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

Very abundant on the northern prairie region, forming the "Northern Buffalo Grass" of the Canadian ranchman. Its seeds in the wetter portions are very troublesome, penetrating the wool of sheep and clothing of men, and causing much annoyance. This grass, however, constituted 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 part of the dry prairie where it does not grow, from Portage la Prairie westward to the Rocky Mountains. (Macoun.) Pembina Mountain, and from Winnipeg to Point du Chein, Man. (Dawson.')
