staminate at top, the lower short-peduncled, with leafy bracts ; lower bract 
exceeding the culm and with a short sheath ; stigmas 2 ; perigynium spread- 
ing, obovate or elliptical, slightly tapering at base, lenticular, apiculate, 
bilobed or emarginate, the orifice toothed, nerved, a little shorter than the 
acute or lanceolate dark-rusty scale, which has a whitish niidril). Root 
stjoloniferous ; culm 16-24' high ; leaves leathery, broad, erect, nearly equal-

to separate this from C. Jamesii. Fort Pierre, Nebraska, (ITay(h3n ;) CMear
