MONOECIA TRIANBRIA, 
triquetrous, nearly white, terminating in a very short, two-cleft summit. 
Lower bractea longer than the spike, the upper ones shorter. 
Grows in swamps and bogs in the upper districts of Carolina. Dr. 
Schweinitz.

Spikes 3 androgy- 
nous, 2 female, erect, 
cylindrical, peduncu- 
late, distant; fruit o- 
vate, acuminate, two- 
pointed, hairy, longer 
than the ovate lanceo- 
late, awned scale. 
Pursh, 1. p. 40. Nutt. 2. p. 204. 
Stem two to three feet high, acutely triquetrous, serrulate along the mar- 
gins. Leaves four to seven lines wide, rather longer than the stem, chan- 
nelled, very acute, scabrous on the upper surface, the margins and midrib 
serrulate, sheathing at base. Flowers in distinct spikes, the sterile superior, 
one to five, alternate, terete, sessile, one to two inches long; fertile spikes 
two to three, remote, nearly sessile, erect, cylindrical, the fruit expanding. 
Of the sterile florets the bracteal leaf is setaceous or subulate, the lower lon- 
ger than the spike, the scale lanceolate, rather obtuse, the midrib rufous. 
Stamens three. Of the fertile spike the bracteal leaves resemble the root 
leaves, are very long, and have little or no sheath. Scale lanceolate, slightly 
mucronate. Corolla ovate, inflated, nerved, acuminate, pubescent, a little 
longer than the scale. Stigmas three. Seed obtusely triquetrous. 
Our plant is larger than the specimens sent me from Pennsylvania by Dr. 
Muhlenberg, and the fruit less hairy. Does it belong to this section? 
Grows in deep swamps; to me rare; found in fresh marshes along the 
Ogeechee river. 
Flowers in April.
