Quercus affinis

Quercus affinis is a medium-sized evergreen tree which grows up to 16 or 20 meters tall. The leaves are dark green and glossy with toothed edges. Young leaves are sometimes flushed bronze. Trees produce flowers and catkins in the spring, which by autumn mature into small, rounded acorns up to 1.5 cm long. With its laurel-like leaves it can be confused with its close relative Q. laurina, with which it easily hybridizes in the wild.

Quercus affinis ranges through the mountains of eastern Mexico, between 1200 and 2600 meters elevation. Its range includes the Sierra Madre Oriental of Nuevo León, Tamaulipas, San Luis Potosí, Guanajuato, Querétaro, Hidalgo, and Veracruz states, the eastern Trans-Mexican Volcanic Belt of Veracruz and Puebla, and the Sierra Madre de Oaxaca of Puebla and Oaxaca, with some outlying populations in the Sierra Madre del Sur of Guerrero. Quercus affinis is typically found in cloud forest, frequently associated with Liquidambar styraciflua. It also found in oak forests, pine–oak forests, and pine forests. It favors shallow karstic limestone soils with acid pH.

It has gained the Royal Horticultural Society's Award of Garden Merit.
