FRESHWATER ALGAE FROM INDIA, r 283 
SSS 
This peculiar species was fruiting abundantly in No. 31090, but the zygos- 
i The vegetative cell has three or 
four chloroplasts with two to two and a half turns and the cell becomes very 
swollen. The alga in No. 31090 was very similar to S. Grossi Schmidle, but 
the vegetative cells are a little wider, as are also the fruiting cells. The zygos- 
pores in this sample were also too young to show the character of the wall 
described by Schmidle. The Alga in No. 93039 was more typical.
