Gen. Char. Panicle spiked, contracted. Spikelets (fig 1.) 2- 
or many-flowered, resting upon pectinated braeteas or involucrums 
(fig. 2.). Calyx (fig. 3 ) of 2 spear-shaped, nearly equal, mem- 
branous, concave, single-ribbed, keeled, taper-pointed, awned 
glumes, containing 2 or 3 perfect florets, the first sessile, the rest 
stalked, with an occasional rudiment of more. Corolla (fig. 4.) of 
2 unequal spear-shaped palece; the outermost concave, keeled, 
more or less awned at the summit, the awn straight ; inner 2-ribbed, 
inflexed at the edges, cloven at the point, awnless. Scales (fig. 5.) 
spear-shaped, pointed. Filaments (see fig. 4, a.) 3, hair-like. 
Nnthers (see fig. 4, 6.) strap-shaped, cloven at each end. Germen 
(fig. 6.) elliptical. Styles (fig. 6.) very short, distinct. Stigmas 
(see fig. 6.) long, cylindrical, feathery. Seed loose, invested with 
the unchanged palece, elliptic-oblong, with a furrow along the 
upper side. 
The contracted, spike-like panicle; the 2- or many-flowered 
spikelets, with pectinated involucrums ; the calyx of 2, equal, 
awned glumes ; and the corolla of 2 spear-shaped, keeled palece, 
the lower being awned or mucronate ; will distinguish this from 
other genera in the same class and order.
