* 1. Manihot ulilissima, Pohl.—Jatropha Manihot, Linn. var. ? 
heterophylla.—Grand Bassa, Vogel, cultivated. 
This variety of the Cassava is the one described by Thonning 
as commonly cultivated in Guinea. It is not precisely identical 
with any of those distinguished by Pohl, but probably with 
the M. Aipi; and perhaps one or two others of that author 
should be included in one species, which must necessarily have 
Varied much by the effect of long and extensive cultivation in 
all Tropical regions. 
l. Jatropha multifida, Linn. —Sierra Leone, Vogel. 
3. Hen gossypifolia, Linn.—Cape Coast, Vogel; Accra, 
on. 
Both the above are South American plants, either introduced 
or cultivated in Africa, as is also the Curcas purgans, Med. 
(Jatropha Curcas, Linn.), said by Thonning to be found here 
: and there in Guinea.
