supra-axillary, very short; flowers rather larger than in wictitans ; 
legumes usually in pairs, hispid, somewhat obtusely linear, 2.8 cm. 
long, .6 cm. wide; seeds few, oblique.

It seems to be the result of carelessness on Bentham’s part that — 
he has inserted C. aspera Muhl. as a synomyn of C. nictitans L. 
Even if the differences were not sufficiently well marked to war- 
rant the establishment of a species, there could be no doubt — 
whatever that they constituted a varietal distinction. But aspera 
has hispid stems, while méctitans is glabrous; the petiolar gland in 
the one case is slender and elongated, in the other urceolate, sub- 
sessile; aspera produces pods in pairs, while sictitans does not. 
C. aspera bears a much closer resemblance to the Cuban C. patel- 
laria D.C. than it does to mictitans ; and the differences are harder 
to detect. In fatellaria, however, the venation is radically differ- — 
ent, the costa adjoining the superior margin of the leaflets, while 
in aspera it occupies very nearly a medial position. C. patellaniais 
‘downy-pubescent, not hispid, the flowers are smaller and sessile.
