§ 3. ECHINÓCHLOA. Spikelets imbricated-spiked on the branches of the simple or compound raceme or panicle, usually rough with appressed stiff hairs; lower palet of the sterile flower awl-pointed or awned.
P. Crus-gálli, L. (Barnyard-Grass.) Root annual; culms stout, branching from the base (1–4° high); leaves lanceolate (½´ wide or more), rough-margined, otherwise with the sheaths smooth; spikes alternate (1–3´ long), crowded in a dense panicle; glumes ovate, abruptly pointed; glume of the neutral flower bearing a rough awn of variable length.—Varies greatly; sometimes awnless or nearly so; sometimes long-awned, especially in the var. híspidum, a very large and coarse form with the sheaths of the leaves very bristly.—Moist, chiefly manured soil; the variety in ditches, especially of brackish water; possibly indigenous. Aug.–Oct. (Nat. from Eu.)
6. SETÀRIA, Beauv. Bristly Foxtail Grass. ([Pl. 13])
Spikelets altogether as in Panicum proper, and awnless, but with the short peduncles bearing below the joint of the spikelet solitary or clustered bristles resembling awns (but not forming an involucre). Inflorescence a dense spiked panicle, or apparently a cylindrical spike.—Annuals, in cultivated or manured grounds, with linear or lanceolate flat leaves. (Name from seta, a bristle.)
[*] Bristles single or in pairs, roughened or barbed downward.
S. verticillàta, Beauv. Spike cylindrical (2–3´ long, pale green), composed of apparently whorled short clusters; bristles short, adhesive.—Near dwellings. (Adv. from Eu.)
[*][*] Bristles in clusters, roughened or barbed upward.
S. glaùca, Beauv. (Foxtail. Pigeon-Grass.) ([Pl. 13], fig. 1, 2.) Spike cylindrical, dense, tawny yellow (2–4´ long); bristles 6–11 in a cluster, much longer than the spikelets; perfect flower transversely wrinkled.—Very common, in stubble, etc. (Adv. from Eu.)
S. víridis, Beauv. (Green Foxtail. Bottle-Grass.) Spike nearly cylindrical, more or less compound, green; bristles few, longer than the spikelets; flower striate lengthwise and dotted.—Cultivated grounds. (Adv. from Eu.)
S. Itálica, Kunth. Spike compound, interrupted at base, thick, nodding (6–9´ long), yellowish or purplish; bristles 2 or 3 in a cluster, either much longer or else shorter than the spikelets.—Cultivated under the name of Millet, or Hungarian or Bengal Grass; rarely spontaneous. (Adv. from Eu.)
