Kachilla straight, glabrous. Glumes numerous, imbricated, angustato- 

 oblong, navicular, aristato-acuminate, entire, scarious, pale-ferruginous, 

 2- nearly 3mm. long; carina sub-3-nerved, viridescent. Stamen 1, lower 

 than the style and nearly equal to the glume in height ; filament filiform, 

 glabrous ; anther small, linear, -| mm, long. Style manifest, overtoping 

 the glume, rather stout, dilated at the base, deeply 3-fid into 3 branches, 

 persistent ; branches long, aristiform, patent, arcuate, ferruginose, papillose- 

 hairy, longer than the main portion. Caryopsis oblong-cylindrical, 

 straight, pale, smooth but delicately trabeculate under microscope, 1 mm. 

 long. •

This species has the general habit of Fimhristylis autumnalis Roem. 

 €t Schult., but is very distinct from it. The spikelets are remarkable by 

 the comose-squarrose deep-ferruginous style- branches. It seems to be 

 closely allied to F. Stauntoni Debeaux et Franch. of China.

Annual, glabrous. Roots fibrous, pale brownish. Stems numerous, 

 CEespitose, unequal in length, 1^-20 cm. long, slender, compressed, diffuse 

 or erect- patent or sometimes erect. Leaves basal, 1-2 to each stem, 

 shorter or much so than the stem, capillaceo-setaceous, with a membrana- 

 ceous sheath at the base. Cyme simply umbellate or sometimes subcom- 

 pound-umbellate, i-4 cm. across, rarely in depauperated monostachyous ; 

 radii 1 to 14, unequal in length, capillary, erect-patent or divaricately 

 spreading, monocephalous, the longest one about 2i cm. ; involucral bracts 

 few to several, capillary, shorter or longer than the cyme. Spicute ovoid- 

 globose to ovoid-oblong, 2^-6 mm. long, 2-3 mm. across, viridescent, densely 

 imbricated with setose glumes, the interior spicula sessile. Glume oblong, 

 fiubcarinato-convex, thinly membranaceous, pale-hyaline, 1^ mm. in whole 

 length, with a very delicate nerve near on each side of the midrib ; 

 midrib green, long-produced into a straight and erect setose tail which is
