North American Cijperacece. 407 



Hab. Sitcha. Bongard ! ; Columbia river, Dr. Scolder! — 

 Having had the good fortune to receive an original specimen 

 of C Mertciisii, we are enabled to satisfy ourselves of its 

 identity with C. Columbiana. We find, indeed, that although 

 C. Mcrtensii is described as distigmatic, at least half the fer- 

 tile flowers in our specimen are furnished with 3 stigmas.
