This isa distinct, beautiful, and finely characterized species, 
and is very appropriately named by Dr. Torrey. ad nam- 
ed it C. Sprengelii, but the other name must have the prefe- 
rence, as it was first published.

Our plant seems to be larger and to bear more fruit than the 
pecimens observed by Muh. in Pennsylvania. It is a very 
distinct and beautiful species. Though it belongs to a very 
natural division of the species of this genus, it is not closely 
allied to ary of them except the following species.

This species has rarely, if ever, been found in N, England. 
My specimens are from Pennsylvania, where it grows in dry 
woods, and flowers in June, according to Muh. It is closely 
related to C. polytrichoides, but differs from it in its fruit and 
scale, as well a8 in its place of growth. It is notso slender a 
plant, and its leaves are considerably wider and also more flat
