Nymphaea fluviatilis seems nearest related to N. macrophylla 

 Small, a species said to range from Florida to Louisiana, from 

 which it differs principally in its much slenderer rootstocks, longer

 whether the leaves of N. macrophylla are floating or emersed, but 

 it is certainly not known to have any submersed leaves. It is 

 almost superfluous to compare N. fluviatilis with the other south- 

 eastern species ; but it differs from N. advena in having its princi-
