ear-oblong (£' long), almost sessile, horizontal, numerous and rather 
remote, forming a strict raceme (8'- 12' long); rachis tipped with a 
slender naked point; lower palea smooth, 3-pointed, that of the abor¬

long and filiform rays (rachis) of a crowded naked raceme. 
Glumes lance-awl-shaped, keeled, almost equal, rather longer 
than the somewhat equal membranaceous pale* ; of which the 
lower is cylindrical-involute, with the midrib produced from just 
below the 2-cleft apex into a straight and slender bristle-like 
awn ! the upper with the abortive flower at its base. Stamens 3. 
Stigmas pencil-form, purple. — Leaves short and flat. (Name 
composed of yvpvos, naked , and nuyvv, a beard , alluding to the 
reduction of the abortive flower to a bare awn.) 
1. G. racemosus, Beauv. Culms clustered from a short 
rootstock (1° high), wiry, leafy; leaves oblong-lanceolate, pale, thick- 
ish (2'-3' long); awn of the abortive flower shorter than its stalk, 
not exceeding the pointed glumes. (Anthopogon lepturoides, JS’utt.)

flowering culms. Glumes keeled, pointless, rather unequal. Pa¬ 
le* pointless and awnless, the lower larger, boat-shaped. Sta¬
