is species, in so far as it has been collected, has seemingly passed as C- 
jasciculatum Kellogg, Wats. Proc. Am. Acad. 17: 380. That is a very different 
thing, as may be seen by referring to the original description, or to Howells’s 
Fl. N. W. Am. 632. It is, moreover, of a quite different geographical range. I 
have great pleasure in naming this fine species for Miss Harriet Knight, whose 
sympathetic interest in all nature and whose intelligent activity in the educa- 
tional work of Wyoming is greatly appreciated.
