FLORA NIGRITIANA. 439 
This species is certainly interniediate between the three 
preceding and the East Indian Gynure, the corollas are not so 
slender as in the former, and always all alike, and not so thick, 
although more numerous than in most Gynure. Their colour 
is different from that of the generality of species in which it is 
recorded, 
1. Emilia sonchifolia, Cass. -DC. Prod. 6. p. 302.—Sierra Leone, 
Don.—A common East Indian and Tropical African plant, 
which has become naturalized also in some parts of America. 
The almost universally prevalent genus, Senecio, is repre- 
sented in West Tropical Africa by two species only, S. strictus, 
DC., and S. Perrottetii, DC., both from Senegal; and the 
two large sub-orders of Carduacee and Labiatiflore by three 
Species, two of Centaurea, C. Perrottetii, DC., and C. Sene- 
galensis, DC.; and one of Dicoma, D. tomentosa, Cass. ; all 
also from Senegal. 
l. Cichorium Intybus, Linn.—St. Thomas, Don ; to all appear- 
ance identical with the common European plant. 
The other Cichoracee from West Tropical Africa are: Picris 
humilis, DC., from Senegal; Lactuca taraxacifolia, Schum. et 
Thonn., from Senegal and Guinea; Brachyramphus Goreensis, 
DC., and Rhabdotheca Brunneri, Webb, both from Senegal. 
z LXVI. CAMPANULACEÆ. 
Of this Order there are no specimens in the collections before 
us, nor does it appear that any have been found within the hot 
regions of Guinea and the Niger, although Senegambia has 
furnished five, Lobelia Senegalensis, A. DC., Cephalostigma 
Perrottetii, A, DC. C. Prieurii, A. DC., Wahlenbergia ri- 
Paria, A.DC., and JW. cervicina, A. DC., the latter species 
extending also into Egypt.
