Discussion
Bothriochloa wrightii grows in rocky grasslands and shrubby slopes of the pine-oak woodlands of southern Arizona, New Mexico, Texas, and northern Mexico, at 1200-1800 m. It was last collected in the United States in 1930. It differs from B. barbinodis in its glaucous foliage, short, fan-shaped panicles, and large, pedicellate spikelets.
