The Floating Foxtail (Alopecurus geniculatus) has a stem ascending, bent, and forming knees at the lower joints. It has linear anthers and its upper leaf is as long as its sheath. The root is perennial and fibrous. Joints are smooth, long, and narrow, of a purple tinge. The leaves are flat, sharp, roughish on both sides and serrated on the edge. The Floating Foxtail is found in moist meadows, ditches, ponds, and slow streams, floating on the water.
