FLORA NIGRITIANA. Bis 
inferiore ceteris triente majore. Vewillum calycem superans, 
oblongum, basi biaurieulatum ; ale anguste, vexillo bre- 
viores, carinze breviori coheerentes. 
Closely allied to the East Indian R. densiflora, it differs 
chiefly in its much smaller calyces. 
The other W. Tropical African species are: 1. R. minima, 
DC. from Senegambia and Guinea, a common Tropical plant in 
_ both hemispheres; 2. R. caribea, DC., a West Indian plant, 
found also in Senegal and Guinea, unless the species alluded to 
under that name in African Floras, be rather the R. Memnonia ; 
3. R. faginea, Guill. et Perr., from Senegambia, a species 
which should perhaps be transferred to Eriosema or Arcyphyl- 
lum ; and 4. R. argentea, Desv., from Angola, which is entirely 
unknown to me. —
