E^'GLISH BOTANY. 
GENUS XVIL~p OLYPOGON. Desf. 
Spikelets shortly stalked, arranged in a narrow compact cylindrical 
or lobed often spikelike panicle with short lateral branches which are 
spreading only during the time of flowering, laterally compressed, 
open during flowering, each containing a single perfect floret without 
the rudiment of a second. Glumes 2, nearly equal, longer than the 
floret, bluntly keeled, notched at the apex, with a long awn proceeding 
from the bottom of the notch, scarious. Pales 2, unequal, membranous, 
the lower one not bearded at the base, entire or denticulate, with a 
short awn from the back immediately below the apex, or awnless; 
upper pale smaller, with 2 keels. Lodicules 2, glabrous. Stamens 3. 
Stigmas 2, subsessile, plumose, protruded at the sides of the florets 
between the basal margins of the pales. Caryops glabrous, free, ovoid, 
not compressed, with a shallow furrow on the inner face. 
The derivation of the name of this genus appears to bo from iroXvc, mucb, and 
Twywc, a beard, from the long awns of the florets.

Annual. Panicle very dense, oblong, witli approximate spreading 
])ranches when in flower, but closed, cylindrical, slightly lobed, and 
spikelike before and after flowering. Pedicels articulated above the 
base, the upper portion thickened, as long as broad (the breadth 
being measured at the apex), much shorter than the lower portion. 
Glumes obtuse, notched at the apex, where there are 2 subobtuse 
lobes about as long as broad and about one-eighth the lengtli of the 
rest of the glume, flnely scabrous-pubescent, ciliated with thick car- 
tilaginous hair^ on the keel and slender ones on the margins and 
apical Iobe^, with a scabrous dorsal awn s}>niiging from the bottom of 
the apical notch, and from two and a half to three thnes as long as the 
- >- ■ • truncnto and denticulate at the apex, with a
