Nat. ord., Graminaceae.
Characters. - An erect or slightly decumbent annual grass, 1 to 2 feet high, leafy only in the lower part. Spike 6 inches to 1 foot long, the spikelets at a considerable distance from each other. It is closely allied to the Lolium perenne, but the root is always annual, the outer glume of the spikelets usually as long as the spikelet itself, the flowering glumes shorter and broader, and some of them at least have an awn longer than themselves.
The poisonous effects of the seeds of this plant have probably led to its introduction into the Homoeopathic Pharmacopoeias.
Parts employed. - The ripe spikelets.
Preparation. - Tincture.
