Like Carex straminea Willd. in the eastern status, Carex 

 /estiva Dewey has had a great nuinl er <>' va.ying forms referred 

 to it. The present species is proposed to cover a plant which 

 differs from Carex /estiva in its narrow and short perigynium, 

 which is lanceolate and .| mm. or less long as compared with the 

 ovate perigynium of C. festiva, which is usually about 4.5 mm. 

 long. The spikes also average somewhat smaller than in C. 

 festiva, and are not at all separated. As the scales are but little 

 narrower than the perigynia the spikes present a brownish ap- 

 pearance, while in C. /estiva the scales being much narrower 

 than the perigynia the spikes are much greener in appearance.

No. 9272, collected August 4th, at Mclntyre's ranch near 

 Fort Halleck, in meadows, elevation 5^03 feet. This is a very 

 widely distributed species in the cooler parts of the northern 

 hemisphere. The larger American specimens have of late years 

 been referred to Carex Utriciilata Boott, but the characters on 

 which that species is erected are so trivial and variable that I d > 

 not believe it is worth recognizing even as a variety. 



The following species were collected in California:
