 spreading perigynia, subglobose or short-oblong, more 

 or less separate, 2"~$\" long, 2"-$" wide, the terminal 

 gynaecandrous, or sometimes entirely staminate, 

 much longer and long-clavate at base; perigynia 

 green, plano-convex, ovoid-oval, broadest near middle, 

 ii" long, I" wide, several-nerved on both faces, 

 spongy and round-tapering at base, abruptly narrowed 

 into the smooth beak i-J length of body, its teeth 

 short, erect; scales ovate, hyaline, shorter than peri- 

 gynia; achene in upper part of perigynium.

 spikes 4-15, greenish or straw-colored, oblong, 

 densely many-flowered, the larger 4"-6" long, 2i - 

 3z" wide, aggregated and confluent into an oblong or 

 ovoid head ii' or less long; perigynia subulate, 

 substipitate, the margin at base nearly obsolete, 2i"- 

 3" long, scarcely \" wide at the base, distended over 

 achene, tapering into a subulate rough 2-toothed beak 

 2-3 times as long as the few-nerved body; scales 

 linear-lanceolate, long-acuminate, hyaline, much 

 shorter and rather narrower than the perigynia. 



In meadows and thickets, Ontario and central New

 io"-is" long and»2l"-6" thick; perigynia erect- 

 ascending, subulate, the margin at base nearly 

 obsolete, rounded at base, 2"-o.\" long, ¥'-¥' wide 

 at base, distended over achene, tapering into a 

 narrow rough 2-toothed beak shorter than the 

 lightly nerved body; scales dark brown with
