ABSTRACT 



This paper is the seventh in a series of reports on the aquatic and 

 wetland flora of New England. It treats all species of the Cabombaceae, 

 Nymphaeaceae, Nelumbonaceae, and Ceratophyllaceae occurring in 

 New England and includes keys, comments on taxonomy and nomen- 

 clature, habitat and distributional information, water chemistry data, 

 illustrations, and dot maps. Those species regarded as rare and 

 endangered in the New England Region or in one or more of the six 

 New England States are also noted. One species, Nymphaea tetragona, 

 is presently under consideration by the U.S. Fish and Wildlife Service 

 for listing under the Endangered Species Act of 1973.
