(fig. 1.) single-flowered. Calyx (fig. 2.) of 2, equal or unequal, 
spear-shaped, concave, pointed, keeled, compressed glumes, longer 
than the paleae. Corolla (see fig. 3.) of 2, unequal, membranous, 
ribbed paleae, surrounded with hairs at the base ; the outer palea 
largest and awned. Filaments (see figs. 1 & 3.) 3, hair-like, about 
the length of the calyx. Anthers cloven at each end. Gcrmen 
(see fig. 4.) oval, or inversely egg-shaped. Styles (see fig. 4.) 2, 
short. Stigmas (see figs. 3 & 4.) feathery, closely tufted. Seed 
oblong, pointed at each end. 
The loose panicle; the single-flowered spikelets; the calyx of 
2 glumes, longer than the corolla; and the corolla of 2 unequal, 
membranous palea, surrounded with hairs at the base, with the 
outer palea awned ; will distinguish this from other genera in the 
same class and order.
