It agrees entirely with the figure of * E. Caffra,” Reichen- 
bach, Flor. Exot. 5, t. 312, which we must distinguish as a 
peculiar species, or at least as a remarkable variety, differing 
from Æ. Caffra, Thunb. and E. Mey. (comm. p. 149), in the 
aculeate petiole and folioles, and in the long raceme, form of 
the calyx, vexillum, ete. In this point our plant agrees with 
E. Humei, E. Mey. to which is referred E. Caffra, Ker in 
Bot. Reg. t. 736, Bot. Mag. t. 2431, DC. prodr. 2, p. 412 
but this, as well as E. acanthocarpa, E. Mey., both which 
we have seen, differ in the form of the calyx, folioles, etc. 
The name we have chosen, alludes at once to the aculeate 
leaves and to the form of the folioles which resembles that 
of some of the well known genus Raja among fishes. The 
aculei are whitish at the broad base, and brown at the re- 
curved end ; on the petiole they are numerous, while on the 
folioles only 4-6 occur on the middle nerve and still fewer on 
the lower secondary and tertiary nerves or veins, the upper 
surface has but one or two short aculei, or is sometimes.
