Amer. p. 147. t. 90.— Cape

Var. y. foliis omnibus brevi-petiolatis basi ovato-cuneatis.—Cape 
Coast and Accra, Don. 
Also a W. Indian variety, having all the leaves like the upp

berula, subter velutino-pubescentia, superiora basi cuneata, 
inferiora basi latiora; omnia subcordata, obscure triloba. 
Stamina 12 et plura. Fructus deest. 
The plant agrees tolerably with Lamarck's description, except 
the leaves being less velvety. 
3. Triumfetta velutina, Vahl, Symb. 8. p. 62.—Accra, Vogel. 
Differs (possibly not specifically) from T. mollis, in the more 
cuneate base of the coriaceous leaves, which have shorter petioles, 
and are more tomentose beneath; the stems, too, are more
