 row and dull leaves and the habitually darker spikes.

Taller than the species (13 to 20 in. high) and strict; 

 spikes large and compactly flowered, evenly cylindrical, longer 



peduncled. San Bernardino Mts., California, G. R. Vasej, Port- 

 land, Oregon, Henderson^ Howell. Very distinct in appearance.

Erect and mostly strict, not glaucous, i^ to 2^^ ft high; 

 leaves very lax and usually -exceeding the culm; spikes oblong, 

 green, more or less aggregated into a loose head, the lowest one 



or two subtended by a short and hyaline broad-based and pointed 

 or caudate bract; perigynium more spreading than in the species.

 that var. ccpJialaiitha represents in C. echinata. The two pla/its 

 are much alike, but this is readily distinguished from C. echinata^ 

 var. cephalantha, Bailey, by the ascending and canescens-like 

 small and marginless perigynia and the presence of scale-like bracts 

 beneath the lower spikes. The specimens from Maine and Ver- 

 mont, cited above, do not appear to have had the long and lax 

 leaves so characteristic of the species as found farther northward 

 and westward, and as figured by Boott. Future observation may 

 detect varietal dififerences here.
