MONOECIA TRIANDRIA. 
Plant about a foot high, very slender, and in my specimens entirely 
smooth. Leaves linear, very narrow, shorter than the stem. Bracteal leaf 
resembling those of the root, theee to four inches long. Spilces two or three, 
clustered together at the summit of the stem, each bearing one fertile floret. 
Scales ovate lanceolate, slightly mucronate, ferruginous, glabroi^. Nut 
m white, showing in some specimens slight longitudinal ribs.

Stem about two feet high, very acutely triquetrous, striate, scabrous, and 
a little hairy near the summit. Leaves about twelve inches long, three to 
four lines wide, somewhat scabrous, hairy along the angles, sheathing the 
stem at base. Flowers generally in one terminal and one lateral cluster 
each composed of three or four aggregated spikes, the lateral cluster usu- 
ally pendulous. Bracteal leaves much longer than the spikes, pendulous. 
Calyx of both florets three-valved, valves ovate, carinate, mucronate, some- 
what unequal, conspicuously fringed. F emale florets two or three in each 
spike. Style one. Stigmas three. Seed white, polished, showing some 
slight inequalities on its surface. 
This is the most common of our species. I have always doubted whether 
it is the S. Triglomerata of Michaux; but it agrees better with that than with 
any other of his species. It is not the S. Triglomerata of Pursh. 
Grows in dry soils.
