This genus, in its artificial character, agrees very nearly with^ the pre- 

 ceeding, it differs however in its calyx, its germ, and very much in its ha- 

 bit, and may with propriety be kept distinct. 



This plant was the original Glycine of Linnaeus, and ought to have re- 

 tained the name. The tubers formed an article of food to the Aborigine^s 



of this country- 

 Grows in damp rich soils, along the margins of swamps. 



Flowers July — August.
