This a very marked, and as the genus goes an apparently fairly 
constant species. Its allia ance is no doubt with D. fluitans, but in 
habit and structure it differs widely; it has rather long, fastigiate 
branches, with leaves not at all faleate, and resembles very strongly 
some of the more slender species of Fontinalis. The leaves resemble 
those of D. fluitans, but are much shorter and wider in the points; 
the nerve is short, and the alar cells are scarcely at all differentiated.
