Quercus chihuahuensis, the Chihuahua oak, is a species of oak in the beech family.[1] It is native to the region from extreme western Texas west to Sonora, Mexico, and south to Zacatecas and San Luis Potosí. It grows mostly at mid elevations, from NaNm (-2,147,483,648feet) above sea level, in forests mixed with various pines and other oaks. It is one of the dominant species of the Sierra Madre Occidental in Chihuahua and Sonora.[2] [3] [4]
The tree grows up to 10 m (33 ft) tall, very common in much of its range. The leaves are entire to toothed or sublobate, green on the top but yellow or gray on the underside because of a coating of velvety, stellate (star-shaped, highly branched) hairs. The species is related to Quercus arizonica and Quercus grisea, sometimes hybridizing with these two species in Texas.[1] [5]
