				Jointed Goatgrass - Aegilops cylindrica Family: Poaceae THIS PAGE IS UNDER CONSTRUCTION Status: Invasive Location info: Jointed goatgrass if found in the wheat producing areas of the Pacific Northwest. It is known to occur in every county in Eastern Washington. This plant was introduced from Europe into the United States in the early 1900's, and reported in the Pacific Northwest in 1917. Jointed Goatgrass is a noxious weed in Idaho, Oregon, Utah, and California, as well as Washington. Info: Jointed goatgrass is a winter annual grass, vegetatively similar to wheat in the seed stage. The leaves are alternately arranged with auricles at their base and occasional hairs extending along the margins. The flower spike is cylindrical and distinct from wheat. Two to four flowers are arranged in each of the spikelets which form the elongate cylindrical spike. It is jointed in appearance and each joint contains one to three seeds. The glumes on the top spikelet have long awns. The seed of jointed goatgrass ripens before winter wheat and shatters easily.
