Lesquerella occidentalis, Wat. 



Dry slopes Osoyoos Valley, B.C., 1898. (C. de B, Green.') 

 New to Canada. 



Viola subcordata, Greene, Pittonia, vol. 111, page 316. 



Open or partly open land, Esquimault, Vancouver Island, 6th 

 June, 1896. Herb. No. 18,708. ( /. R. Anderson.) A beautiful 

 species nearly related to V. HowelliL. Known only from the above 

 locality. 



Viola subvestita, Greene. 



On the cliff below Governor's Bay, Ottawa, Ont., 1899. {J. 

 M. Macoun.) 



Viola sagittata, Ait. 



We have no true V. sagittata in Canada, at least none of the 

 specimens in our herbarium are referable to that species. All 

 specimens so named are either V. cvrt!/«,.Nutt, or V. deutata, Pursh. 

 which may, however, yet prove to be one species. 



V. OVATA, Nutt. 



V. sagittata, Macoun, Cat. Can. Plants, vol. i, p. 63 in part. 



Our herbarium specimens are from dry fields east of Belleville, 

 Ont. [John Macoun.) Near Hamilton, Ont. {J. M. Dickson.) 

 Strathroy and woods about London, Ont. {J. Dearness.) 



V. DENTATA, Pursh. 



V. sagittata, Macoun, Cat. Can. Plants, vol. i, p. 63, in part 

 and vol. i, p. 492.

 [John Macoun.) London, Ont. [Dr. Milinian.) Komoka, Ont. 

 and London, Ont [J. Dearness.) Port Flamboro, Ont. (/. M. 

 Dickson.) Thoug-h kept separate here it is more than probable 

 that V. ovata and V. dentata are forms of the same species. 



Viola SEPTENTRiONALis, Greene, Pittonia, vol. 11 1, p. 334, and 

 Ott. Nat., vol. XII, p. 183.
