Much more restricted in range than the last and chiefly confined to 

 rocky thickets in Ontario, abundant at Belleville and in the valley of 

 the Moira ; also at Trenton Station and in the Trent Valley nearly up 

 to Oampbellford. {Macoun.) Plentiful in the vicinity of Toronto. 

 {A. Fowler.') Low sandy thickets, London, Ont., also at Emerson, 

 Man. {Burgess.) In thickets near Selkirk, Man. (J. M. Macoun.) 

 Abundant in thickets at Winnipeg, and westward in thickets up the

Q. alba, var. repanda, Pursh, Fl. I., 633. 



Q. alba, var. mierocarpa, DC. Prodr. XVI., 22. 



One of our most widely distributed oaks, being found mixed with the 

 white pine in western Quebec and eastern and northern Ontario, and 

 reaching an immense size in the western peninsula. On sandy plains 

 and sand or gravel ridges, it often constitutes over half the foi'est, but 

 in low rich soils, it is seldom seen. 



(1992.) Q. Carryana, Douglas. Western White Oak. 



Q. Douglasii, var. ? Need, DC. Prodr. XVI., 24. 



Abundant on the south-eastern part of Vancouver Island, especially 

 in the neighborhood of Victoria, where it occupies large tracts of rocky 

 ground. Seen furthest north on prairies along the river at Comox. A 

 few small trees, a mile and a half above Tale on the Eraser, B.C.

Q. steaata, Wang. DC. Prodr. XVI., 22. 



We have never been able to fully identify this tree in southern Ontario, 

 but admit it on authorities given below. A tree with fruit agreeing 

 with Michaux's figure grows along the Bay of Quinte and is possibly 

 this species. (Macoun.) Canada. (Dr. Beck, vide Soaker.) Southei-n 

 Ontai'io. (Sargent.)
