Mn. BzxrHAM has well observed * that the genus Dolichos had 
been, up to the publication of DeCandolle’s * Prodromus, a 
receptacle for many of the obscure Phaseolew; and I may add, 
for long after that period; for, of the nine species published in 
the ‘ Prodromus’ of Wight and Arnott, about one half belong 
to other genera; and among these I venture to place Dolichos 
uniflorus, Lam. This is by no means an obscure plant, being 
extensively cultivated in India under the name of Kooltee, and 
used for feeding cattle. Up to the present time every author 
appears to follow Lamarck in placing this plant under Dolichos. 
The published descriptions of this plant are not altogether 
accurate. Roxburgh, in his ‘Flora Indica,’ states that two 
bracts press the calyx laterally, and that the upper lip of the 
calyx is emarginate; while Wight and Arnott describe the calyx 
as deeply bilabiate, and the stigma as glabrous. The bracts do 
not press on the calyx, but are scattered on the pedicels ; the upper 
segment of the calyx is shortly split into two setaceous teeth; 
and the vexillum is obovate-oblong. There is not the slightest 
approach to a bilabiate form in the calyx; and the stigma is sur- 
rounded, not exactly by hairs, but by tubes incurved at their 
apex, not unlike the tentacula of some Actinia. Roxburgh .al- 
ludes to the absence of eallosities on the vexillum ; and there are 
certainly no callosities properly so called; but there are two very 
narrow membranous expansions, with free margins, occupying the 
usual position of the callosities; these appear, however, to be 
of a peculiar nature, and unlike any thing I have seen in the 
Leguminose. 
The simple unknotted rachis, the calyx with long, slender, 
subulate teeth, much longer than the tube, the narrow mem- 
branous vexillum without callosities, auricles, or thick-edged 
claws, the narrow straight linear wings, slightly curved keel, the 
hitherto unobserved adherence of the tenth stamen to the sta- 
minal tube, the long, filiform, slightly curved, glabrous style, 
and the absence of a glandular sheath round the base of the
