 This variety is very distinct from the species if the form of the leaf 

 only is considered. The St. Clair specimens have leaves fully eight 

 inches long and not at all cordate at the base. Many of the references 

 given with the species very likely belong here, but we have no means 

 of determining without the specimens. Shallow water, Norton, N.B.
