Black Oat Grass
Black Oat Grass (Stipa avenacea) is found in dry, sandy woods and has no agricultural value. It grows one to two feet, and has an open panicle. The leaves are almost bristle like. The palea is blackish and nearly as long as the glumes. It is a prairie grass common to Michigan, Illinois, Wisconsin, and the south. The upper palea and its bent and twisted awn is seen here.
