Muh. Pursh. Eaton. 
Schk. tab. Xxx. fig. 175. 
Spiculis pluribus alternis oblongis erectis, suprema infer- 
ne mascula, ceteris femineis vel androgynis inferne mascu- 
lis; fructibus erectis lanceolatis acuminatis scabris nervosis 
bifidis, squama ovato-lanceolata duplo longioribus. 
Culm 10—18 inches high, leafy towards the base ; leaves 
linear, scabrous on the edges, shorter than the culm; bract 
scabrous, lanceolate, awned, supporting the lowest spikelet, 
and about its length; stigmas two; spikelets all pistillate, 
all staminate, the highest staminate below, and the others 
pistillate, androgynous above and below, and staminate in 
the middle, or the middle ones staminate below, having a 
single staminate plant at their base. 
Though the common appearance of this species, is 
shown on the fig. of Schk., the variations of the spikes form 
some obstacle to the ready knowledge of it. Muh. remark- 
ed several of these variations. As the androgynous spikes 
are staminate below, it should be removed, as the descrip- 
tion of Muh. requires, from the section in which it is placed 
by Ph. and Eaton, to the next following section. It occurs 
in small bogs, or cespitose clusters, and is readily recogni- 
zed after it is once found. Pursh says it grows “in dry 
fields and woods;” but, according to Muh., it inhabits 
marshes or wet situations, in which alone have I found it, 
or known of its being found, in the Northern States. Flow- 
ers early in May—common.
