summit, about 3 mm long, the awn about 5 mm long; second floret 
smaller than the first but not much reduced, glabrous, the awn about 
3 mm long; third floret about 2 mm long, truncate, mucronate, some- 
times a rudimentary fourth floret present (fig. 79). 
Cultivated in the warmer parts of America for forage and soon 
escaping into fields and waste places. The West Indian specimens 
appear to be all cultivated, but the species is likely to be found natur- 
alized. Rhodes grass gives promise of value in the drier parts of the 
West Indies.

Weedy branching decumbent-ascending annual; sheaths broad. 
compressed; blades thin, flat or folded, scaberulous or sparsely pilose; 
spikes slender, somewhat flexuous; second glume narrow, awn-pointed, 
2 mm long; lemma narrow, 2.5 mm long, the awn 5 to 10 mm long; 
rudiment narrow, scarcely 1 mm long, diverging a little from the fer- 
tile lemma and not as long as this, the awn as much as 5 mm long 
(fig. 80). 
Grassy banks, pastures, and waste places, Mexico and the West 
Indies to Paraguay. A common weed, to be found on probably all 
the West Indian islands.
