302 FLORA NIGRITIANA. 
Reich. DC. Prod. 2. p. 316.—Z. biarticulata, G. Don, Gard. 
Dict. 2. p. 288.—Accra, Vogel, Don ; Senegambia. 
The distinctions between the common American, Asiatic and 
African forms of this widely diffused plant prove to be very 
inconstant, as already observed by Vogel ; and it is now no longer 
possible to view them as forming more than one species, found 
in almost every hot country visited by botanists. 
A new species of Geissaspis, remarkable for its entire, not 
ciliated bracts, is amongst Heudelot’s Senegambian plants. 
The same Senegambian collection includes the Herminiera 
elaphroaylon, Guill. et Perr., which must be removed to Hedy- 
saree, the pod being certainly articulated when quite ripe, and 
an allied plant, which appears to be the same as the Abyssinian 
Acrotaphros bibracteata, Steud.

2. Ormocarpum coronilloides, G. Don, Gard. Dict. 2. p. 279; 
folis impari-pinnatis, foliolis multijugis oblongis utrinque

glanduloso-puberulis, St. Thomas, Don;-—var. f. petiolis 
pedicellisque glabrioribus, on the Niger, Mc William. 
Very similar to a Philippine Island plant, which appears to 
be the ZEschynomene colutoides of A. Richard, and which as 
well as our plant, may be mere varieties of the East Indian O. 
sennoides, the degree of glandular hairiness of the inflorescence 
and pods being evidently very variable. 
1. ZEschynomene aspera, Linn. DC. Prod. 2. p. 320.—Nun 
and Quorra Rivers, Vogel; Accra, Don. These specimens 
differ but slightly from the common East Indian form m 
the bracts and calyxes being more acuminated and smooth, 
but do not appear to be specifically distinct.
