EUPHYCOPHYTA 121 



Chora (of a mountain stream). Figs. 66^ 67 



The genus is very similar to Nitella in its method of reproduc- 

 tion, but the plants are usually larger and coarser, often with lime 

 encrustations. The stem is commonly corticated, the corticating 

 cells arising from the basal nodes of the short laterals, one thread 

 growing up and another down. Another characteristic feature is a 

 single celled corona.
