^C. LURIDA, Wahl {C. tentaadata, MuhL), var. FLACCIDA. 



Low, scarcely exceeding a foot or fifteen inches high ; spikes 

 two to four, all sessile and approximated at the top of the culm, 

 small and straight (an inch or less long), dull brown or reddish- 

 brown, loosely flowered ; perigynium very thin and membrana- 

 ceous, the body mostly larger than in the species and more grad- 

 ually contracted into the beak. Central N. York, Dudley, to
