This species is widely distributed especially in the Tropics. It occurs in 
southern Asia from India eastwards, in Borneo and in several of the other 
Islands of the Malay Archipelago, also in Africa and in North and South 
America. Like the other widely distributed species it is variable. Braun 
has described two varieties from this region, Belangeri from India, char- 
acterized by its large size, stout stem, and short end-segments to the 
branchlets, and indica from Java and the Philippine Islands, being more 
slender and having longer end-segments. The Trinidad plant is a stout 
foi-m of the latter,

Fairly normal forms of this species, which occurs also in Ceylon, southern 
India, lower Burma, Nicobar Islands, Borneo, Java, Celebes, Sumbawa, new 
Guinea, and Australia (Endeavour River). The closely allied Nitella 
Mauritiana is found in Mauritius. Braun in his later writings applied to 
this species the name of Nitella polyglochin, which he had previously used 
in a wider sense, but there is no valid reason for discarding the earlier name. 
2. CHARA Linn.

Braun described this plant as var.? ba^ilaris on account of the fruits 
being produced at the base only, and not also at the nodes of the branchlets,
