''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. It is known in parts of the American midwest and eastern North America as an introduced species. ==Description== ''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. It also reproduces vegetatively via tillers. This species is highly variable. It can be easily confused with B. catharticus and B. stamineus. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bromus carinatus」の詳細全文を読む スポンサード リンク
