Other English names: Poison Darnel, Bearded Darnel, White Darnel, Ivray, Poison Rye-grass, Annual Ray-grass. Introduced. Annual. Propagates by seeds. Time of bloom: Late June to July. Seed-time: July to August. Range: Locally in most of the United States as far south as Georgia; abun- dant on the Pacific Coast; occasional in Canada from New Brunswick to Manitoba; very troublesome in Red River Valley. Habitat: Grain fields and waste places. Darnel is now said to be poisonous only when diseased, its toxic properties being due to a fungus which has recently been discovered in the tissues under the seed coats. It is reputed to be most dangerous in wet seasons or when grown on wet soil. When ground with wheat, bread made from the flour is likely to cause "eruptions, trembling, and con- fusion of sight in man and flesh-eat- ing animals"; and if the seeds are malted with barley, the ale or beei "causes intoxication very suddenly"; but the plant is said not to be harmful in any way to grazing animals, and makes.
