Avena

(classical name). G~ra-miners. Oars. A genus of annuals or perennials well known from the cultivated oat. Panicles wide open, and loosely flowered, bearing large 2-6-flowered spikelets. A long, twisted, geniculate awn present, except in the cultivated oat. Species, about 50. Widely spread in the temperate regions of the Old and New World. latua, Linn. WILD-OATS. S.um-oars. Resembles the cultivated out; can be distinguished by the larger spike lets and long, brown hairs on the flowering glume. Awn an inch in length. Eu.—A very troublesome weed in some parts. Not cult. stérilis, Linn. Asrsuvrso Oars. Much larger than the cultivated oat: spikelets large, in a drooping panicle; awn very long and genicnlate. Mediterranean region and E.— Occasionally cult. for the odd behavior of the "seeLls.” It is the twisting and untwisting of this awn, when exposed to moisture and dryness, that has given to the grass the name Animated Oats. The untwisting of the awn causes the spikelet to tumble about in various directions, suggestive of independent motion. The common oat is Avma saliva, Linn., native of the Old World. Pasture grasses sold as Avenas are A. elatior, which is an Arrhennntherum ; and A. Ilavucenc, which is a Trlsetum. P. B. Ksmnznv.
