nearly equal, spear-shaped, keeled, compressed, pointed palea , the 
lower slightly awned under the apex, with a tuft of hairs at the 
base. Nectary (see fig. 4.) of 2, minute scales, longer than the 
germen. Filaments (see figs. 1 & 3.) 3, hair-like, about the length 
of the calyx. Anthers cloven at each end. Germen (see fig. 4.)

The close spike-like panicle ; the single-flowered spikelets ; the 
calyx of 2, nearly equal, keeled glumes , longer than the corolla ; 
and the corolla of 2 palece, the lower of which is awned under the
