County, Curtiss 104. 
Although related to Nymphaea sagittifolia the Florida plant 
may be distinguished by its much wider, more pointed leaves, 
its smaller fruit, and its elliptical stigma rays. The submersed 
leaves when dried strongly suggest specimens of certain alge, 
especially the genus Ulva, hence the specific name.
