Quercus candicans

Quercus candicans is a Mesoamerican species of oak tree. It is native to central and southern Mexico (Chihuahua, Chiapas, Colima, Durango, Guerrero, Guanajuato, Hidalgo, Jalisco, Mexico City, Mexico State, Morelos, Nayarit, Oaxaca, Puebla, San Luis Potosí, Sinaloa, Sonora, Veracruz) and Guatemala. It grows from 1,200 to 2,700 metres (3,900 to 8,900 feet) in altitude in wet montane forests, preferring calcareous soils.[2][3][4][5]

  • Quercus alamo Benth
  • Quercus calophylla Schltdl. & Cham.

It is a deciduous tree growing 8 to 25 m (26 to 82 ft) tall[5] with a trunk as much as 100 centimetres (39 inches) in diameter. The leaves are stiff and leathery, rigid, up to 23.5 cm (9+1⁄4 in) long, egg-shaped with numerous pointed teeth along the edges.[2]

In 2018, it was found that the type specimen of Quercus candicans was actually a misidentified Roldana, a plant in the aster family (Asteraceae). Therefore, the correct name of this species would actually be Quercus calophylla.[6]
