 Ch. Bellangeri A. Br. in lit. 



In pools near Gengu on the coast of Coromandel, collected by 

 Bellanger in 1826-28, growing in company with Char a coronata, var. 

 Coromandelina. 



This species resembles, in size and habit, Nitella translucens, being 

 however entirely différent from it in its only one-celled segments of 

 the leaves, and in reality much nearer N. flexïlis. The fructiferous 

 heads are larger and less dense than in N. translucens. The nut 

 of the seed is yellow-brown, and 2 y^° m. long. 



Another variety of this species is fourid in Missouri and Texas (N. 

 acuminata var. Lindheimeri) and a third in the Isle de France (N. acu- 

 minata var. Mauritianaff
