Every species inhabiting such a wide area as S. longifolia and 

 growing under so many different ecological conditions will naturally 

 show a great degree of variability. Besides this there are quasi 

 intermediate forms with S. exigua in all the regions where both 

 species meet, and it is difficult to decide whether the northwestern 

 forms of what I call var. pedicellata really belong to S. longifolia 

 or to S. exigua, as Ball seems to believe according to his determina- 

 tions in different herbaria. The synonymy of var. pedicellata may 

 be given as follows:

" The specimen (preserved in N.) has been collected by James either in eastern 

 Wyoming or eastern Colorado, and seems to belong to this variety.
