CATALOGUE OF CANADIAN PLANTS. 191 



Tar. major, K". Var. 



Abundant in the foot-hills of the Eocky Mountains, at Morley, and 

 westward to Donald, in the Columbia Valley. (Macoun.) This form 

 exactly matches Scribner's No. 341 from Montana, but is quite 

 unlike our northern and eastern specimens. 



(2740.) S. spartea, Trin. ; Gray, Man. Ed. V., 617. 



Very abundant on the northern prairie region, forming the "ISTorth- 

 ern Buffalo Grass" of the Canadian ranchman. Its seeds in the wetter 

 portions are very troublesome, penetrating the wool of sheep and cloth- 

 ing of men, and causing much annoyance. This grass, however, con- 

 stituted the winter food of the buffalo, and is now the delight of horses 

 in the winter season. It is usually classed with the "bunch" grasses. 

 There is no pa]-t of the dry prairie where it does not grow, from Por- 

 tage la Prairie westward to the Eocky Mountains. (^Macmn.') Pembina 

 Mountain, and from Winnipeg to Point du Chein, Man. (Bawson.') 

 Eed Eiver, Man., 1826. {Douglas.) 



(2741.) S. viridula, Trin. Act. Petrp. 39, (1836.) 

 S. spartea, Hook., Fl. II., 237, not Trin. 

 S. parviflora, Nutt. I., 58, not Desf. 



Very common around badger holes, and in coulees throughout the 

 prairie region and westward to the Pacific. Souris Plain, Man. 

 (J. M. Macoun.) White Mud Eiver, and Wood Mountain, Assiniboia. 

 (Dawson.) Bank of Souris Eiver, Man. (Burgess.) Abundant from 

 Winnipeg to the Eocky Mountains, and westward to the Columbia 

 Valley, at Donald ; common around Victoria, on Cedar Hill, and at Oak 

 Bay, Vancouver Island. (^Macoun.) Banks of the Saskatchewan. 

 (Hooher, Fl.) 



(2742) S. Columbiana, F. Sp. 



Closely related to the preceding, but much less in size, with a 

 smaller panicle and an awn scarcely an inch long ; glumes purplish, 

 acuminate to a slender point. Yale, B.C. ; Cedar Hill, four miles from 

 Victoria, Vancouver Island. (Macoun.)
