Hordeum intercedens
is an uncommon species of wild barley known by the common names bobtail barley and vernal barley. It is native to southern California and northern Baja California, where it is an increasingly rare member of the flora in saline and alkaline soils near seasonal waterflows and vernal pool habitat. Today most occurrences are located on the Channel Islands of California; many of the occurrences known from the mainland have been extirpated in the process of land development. This is an annual grass growing erect to bent in small tufts with stems up to 40 centimeters long. The flower cluster is a green spike up to 6.5 centimeters long made up of awned spikelets between 1 and 2 centimeters long.
