Discussion

Berlandiera lyrata is cultivated in Arizona. Exceptional specimens that are scapiform (sometimes monocephalic) with mostly undivided leaves and with wartlike hairs on peduncles occur at higher elevations (south-central New Mexico, trans-Pecos Texas, and Nuevo León). They have yellow disc corollas, as do most collections from Chihuahua, Durango, Nuevo León, and Tamaulipas.
