In both varieties the flowers are. pentamerous, and in the 
seeds of the first variety at least, the cotyledons are thin and 
convolute. 
The only other W. Tropical African species is the P. aculeata, 
DC., from Senegal, which is also found in Cordofan.

Leone, Don. 
The bases of the petioles remain on the branches, and harden 
into thorns, as in most Poivree ; but the flowers are tetramerous, 
and the cotyledons fleshy and not convolute. As in all the 
Combreta and Poivree l have examined, the seed is marked 
With as many angles as the fruit has wings, and even the 
embryo is moulded as it were into the same form, for the angles 
retain their position with regard to the seed, whatever be the 
texture or arrangement of the cotyledons.
