turn asquante ; setis retrorsum hispidis, nucem plus duplo 
longioribus. 
Culm triangular, 3 — 4 feet high. Leaves linear, smooth, somewhat sca- 
brous on the margin and keel. Panicles numerous, approximate, so 
as to appear like a single elongated, compound panicle ; often two or 
more from the same sheath. Peduncles compressed, scabrous, nearly 
erect, much longer than the sheaths ; the lower ones longest. Bracts 
filiform-setaceous, with scabrous margins, equal to the panicles. 
Flowers in small fascicles, crowded on the ultimate divisions of the 
panicles. Spikelets ovate-lanceolate, Glumes lanceolate, rather ob- 
tuse, with a short mucro. Bristles 6, conspicuously retrorsely hispid, 
more than twice the length of the nut. Stamens 3. Style slightly 
bifid. Nut smooth, obovate, lenticular, broad at the summit, sub- 
attenuate at the base. Tubercle subulate, compressed, as long as the 
nut.

22. Rhynchospora oligantha. 
R. culrno subaphyllo, filiformi ; spiculis paucissimis, ovato- 
oblongis ; setis sursum hispidis, infra medium plumosis, nu- 
cem oblongiuscule obovatam (minutissime exasperatam,) 
paulo superante ; tuberculo brevissimo, conico. 
Culm filiform, 6 — 12 inches high, nearly leafless. Spikelets 1 — i, 
two to four lines long, solitary or in twos or threes on a slender, sca- 
brous peduncle, surrounded by a single filiform bract, which appears 
like a continuation of the culm : sometimes there is a single, remote, 
long-pedunculate, lateral spikelet. Glumes broad-ovate, acute. 
Florets raised on a naked, articulated stipe, about a line in length. 
Bristles 6, as long as the nut and tubercle, hispid upward, plumose 
below the middle. Stamens 3. Stjjle bifid. Nut to the naked eye 
nearly smooth, (minutely roughened under a powerful lens,) obovate- 
oblong, subterete, with a very short acumination supporting a conic 
tubercle, scarcely i the length of the nut.
