Mr. Nuttall, who has revived or established this species, remarks that it 
is perfectly distinct from the H. simplex of Michaux, as the latter produ- 
ces oblong ovate leaves, partly connate at the base, and always pressed 
close to the stem, and the whole plant instead of being pilose, is covered 
with a short matted and somewhat scabrous pubescence. (Nutt. loc. cit.) 
1 doubt, however, whether Walter did not mean by his H. pilosum the H. 
simplex of Michaux, as he mentions the appressed leaves as a part of its 
character, or, perhaps, as has heretofore been done, he confounded both 
under that name ; if however I have not mistaken this plant, I must add
