leaves having only one spine at the tip (f. integrifolia, Van Hoffen ?), 

 thus getting a certain resemblance to S. hronchialis, L. Another stunted 

 form the S. Chamissoi, Sternb. represents, as far as can be judged 

 from the figure (1. c, T. 10). The flowers were found after the middle 

 of June, and than its flowering time continued until the frost set in. 

 The flowers often remained frozen all through the whole winter, so as 

 to give the plant the appearance, in early spring, of having already 

 begun to flower; but when the blossoms thawed they soon faded.

This species is rather commonly distributed, but rarely abundant. 

 It is rather variable in size, hairiness, etc., and the inflorescence can be 

 either subcapitate or branched, very often there is a stronger branch 

 some way down on the stalk, below the rest of the inflorescence. Be- 

 sides the typical form, also occurs the variety:
