The C. MdrUandioa, a plant very common throughout the Southern States, and 

 known by the name of American Senna, possesses the properties of the imported Sen- 

 na, which is from plants indigenous to Egypt and Arabia, and is the product of several 

 species of Cassia It is a mild cathartic, owing this effect to a substance obtained by 

 the analysis of Lassaigne, and called Catharti'n. 



Gems XLVIL— GLEDIT'SCHIA. L. 20—6. 

 (In honor of Gleditsch.) 



Flowers dioecious or polygamous. Calyx consisting of 3 — 5 

 — 8 sepals, united at the base. Petals equal in number to the sep- 

 als, or fewer. Stamens generally equal the sepals, occasionally 

 fewer by abortion. Stigma pubescent. Legume compressed, 

 stipitate. Seeds oval, testa crustaceous. Trees with pinnate 

 leaves, and generally spiny branches. 



1. G. triacan'thos, (L.) A large tree, wood hard, generally bearing 

 compound spines. Leaves pinnate; leaflets lanceolate-oblong, glabrous, 

 slightly crenulate near the summit. Flowers in axillary racemes. Le- 



falcate, 12 — 14 inches long, slightly twisted, mucronate, many- 

 seeded; the spaces between the cells of the seed filled with a sweet 

 pulp. — Greenish. ^ . May. In rich soils. 50 — 60 feet.
