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 f oliosis ; 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
