to American Botany. I believe its characters to be sufficiently distinct 

 to warrant its separation from that species. Specimens were collected 

 near Maclcod's Lake in Northern British Columbia which completely 

 accord with the description of this species and are altogether unlike 

 any form of S. borealis we possess. The character, " leaves ovate- 

 lanceolate, connate, the margin minutely ciliate with white hairs, much 

 shorter than the internodes," separates it from that species.

(298.) S. crassifolia, Ehrh. Gray, Manual, 93. 

 & borealis, var. /?, Hook. Fl. I., 95. 



St. Paul's Island. Gulf of St. Lawrence. (McKay.) Frequent in low 

 damp spots in the prairie region. Specimens from the Cypress Hills 

 and Hand Hills are like the eastern forms. (Macoun.) Sitka. (Mertens.) 



(299.) S. gracilis, Richards. Hook. Fl. L, 97. 



This species is doubtfully referred to S. uiiginosa by Watson, but is in 

 my opinion quite distinct. The abundant gemma? in the axils of the 

 leaves and its peculiarly lax habit amply distinguish it from S. uiiginosa. 

 Abundant on the banks of Methy River, near Portage La Loche, Lat. 

 57. (Macoun.) York Factory, Hudson's Bay. (R.Bell.~) About Slave 

 Lake, and between Cumberland House and Hudson's Bay. (Rirhar-lzon.') 



(300.) S. longipes, Goldie. Long-stalked Stichwort. 

 S. glauca, Meyer. PL Lab., 93. 



Dry gravelly river banks and margins of lakes, also sandy woods in 

 the north. Very abundant in many places from Nova Scotia to the 

 Pacific. In its various forms it is found on the mountains, on the 

 prairie and in the forest, and extends northward to the shores and 

 islands of the Arctic Sea. The eastern form is tall, rigid and generally 

 glaucous. (Macoun.) Greenland. (Hook. Arct. PL)
