Jointed goatgrass is a winter annual that can reach 4 ft. (1.2 m) in height. The leaves are alternate, up to ½ in. (1.2 cm) wide with thin hairs along the margins, sheath openings and auricles. The ligule is short and membranous. Flowering occurs in May to June, when the plants produce red (when mature) or straw-colored spikes. Spikes are cylindrical and contain 2-12 spikelets per spike. The uppermost spikelets have extremely long awns. Jointed goatgrass is native to southern Europe and western Asia. This species is known to hybridize with wheat.
