=Chloris incompleta, _Roth._=

This is a perennial grass. Stems are procumbent when growing in open
places, but erect if growing amidst bushes, often branched, ending in
long naked peduncles, varying in length from 1-1/2 to 4 feet. In some
cases prostrate stems produce roots at the nodes.

The _leaf-sheaths_ are long, glabrous, the mouth being generally hairy.
The _ligule_ consists of long hairs. _Nodes_ are glabrous.

The _leaf-blades_ are linear, flat, finely acuminate and narrowed into
very long points at the apex; glabrous or slightly hairy at the base and
contracted, 4 to 10 inches long and 1/6 to 1/4 inch broad.

The _inflorescence_ consists of two to five rarely six, very slender
spikes, 3 to 8 inches long, forming a terminal whorl. The rachis is fine
and scabrid.

_Spikelets_ are narrowly lanceolate, closely appressed and imbricate,
1/6 inch long excluding the awn and very variable. There are four
_glumes_ in the spikelet. The _first glume_ is very small
linear-lanceolate, acute, about 1/10 inch or less. The _second glume_ is
lanceolate, membranous, three times the length of the first glume,
2-toothed at the apex and the mid-nerve produced into a very short awn.
The _third glume_ is oblong-lanceolate as long as the second glume or
longer, 2-toothed at the apex, awned, the awn being about 3/8 inch long;
the callus is bearded at the base. The palea is as long as the glume,
2-toothed or not at
