Stems are leafy, branched and 4 to 6 inches tall. Under favorable conditions, stems may be 12 to 18 inches high. Stems are short jointed. Leaves are flat and spreading. The ligule is a circle of white hairs. Leaves may be hairy or smooth. Seed heads are usually in one whorl of 3 to 7 spikes, each about 1 to 2 1/2 inches long. Some robust forms may have up to 10 spikes in 2 whorls. There are approximately 2,071,000 hulled seeds per pound.
