9. Tephrosia linearis, Pers. Syn. 2. p. 330.—Senegal ; Accra, 
Vogel; also a native of Cordofan. 
The genus Tephrosia seems peculiarly abundant towards the 
northern or drier regions of West Tropical African Flora, all 
but one of the following additional known species being found 
in Senegambia, viz.: 1. T. bracteolata, Guill. et Perr., and 2. 
T. platycarpa, Guill. et Perr., both from Senegal ; 3. T. humilis, 
Guill. et Perr., from Senegal and Cape Verd ; 4. T. apollinea, 
DC., from Senegal ? Nubia and Arabia ; 5. T. leptostachya, DC., 
from Senegal and Nubia; 6. 7. /ineata, Schum. et Thonn. 
(perhaps the same as T. leptostachya, DC., and T. purpurea, 
Pers.) from Guinea; 7. T. gracilipes, Guill. et Perr., from Se- 
negal; 8. T. uniflora, Pers. (to this may possibly belong the 
Senegambian T. apollinea, as well as the T. anthylloides, Hochst.; 
the true Galega apollinea, Delille, being probably a very different 
species), Senegal and Nubia; 9. T. lathyroides, Guill. et Perr., 
from Cape Verd; 10. T. hirsuta, Schum. et Thonn. (perhaps, 
as well as T. lathyroides, the same as T. uniflora) from Guinea; 
11. 7. digitata, DC., from Senegal ; and one, or perhaps two, 
unpublished species from Senegambia. 
The T. toxicaria, presumed by Tussaud to have been intro- 
duced into the West Indies from West Africa, does not appear 
in any of the collections from the latter country, where other 
species are cultivated for the same purpose of poisoning fish. 
It may also be stated, as further evidence that T. ¢owicaria 1s 
really American, not African, that the American Continent pos- 
sesses other indigenous species much nearer allied to that one 
than to any African ones. 
1. Sesbania aculeata, Pers.—Accra, Vogel; Senegambia, and 
widely diffused over Africa and the East Indies, and intro- 
duced into the West Indies. 
2. Sesbania Ægyptiaca, Pers.—8. punctata, DC.—Sierra Leone 
and Quorra River, at Attah, Vogel; Senegambia, and, like
