On account of its immaturity, little dependence can be 
placed on the single specimen upon which C Bigelowii was 
originally established. It was collected many years since by 
Dr. Bigelovv upon the same mountain, and seems to be a 
more slender form of the same plant.

Hab. Arctic America, Dr. Richardson ! — We have seen 
no original specimen of this species. The plant which Prof. 
Dewey refers to C. mutica has 3 stigmas in one flower at least, 
and appears to us to be C. limosa var. rarijiora.
