Bromus carinatus
is a species of native bunchgrass 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. It is found in every county in California. It is a perennial grass growing in clumps 0.5 to 1.5 meters tall, with many narrow leaves up to 40 centimeters long. The flower cluster 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. It also reproduces vegetatively via tillers. This grass is used for control of erosion and revegetation of damaged land, as well as a highly palatable forage for livestock. In the garden it has a reputation for being short-lived but readily re-seeds. It completes well with non-native weeds, and its sod-building root system makes it useful for erosion control.
