ENUMERATION OF LEGUMINOSX. 339 
1. R. trifoliata (Pers.—W. et Arn.! Prodr. 1, p. 195 cum 
syn. omn.) 
Apparently a common plant in the East Indian Peninsula 
but I have not seen it from any other locality. 
XX. Xerocarpus, Guillem. et Perrott. 
Another single species, a small plant with the habit and 
all the characters of Rothia, excepting the pod, which, al- 
though it opens in the same manner, is very different in 
form. 
1. X. hirsutus, (Guillem. et Perrott! Fl. Seneg. 1, p. 170, 
t. 44.) 
Tropical Africa. Sandy hills near Kouma in the Walo 
country, Leprieur and Perrottet ! Cordofan, Kotschy ! n. 420. 
XXI. AnavnoronivM. Eckl. et Zeyh.—Chasmone, E. Mey. 
—Trichasma, Gamochilum et Argyrolobium, Walp. 
_ This genus, as limited by E. Meyer as well as Ecklon and 
Zeyher, and adopted by Meissner, Spach and others, is a na- 
tural one, and readily known among Genistee by the calyx of 
a Dichilus with the corolla nearly that of Crotalaria and a 
pod not unlike that of some Zephrosie. It has however 
been divided by Walpers into three, according to the depth 
to which the calycine lobes are separated, but this character 
does not appear to be in sufficient conformity with habit, nor 
even constant enough in the same species to be available 
Sven for sectional divisions.* The Cape species have been 
* I regret much the differing so widely in opinion as to the circumscrip- 
tion of Leguminous Genera from Dr. Walpers, whose compilations, and 
especially his Repertorium, are of so much use in abridging the labour of 
hunting out published species, Where we differ as to the synonymy of the 
distributed Cape colleetions, it may sometimes have arisen from mistakes 
qo the distribution of the specimens.’ Thus, when Dr. Walpers asserts that 
Iam quite wrong ('* vehementer errat") in referring the Ingenhoussia roses, 
^^ Mey. to Coelidium, for that it is nothing -but re densa; it is
