80 EBPOBT OP THE STATE BOTANIST. 



Adirondack mountains. July. 



It forms small dense tufts, the short capillary stems often being 

 prostrate at maturity, the longer leaves parti}' concealing the fruit ; 

 or, they are suberect, and the spikes drooping; by which, and the 

 apparent absence of the sterile spikes, this delicate species may 

 be readily known. 



Var. Deanei Hailey. Stems 6'--12' high, mostly longer than 

 the leaves ; staminate spilce 2"--3" long, less than \" wide, often 

 oblique; pistillate spikes 4-8 flowered, '2"-3" apart, the lowest 

 conspicuously stalked, its bract leaf-like and longer than the culm ; 

 radical spikes few or numerous.
