Discussion

Buddleja scordioides is weedy and grows on limestone or gypsum soils in the trans-Pecos region of Texas with Flourensia cernua, Larrea tridentata, and Senegalia greggii, and in semixeric areas in central Arizona and southeastern New Mexico. It occurs also in Mexico, throughout the Chihuahuan Desert and as far south as México, at elevations to 2500 m.
