 narrow, closely sessile and agglomerate at the top of the culm 

 (or rarely one remote or radical), perigynium very small and 

 short-beaked (half or less the size of the foregoing varieties), 

 straight or nearly so, yellow or golden in color when mature, the 

 bracts long and mostly erect and involucre-like from the ag-

 Differs from the last, among other characters, by its greater

height (often a foot or more high), larger and longer spikes, 

 and much longer and usually stricter bracts, and usually the much 

 duller color of the spikes. Newfoundland to Pennsylvania and 

 westward to Montana, Williams and S. Utah, Parry. Usually 

 •appears distinct from the species, but its relationship to van 

 cyperoides is very close and that variety clearly belongs to C. Jlava.
