Bromus carinatus

Bromus carinatus is a species of brome grass known by the common names California brome and mountain brome.

Description

Bromus carinatus is a perennial bunchgrass growing in clumps tall, with many narrow leaves up to 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 cleistogamy, so that the flowers pollinate themselves, especially under stressful conditions. It also reproduces vegetatively via tillers.
The species is highly variable. It can be easily confused with B. catharticus and B. stamineus.

Distribution and habitat

It is native to western North America from Alaska to northern Mexico, where it can be found in many types of habitat. It is known in parts of the American midwest and eastern North America as an introduced species.

Uses

This grass is used for control of erosion and revegetation of damaged land, as well as a highly palatable forage for livestock; however, it has the capacity to become a noxious weed in agricultural settings.
