In this connection it may be remarked that var. stihloliacea, 

 Laest. of C. cancsccns, is a very different plant from C, canescens, 

 var. vulgaris, Bailey. (See Bot Gaz. xiii. 85, where remarks 

 were made concerning these plants). As compared with the var. 

 vtilgariSy var. stibloliacea has shorter and rounder perigynia, 

 more like those of the type of the species, — and which are silvery 

 in color and somewhat puncticulate.

The '' rough-ciliate mucro " of the pistillate scales is not 



pronounced.

C, atiisostachys, A fine species, allied, with the last, to C. 



viresccjis, Muhl C. monticola has more the port of C. vi- 



rescens, as the pistillate portion of the terminal spike is 



longer than in this species. C. anisostachys has toothed 



perigynia, while those of C, monticola are entire, and the 



scales in C, aiiisostachys are much more acute than in the 



other. The terminate spike is rarely all staminate.
