Gen. Char. Panicle in a dense, cylindrical spike. Involu- 
c rum of many bristles surrounding 2 spikelets. Calyx (fig. 2.) im- 
perfectly 2-flowered, of 2 unequal glumes (valves), the lower the 
smallest. Corolla of fertile or perfect floret , (see f. 4.) of 2 equal, 
cartilaginous palece (valves) ; that of the neuter or imperfect one 
(see fig. 4.) of 1 or 2 palece or valves; the upper smaller and 
membranous, often wanting. Filaments (see fig. 4.) 3, hair-like, 
as long as the corolla. Anthers short, cloven at each end. Germen 
(see fig. 5.) egg-shaped. Styles (see fig. 5.) distinct, awl-shaped, 
as long as the stamens. Stigmas feathery, tufted, short. Seed 
(fig. 7.) egg-shaped, flatted on one side, coated with the ribbed 
hardened corolla (see fig. 6). 
The dense, cylindrical, spike-like panicle ; the bristly involu- 
c rum, including 2 or 3 flowers; and the calyx of 2 very unequal 
glumes, containing 2 florets, one of which is destitute of stamens 
and pistils ; will distinguish this from other genera in the same 
class and order. 
The bristly involucrum (fig. 2.) will distinguish it from Panicum. 
T wo species British. 
SETA'RIA VERTICILLA'TA, Whorled Bristle-grass. Rough 
Bristle-grass. 
Spec. Char. Panicle spiked, cylindrical, lobed below, branches 
whorled; bristles of the involucrum rough with reversed teeth. 
Paleae of the perfect floret slightly uneven.

* From seta, a bristle ; from the bristly involucrum. The true Millets be- 
long to this genus, which is the same with that of Pennisetum of Dr. R. Brown.
