Stem about two feet high, acutely triquetrous, concave on the sides so as 
to appear slightly winged, finely serrulate along the margins. Leaves long- 
er than the stem, the lower ones sheathing, channelled, nerved, very gla- 
brous, not even scabrous on the edges. Male spikes with us generally soli- 
tary, slender, pendulous, the scales lanceolate, mucronate. Female spikes 
generally three, not very distant, pendulous, on short peduncles merely en- 
veloped, not inclosed, each terminated by a number of male florets; scales 
ovate, with a long subulate point. Corolla ovate, compressed, terminating 
in a simple point, shorter than the scale. Stigmas two. 
Grows in river swamps. 
Flowers April — May.

scabrous along the margin, the lower sheathing the base of the stem, the 
upper sessile. Sterile spikes one to three, cylindrical; the fertile about three, 
the upper sessile, the lowest on a short peduncle, and the summit of each 
for nearly one third of its length frequently occcupied with sterile florets.
