ENUMERATION OF LEGUMINOS;E, 57E 
of the group of Alate, imperfectly figured as to the inflo- 
rescence. 
C. acuminata (DC. Prodr. 2, p. 128) of which I have seen 
a small specimen of Dr. Burchell’s. with a single flower, is 
certainly not a Crotalaria. In this specimen one of the leaves 
is pinnately trifoliate, the others are unifoliate. The plant 
has the appearance and the leaves the venation of a. Tephrosia, 
but the carina is spirally twisted, as in Phaseolus, to which 
genus it certainly does not belong. It probably forms a 
new genus; but the specimen is insufficient to describe it. 
Series II, FoLroLarÆæ. Foliola ad apicem petioli articulata, 
in $ 8 ad 17 terna v. rarius solitaria, in $ 18 plurima v. omnia 
quina vel septena. 
$ 8. Chrysocalycine. Racemi terminales dense spiciformes 
v.capituliformes. Legumen oligospermum, globosum v. ovoi- 
deum, calyce demum aucto brevius v. vix longius. Foliola seepe 
ineequalia v. interdum solitaria, petiolo abbreviato.—Chryso- 
calyx, Guillem. et Perrot.—Species omnes hie enumerate. 
In some species of this group, as in C. paniculata and 
some others allied to it, the young pod is slightly compressed, 
especially at the apex, but not sufficiently so to remove them 
from the genus. All other characters appear to me to be 
precisely those of Crotalaria.
