Quercus chihuahuensis:

Quercus chihuahuensis or Chihuahua oak is a species of oak in the family Fagaceae.[2] It is native to the region from extreme western Texas west to Sonora and south to Zacatecas and San Luís Potosí. It grows mostly at mid elevations (400–2000 m) in forests mixed with various pines and other oaks.[3]

Quercus chihuahuensis is a tree up to 10 m tall, very common in much of its range. 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.[2][4][5]

Comments:

Quercus chihuahuensis is a distinctive species throughout its range, mostly in dry montane western Mexico; it occurs in the United States only as putative hybrids with Q . grisea (the Eagle and Quitman mountains) and Q . arizonica (Hueco Tanks) in Texas.
