We have long possessed what we consider the same species 

 as that of Van Dieman's Land from the Lachlan River, gathered 

 by Mr Allan Cunningham. His specimen is however larger, 

 and the leaves are all more or less dentated. But it is well 

 known how variable is the foliage of many aquatic plants.
