staminate spike linear, 3"-9" long, borne on a stalk T-IO" in 

 length, light brown ; pistillate spikes 2-3, approximate, the upper 

 two sometimes contiguous and sessile, or the lower two stalked, 

 the lowest sometimes borne on an erect or spreading peduncle 

 6"-9" long, subdensely or loosely flowered, often interrupted and 

 tapering at base, j-'-l^' in length; bracts short setaceous, or the 

 lowest sometimes exceeding the spike ; perigynia elliptical, 

 nerved or nerveless, whitish green, mostly covered by the blackish- 

 purple elliptical scale. 



It may be distinguished from the related species by its small 

 size, blackish fertile spikes and by its alpine habit. 



Summits of the higher peaks of the Adirondack mountains, 

 especially Mt. Whiteface and Mt. Marcy. 



In the fifth edition of Gray's ilanual, Carey describes a very 

 different plant under the above name.
