. Van ELATIOR. 



Much taller, the leav^es very long and narrower; spikes long- 

 er (often 3 to 4 in.) and more slender, the lower much attenuated 

 below, the upper bearing conspicuous staminate portions ; bracts 

 long and narrow. Canon City, Colorado, Brandegee \ open

I 



specimens have been referred to this species by various writers, 

 but as fast, as complete and abundant specimens come to hand, 

 they are easily placed elsewhere. C. variabilis appears to be 

 abundantly distinct from all other species, but the van elatior 

 varies towards C, stricta^ var. Emoryi, Bailey, and C. aquatilis^ 

 Wahl- From the former, the above characterizations readily dis- 

 tinguish it. C, aqtiatilis is marked by its abundance of compar- 

 atively broad and long leaves and bracts, the solid spikes, very 

 broad perigynia, and minor characters ; its limits, particularly in 

 our West, are very imperfectly understood, and material is yet 

 scant.

Between C. stricta. Lam., and C. Nebraskensis, Dewey : Culm 

 slender but erect, sharply angled, mostly longer than the long- 

 pointed leaves (2 ft. high) ; staminate spike ope (or a rudimen- 

 tary one sometimes borne at its base), short (^ to I inch long), 

 short- peduncled ; pistillate spikes two to four, short (an inch or 

 less long, or the lowest sometimes longer and somewhat attenu- 

 ated below), closely sessile or the lowest one very short- peduncled, 

 cylindrical and closely flowered, the lowest usually subtended by 

 a leafy, slender bract two or three inches long the base of which 

 is normally somewhat hyaline and dilated, the other spikes 



C.angustata, W. Boott, Bot. Cal. ii. 242 (v. s, Hb. Gray.) appears to be a 

 narrow-spiked form of C. Ilaliii, Bailey,
