Mr. Nuttallj who has revived or established this species, remarks that it 

 is perfectly distiiict from the II. 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. cic.) 

 I doubt, however, whether Walter did not mean by his H. pUosum the H. 



simplex of Michaux, as he mentions the appressed leaves as a part qf its 

 character, or, perhaps, as has heretofore been done, he confoimded both 



undei: that name ; if howeyer I )iave not mistaken this plant, | m^st ad^4
