Muhlenberg remarks tbe stigmas are two or three. I have 
observed two only apparent occasionally, but in each case the 
achenium was triquetrous, and the base of a third stigma visible. 
Tuckerman places this species among the Montanas, and Carey 
associates it with O. PLalseyana. I think its immediate affinity is 
with C. sccibrata and G. amplifolia. I have never seen any speci¬ 
mens so far south as Georgia. Elliott gives no particular locality, 
but quotes Pursh for its growing in wet meadows. His specimen 
was frorq Mr. Collins, and probably from Pennsylvania. Carey de¬ 
scribes it as growing in sandy soil, and I have very fine specimens 
from Tuckerman from “pine plains” at Schenectady, New York.

The American plant is paler and generally more gracile than the 
European one, especially than the remarkable specimens from 
Mennecy, near Paris, which I have from M. Gay, and from Herb. 
Maire, under the name of O. filiformis, and which in size certainly 
approach O. evoluta. All these specimens have the lower female 
spike conspicuously vaginate. Cosson and Germain (El. des En¬ 
virons de Paris, p. 60(3) quote Mennecy as the habitat of C. evoluta, 
which they regard as a var. (3 of O. filiformis, but they remark 
“bractees non-engainantes, meme l’inferieure.” 
The specimens of G. filiformis, figured Tab. CXXXII., are from 
Rhode Island. It extends (as far as I am informed) from Arctic 
America to Ohio.
