Description
|
Spikelets in pairs at the nodes of a readily disarticulating rachis, the rachis segments and pedicels narrow at the base, gradually widened and thickened to the summit, densely ciliate-villous on the margins; sessile spikelet laterally compressed, the first glume deeply sulcate, 2-keeled, awnless, the second glume with a slender somewhat divergent awn; fertile lemma shorter than the glumes, 3-nerved, awned from between 2 small teeth, the awn once-geniculate, much longer and stouter than those of the glumes; pedicellate spikelet prominent; first glume broad, flat, many-nerved, rather abruptly acute or acuminate, bearing a slender awn from between the slender teeth of the bifid apex; second glume much shorter and nar- rower, acuminate.

Erect, branching annuals with solitary racemes somewhat aggregate on the branches from the upper nodes, forming a narrow but rather loose compound inflorescence.
