Two very marked forms were found growing together at Black 



Eapids, Eideau Eiver, near Ottawa, by Mr. Fletcher. Of these forms 



Mr. Morong writes him : — 



(I.) " There is no varietal name for this form, but it is bushy and 



densely clothed with fine setaceous leaves, and might be called var. 



tenuissimus, as you suggest. 



(II.) This form approaches the " var. (?) latifolius" of Bobbins, 



some of the leaves three nerved."
