 rather closely 8-25-flowered, the upper two contiguous to 

 staminate spike and sessile or nearly so, the lower distant 

 and stalked; perigynia obovoid, ascending, ii"-i4" long, 

 more than 4" thick, narrowed at base, strongly nerved, 

 contracted into a short stout outwardly bent entire beak ; 

 scales ovate with broad white scarious margins usually
