The number of the leaves of the whorls varies from 4 to 11, 
the length of the air leaves is between 5 and 12 mm., the breadth 
1,5—2 mm., the water leaves vary between 5 and 12 mm. (length) 
and 1,5--3 mm. (breadth), and these variations may appear together 
in the same specimen in all combinations. It is therefore impos- 
sible to distinguish between the main form and f. maritima (Hellen)
