tinged with reddish purple. Lomentum composed of many (J — 10) ve- 
ry indistinct joints, very hispid. ^ ^ 
I have had no opportunity of examining this plant m a living state; it is 
said by Pursh, on the authority of the herbarium of Gronovius to be the 
original Hedysarum Yirginicum of Linnaeus. It scarcely can be arranged 
with that genus, but I think also with M. Nuttall, that it cannot remain 
jn the same genus with the preceding species. 
Grows in damp and marshy soils. 
Flowers July and August.
