 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, 

 is" long, f" wide, several-nerved on both faces, 

 spongy and round-tapering at base, abruptly narrowed 

 into the smooth beak i~k length of body, its teeth

 ovoid head ii' or less long; perigynia subulate, 

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

 3" long, scarcely 4" 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.
