obscure carinatis; nucibus obovoideis, triangularibus, laevibus 
vel obscurissime transverse lineatis ; stylo 3-fido. 
A densely caespitose, leafless, perennial plant 0.6 to 1 m high 
from stout rhizomes, the lower parts of the culms with 3 or 4 
rather loose, imbricate sheaths, the lower ones ovate to oblong- 
ovate, 1 to 2 cm long, the upper one up to 10 cm long, the mouth 
oblique, with a broad, brown, membranaceous margin. Culms 
prominently 3- or 4-angled, rather stiff. Inflorescence termi- 
nal, 2 to 4 cm long, open, umbellately decompound, subtended 
by one or two, lanceolate, acuminate, leaf -like, 1 cm long bracts. 
Spikelets numerous, not fascicled, usually one sessile median one 
and two lateral pedicelled ones on each ultimate branchlet, 2.5 
to 3.5 mm long, brown, ovoid, the pedicels scabrid; glumes 10 
or fewer, brown, ovate, acute or obtuse, obscurely keeled. 
Stamens 3. Nut obovoid, 3-angled, white, 0.8 to 1 mm long, 
smooth or very obscurely transversely lineate; style-arms 3.

Apparently a very characteristic species allied to Fimbristylis miliacea 
Vahl, F. quinquangularis Kunth, etc., but differing in its leafless stems, 
large rhizomes, smooth or nearly smooth nuts, and other characters. 
FIMBRISTYLIS PINETORUM sp. nov. § Trichelostylis. 
Erecta, glabra, culmis e rhizomate crasso, solitariis, gracilibus, 
20 ad 40 cm altis, basi foliosis ; foliis paucis, subsetaceis, usque ad 
13 cm longis ; inflorescentiis simpliciter umbellatis ; spiculis pau- 
cis, 3 ad 7, brunneis, oblongo-ovoideis, 6 ad 11 mm. longis ; nucibus 
obovoideis, verruculosis, albidis, 1 ad 1.2 mm longis, obscure 
triangularibus; stylo trifido. 
A solitary, erect, slender, perennial plant from stout, woody 
rhizomes, the rhizomes clothed with membranaceous, lanceolate, 
usually brownish scales or sheaths, usually about 1 cm long. 
Culms striate, 20 to 40 cm high, the base with several imbricate 
leafless sheaths, and at or near the base 2 to 4 leaf-bearing 
sheaths, the sheaths oblique, their margins membranaceous, the 
leaves linear or setaceous, involute when dry, 1 to 1.5 mm wide, 
4 to 13 cm long. Inflorescence usually a simple umbel, rarely 
compound, 2 to 3 cm long, the subtending bract lanceolate, acu- 
minate, usually less than 1 cm long. Spikelets oblong-ovoid, 
brown, many-flowered, 6 to 11 mm long, 3 to 7, one sessile, the 
others mostly slenderly pedicelled, the pedicels 1 to 2 cm long. 
Glumes ovate, concave, keeled, glabrous, acute to obtuse, often 
retuse, the margins thinner and paler. Stamens 3. Nut white, 
obovoid, 1 to 1.2 mm long, obscurely 3-angled, apex broadly
