This comes near some of the specimens referred to S, longifoliumy 

 Huber, and it is very simihir to Hassler's 4833^ ivhich Chodat has 

 named S. higlandnlosiim , var. longifolia^ forma longissima in Bull. 

 Herb. Boiss. ser. 2, vol, v. p. 676, but that has broader, less rigid, less 

 distinctly toothed leaves on longer petioles, with a more distinct 

 venation. The capsules, too, of S, longifolium are less crowded and 

 distinctly stalked. — W. Bottixg Hemsley.
