Dry rocky fields and thickets extending from the western part of 

 Quebec to Manitoba, near Brandon on the Assiniboine. Nicolet, Q. 

 {Maclagan) is its eastern limit. Although called Downy Arrow-wood, 

 it is often almost smooth, and approaches closely to the preceding 

 except in its short petioles which are constant.

Dry rocky thickets and borders of woods. Beloeil and Montreal 

 Mountains. {McGill Coll. Herb.) Common in Ontario. {Macoun.) 

 From Lake Huron to the Saskatchewan. {JDrummond.) This species 

 is reported from Newfoundland, Nova Scotia and Alaska, but, as it was 

 formerly confounded with the next, I believe these references belong 

 to that species
