Native of North America throughout the eastern and prairie dis- 
tricts to near the Arctic sea, upper Louisiana, &c. Never ob- 
served floating in deep water, but sometimes spreading over the 
surface of sphagnous bogs, more generally creeping on mud in 
very sheltered pools of water, in shady places. Flowers yellow. 
This aquatic plant has a very similar habit with R. aquátilis, and, 
like it, varies exceedingly in the length of the stems and the 
shape of the leaves, according to its situation in deep or shallow 
water, in more or less flowing streams, and on the almost dry mud.
