calyci flora:. 
indicated in debility of the stomach and bowels, attended with 
flatulence or acidity. The analysis of 20 parts of Cassia gives, 
according to Henry: sugar 12.20; gum 1.35; tanning matter 
2.65 ; traces of gluten (?) ; a small proportion of colouring 
matter ; water and loss 3.80. 
The roots of this tree are branched, smooth, and large, and 
contain a bitter principle, said to be febrifuge, and capable of 
being employed as a substitute for Quinine. M. Caventou, who 
made some investigations into the subject, regards it as a 
powerful diuretic, and found that, like rhabarbarin and colocyn- 
thine, it forms combinations, slightly soluble, with sulphuric, 
nitric, and muriatic acids. 
The seeds of the Cassia, in the dose of 4-6 drachms, are pur- 
gative. The flesh of animals, which have fed on the leaves, is 
also said to acquire this property. 
Sect. 2. Sepals very obtuse. Anthers biporose at 
the apex. Legumes terete , scarcely dehiscent , 
thin, membranaceous , multilocular with transverse 
partitions ; cells sparingly supplied with pidp : 
seeds horizontal. 
3. * Cassia melanocarpa. Black-podded Cassia.

Sect. 3. Sepals subobtuse. Anthers biporose. Le- 
gumes with the valves furnished with an acute 
foliaceous wing , many-celled by transverse parti- 
tions ; cells subpulpose : seeds horizontally placed, 
compressed , in general obcordate. 
4. Cassia alata. Ring-worm Shrub. 
Leaflets 8— 12-paired, lower ones in general lineari-
