line above; the margin reflexed, and with straight pili on the edge 

 above. Flowering glume much smaller than I-II-III-glumes, 

 membranaceous, hyaline, about mm. long, oblong, 2-cleft 



with ovate or lanceolate subobtuse or acutish entirely ciliolatcd 

 lobes at the apex, scabcrulose in the back above, ciliolatcd on 

 the margin above, 3-nerved at the lower portion, the nerves con- 

 nate above and become into an awn, the lateral nerves arcuate ; 

 awn arising from the bottom of the sinus, long and very much 

 exserted (34-41 times as long as the spicule) beyond the spicule, 

 13-23 mm, long, setaceous, erect, sub-straight, twisted when 

 dried and geniculate in the midst, longitudinally slenderly 

 canaliculate, scabrous on margin and brunneous-brown in the 

 lower half, slightly flattened below and scabrous on both sides 

 and light brown in the upper half. Palea minute and smaller 

 than the flowering glume, lanceolate, 3-dentate with acute 

 teeth at the apex and the middle tooth largest, membrana- 

 ceous, hyaline, subentire but slightly pilosulous on margins, 

 very thinly pilosulous on the upper portion of the dorsal sur- 

 face, enerved. Lodicules 2, very minute, sub-flabellate, both 

 sometimes adherent with the inner edges, the front edge ob- 

 liquely truncate and with a few pili, pilose at the angles, whit- 

 ish or ferruginous, rather thick. Stamens 3 ; filament filiform, 

 longer than the anther, slightly broader at the base, about 

 3 mm, long; anther linear, straight, dark-brown, versatile and 

 inserted to the filament below the middle, 2i mm. long ; anther- 

 cells obtuse at the ends. Styles exserted upon the glumes, con- 

 nate into one at the base, capillaceo-filiform, thicker towards 

 the base, flexuous above, about 3 mm. long, whitish or ferrugi- 

 nous above ; stigmas long, plumose, dark-brown, longer than 

 the style, mm. long, pili fine and dense, erect-patulose or 



patent, linear-oblong in outline. Ovary minute, cylindrical- 

 oblong, smooth, ferruginous or yellowish-ferruginous, | mm. 

 long. Caryopsis cylindrical-oblong, obtuse and with the remams 

 of the basal portion of the old style at the apex, acute at
