MR. G. BENTHAM—REVISION OF THE GENUS CASSIA. 531 
former from the other subsections of Chamefistula. But now that the allied species are much better 
known, we find that this absolute reliance upon the pod and seeds would widely separate C. occidentalis 
from C. Sophera on the one hand, and from C. ligustrina and its allies on the other, which are so closely 
connected with it that Vogel himself, as well as many others, have doubted whether they may not be 
varieties ; whilst of the five species collected together by Vogel as forming the subsection, only two strictly 
belong to it; for one of the others, C. cana, which he had not seen, proves to belong to Prososperma, 
another, C. tomentosa, has often the pod quite like that of some varieties of C, bicapsularis, and the third, 
C. ruscifolia, appears to me to be a cultivated form of C. Sophera. It has appeared to me that a much 
more natural and better-defined group can be obtained by taking the basal gland on the petiole below 
the leaflets as the essential character distinguishing it from all others of the subgenus Senna, the pod 
having an intermediate character between those of Chamefistula and Chamesenna, passing in several 
species, especially in C. occidentalis itself, from the one to the other. The only species somewhat am- 
biguous as to the gland are C. oblongifolia, in which a single leaflet, or even a pair, are sometimes 
developed at the gland, and C. bahamensis in Chamasenna, where the lowest pair of leaflets is sometimes 
though rarely deficient, leaving the gland on the petiole as in Oncolobium. These two species are in other 
respects allied to each other, and connect the two sections.

Hab. Tropical America : Brazil, prov. Rio J aneiro and Minas Geraes, and a narrower-

northern and western specimens belonging to the hirsute variety. ; 
The long linear pod of this and the preceding species are like those of several species of Prososperma ; 
but the transverse or oblique seeds, as well as the gland, are those of Oncolobium. Wright's New-Mexican 
specimens (n. 1032) are glabrous, and closely resemble those from Rio Janeiro. vee
