''Hordeum brachyantherum'', known by the common name meadow barley, is a species of barley. It is native to western North America from Alaska to northern Mexico, coastal areas of eastern-most Russia (Kamchatka), and a small area of coastal Newfoundland. The diploid cytotype occurs only in California, throughout the state, while everywhere else plants are tetraploid. This is a tufting perennial bunchgrass approaching a meter in maximum height. It produces compact, narrow inflorescences 8 to 10 centimeters long and purplish in color. Like other barleys the spikelets come in triplets. It has two small, often sterile lateral spikelets on pedicels and a larger, fertile central spikelet lacking a pedicel. ==External links== *(Jepson Manual Treatment ) *(USDA Plants Profile ) *(Photo gallery ) 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「Hordeum brachyantherum」の詳細全文を読む スポンサード リンク
