224 FLORA NIGRITIANA. 
1. Carpolobia lutea, Don, Gen. Syst. 1. p. 370.— Sierra Leone, 
Don; Senegambia, Heudelot. 
Rami graciles, virgati, puberuli, teretes, flexuosi, patentes. Folia 
alterna, subdisticha, breve petiolata, obovata, in acumen elon- 
gatum apice obtusum angustata, glaberrima, integerrima, 
submembranacea, reticulatim venosa, viridia, 2-4 une. longa. 
Racemi axillares, solitarii, breves, 2-5-flori, infra fola orti 
et iis tecti, graciles, } unc. longi, pubescentes. Flores erect, 
3 unc. longi, brevissime pedicellati ; pedicellis basi bracteolatis. 
Sepala 5, ciliata; 3 longioribus ovato-lanceolatis, obtusis, 
cæteris oblongis. Petala calyce ter longiora, in tubum fissum 
basi coalita ; 4 subæqualia, oblongo-spathulata, venosa ; quinto 
carinæformi, duplo majore. Stamina 5; filamentis ad me- 
dium monadelphis. Stylus gracilis; stigmate parvo, capi- 
tato. t

represented (as in P. Donii) by a lobe at the base of the two 
smaller petals. 
2. Carpolobia alba, Don, 1. c.—Sierra Leone, Don. 
The two other species described by Don are leguminous 
plants, which will be noticed hereafter under Baphia and Brac- 
teolaria.* 
XIII. DaosERACE E. 
There are two species of Drosera, from W. Tropical Africa, 
preserved in the British Museum, D. Burmanni, Vahl, and 
D. Indica, Linn. They are both from Sierra Leone (Afzelius), 
and are also natives of India. To the D. Indica, Dr. Plan-
