GENUS VIL—S E T A R I A. Pal. de Beauv. 
Spikelets subsessile, in small fascicles arranged on every side of the 
rachis of a dense cylindrical or slightly lobed spikelike panicle, dorsally 
plano-convex, closed during flowering, each surrounded at the base 
by an involucre of stiff bristles, and containing a single perfect floret 
with an imperfect male one beneath it. Glumes 2, very unequal, the 
lower one much smaller than the upper, the upper rather shorter than 
the pales, indistinctly ribbed, pointed but not awned, scarious. Pales 
2, equal, parchmentlike, indistinctly ribbed or transversely rugose, 
acute, but not awned, concave, but not keeled on the back, the lower 
floret with 1 or 2 pales, the lower of which or the only one is indistinctly 
ribbed and resembles the upper glume. Lodicules 2, fleshy. Stamens 
3 in the perfect flower, but usually only 1 or 2 in the male flower. 
Styles 2, terminal, elongate ; stigmas short, thick, hairy, protruded at 
the apex of the flower. Caryops glabrous, free, plano-convex, not 
furrowed. 
This genus of Grasses is so caUed from seta, a bristle or hair.

Panicle spikelike, oblong-cylindrical or fusiform-cylindrical, verj- 
dense, continuous, not lobed. Bristles of each spikelet 3 to 6, more 
than twice as long as the spikelet, rough with prickles pointing 
upwards, green, often tinged with purple. Upper glume as long as 
the fertile floret. Upper pale of the male floret half the length of the 
lower, which about equals the fertile floret. Pales of the fertile fluret 
equal, finely punctured, ])iit not transversely wrinkled. 
A weed ni cultivated fields, gtirdens, and waste ground. Rather 
rare, and a doubtful native. Surrey, Norfolk, Suffolk, and perhaps 
Middlesex, appear to he the only counties in which it has anv claim 
to be considered in<ligenous, alt'i.-.iigh it casually occurs in manv 
others. I liave gathered it in Kent and Essex, as well as in the 
counties mentioned above, and possess specimens from Tilouce^ter and 
Warwick.
