About Quercus jonesii Trel.
Quercus jonesii Trel. is a small tree that usually grows to a height of 4 to 8 metres, or 13 to 26 feet. This species is native to the Sierra Madre Occidental, the Sierra Madre Oriental, and smaller ranges of the Mexican Plateau located between the two mountain ranges. It occurs across the Mexican states of Aguascalientes, Chihuahua, Durango, Guanajuato, northern Jalisco, eastern Nayarit, San Luis Potosí, Nuevo León, Sinaloa, and Sonora. Quercus jonesii grows in pine-oak forests, oak forests, and both oak and pine-oak woodlands. It most often grows in isolated patches on well-drained rocky slopes located in otherwise humid areas. It is frequently associated with three other oak species: Quercus eduardi, Quercus resinosa, and Quercus laeta.
