C. Janicsii, Torn Mongr. 398 (1836). 



Distinguished from the species chiefly by its longer and 

 sharper scales and more ascending pergynia.

C, crmita^ van, Sartw. Exsicc. No. 78 (1848), v. s. 

 Much smaller than the type (2 ft. or less high), the leaves half 



narrower; spikes small and short (i ;^ in. or less long); scale shorter 

 and smoother. Penn Yan. N. Y., Sartwcll ; Mt Desert, Me.,

"^ C. Broiigniartii, Bailey, Proc. Amen Acad. Arts and Sci. 



xxii. 137 (1886). 



The Pacific slope representative of C. vidpinoidea, Michx. : 

 Spikes looser-flowered than in that species, the perigynium much 

 larger and more spreading, somewhat stipitate, nerveless, or bear- 

 ing indistinct short nerves on the inner face, striated with brown 

 nerves on the back, the bracts wanting except the one or two 

 lower ones, which are setaceous and somewhat prolonged (/^ to 



i^ in. long), Oregon and California. I have examined the 

 original of C. Brongniartii^ Kunth (v. s. Hb. Rerol.) and find that 

 it is distinguished from the North American plant by several 

 characters, particularly by the much broader perigynium wliich 

 is prominently nerved inside. In fact, C, Brongniartii is closely 

 alllied to C. Muhlcnbergii^ Schk, Other plants, variously named, 

 from various parts of South America, approach more nearly our 

 plant, but it is impossible definitely to refer our species to any 

 South American species ; and I am confident that future obser- 

 vation will discover other permanent characters of separation, 

 uiasmuch as such has been the case in nearly every instance in 

 which Carices of the two countries, which w^ere supposed to be 

 identical, have been carefully studied.

Perigynium very strongly many-nerved or ribbed on the outer 

 face, and usually bearing three or four nerves on the inner face*
