CATALOG OF AQUATIC PLANTS 



THALLOPHYTA 



CHARACEAE Muskgrass family 



1. Chara L. 



Chara spp. — No attempt will be made to differentiate here the 

 species of Chara, nor will it be attempted to distinguish Chara from 

 the related Nitella (not listed). This list was designed to include 

 primarily the vascular aquatic plants, and Chara is included because 

 it has characters which make it simulate vascular species and because 

 Anopheles qvudrimaculatus is sometimes found associated with it.
