Bromus carinatus is a species of brome grass known by the common names California brome and mountain brome. It is native to western North America from Alaska to northern Mexico, where it can be found in many types of habitat. Bromus carinatus is a perennial bunchgrass growing in clumps 0.5 to 1.5 meters tall, with many narrow leaves up to 40 centimeters long. The inflorescence is a spreading or drooping array of flat spikelets longer than they are wide. The grass is wind-pollinated but is also sometimes cleistogamous, so that the flowers pollinate themselves, especially under stressful conditions. This grass is used for control of erosion and revegetation of damaged land (Wikipedia).
