admit of determining as yet into what other genus the species 
should be placed. 
2. Chrysophyllum obovatum, G. Don, A. DC. Prod. 8. p. 168. 
—Sierra Leone, Dòn, Vogel (?) 
Neither specimen has flower or fruit, and the identity of 
Vogel’s with Don’s is therefore doubtful. The species itself 
remains very uncertain. 
3. Chrysophyllum Africanum, A. DC. Prod. 8. p. 163.—Sierra 
Leone; Fernando Po, Vogel? 
Don’s Herbarium contains no specimen of the Sierra Leone 
plant, and Vogel’s specimens have no flowers. This species 
also must therefore be doubtful. 
The other West Tropical African Sapotacee are Sapota se- 
ricea, A. DC., from Guinea; Siderorylon dulcificum, A. DC., 
from Guinea; Bassia Parkii, G. Don, from. Bambara; and 
Onphalocarpum procerum, Pal. de Beauv., from Oware, most of 
them very imperfectly known.
