Bromegrass

Bromegrass, any of about 60 kinds of grass of genus Bromus, found mostly in the Northern Hemisphere and including both weed grasses and grasses valuable as pasturage and soil binders. Plants have flat thin leaves 12–40 in (30–100 cm) tall, often with drooping flower clusters. Rescue grass (B. unioloides) and smooth brome (B. inermis) are the most economically important varieties. Some weed varieties, such as ripgut grass (B. rigidus) and foxtail brome (B. rubens), have spines on the flower clusters that can cause serious internal and external injury to grazing animals.
