whether the following spechuens really all belong to S. Drummondiana, but 

 I hope that we shall soon get more eopious material from such frequently 

 visited ]>laces as the vicinities of Banff and Laggan in Alberta. This species 

 is mentioned by Macoun (1885) also from '*on the beds of snow-slides, sum- 

 mit of the Selkirk Mountains, B.C." but I have not yet seen specimens from 

 there. J. K. Henry (1915) does not cite a definite locality. 



Hooker also mentions a form **/3. ovariis glabris." He does not cite a 

 tyi)e, and states that in /S the pistds are quite glabrous, and that *'in this 

 var. the silky hairs of the scales arc longer than in the usual state of the 

 plant." Andersson said (1867) that he did not see a specimen belonging 

 to this variety, neither have I.

I ani not sure whether McCalla's specimens j^resent the real S. Druni- 

 luondiana or the same form as the following s])ecimens whicli jiartly look 

 like S. Jepsonii, and to which I wish to draw the special attention of col- 

 lectors and students.
