MONOECIA TRIANDRIA.

1. Oligantha? 
S. culmo gracili, tri- 
quetro, glabro; foiiis 
angustis, nervosis, sca- 
briusculis; spicis 2 — 3 
subterminalibus sessi- 
libus, 1? laterali, rerao- 
ta, loisge pedunculata; 
nace nitidissima. E. 
Mich. 2. p. 167? 
Stem slender, trique- 
trous, glabrous; leaves 
narrow, nerved, slight- 
ly scabrous; spikes 2 
— 3 near the summit 
of the stem, sessile, one 
lateral remote, on a 
long peduncle; nut ve- 
ry smooth and polish- 
ed. 
Stem twelve to eighteen inches high, slender, triquetrous, nerved, a little 
scabrous along the margins and slightly pubescent near the summit. Leaves 
linear, nerved, acute, slightly scabrous on the upper surface, a little pubes- 
cent near the base and on the sheath, shorter than the stem. Flowers in 
small fascicles or spikes, two sometimes three, sessile near the summit, one 
on a long peduncle (two to three inches) near the middle of the stem, each 
containing one fertile and two to three? sterile florets at its base. Bracteal 
leaves resembling those of the stem, the two upper ones much longer than 
the spikes, the lower sheathing the base of the peduncle. Scales of the 
sterile florets ovate, acute, very slightly pubescent; of the fertile longer, 
very acute, glabrous. Seed one, white, very smooth, and polished. 
It appears to me probable that this species is the S. Oligantha of Michaux, 
for the upper spikes are distinct, which in S. Pauciflora are fasciculate. His 
silence respecting the seed must, however, leave this uncertain, unless his 
own herbarium can resolve the doubt. This, however, is not the S. Pauci- 
flora of Pursh, nor S. No. 4 , of Muhl. Gram. p. 268 , under which a refer- 
ence is made to S. Oligantha, Mich, as both of those plants have rugose seeds. 
Grows in wet pastures and pine barrens. St. John’s, Dr. Trescott. 
Flowers May. 
2. Gracilis. E. 
S. culmo filiformi, 
triquetro, foliisque gla- 
bris; spiculis paucis, 
paucifloris, fasciculatis, 
subterminalibus; glu- 
mis glabris; nuce laevi, 
nitido. E. 
Stem filiform, trique^ 
trous, and with the 
leaves glabrous; spikes 
few, few flowered, fas- 
ciculate, nearly termi- 
nal; glumes glabrous; 
nut smooth, polished.
