Quercus elliptica

Quercus elliptica is a tree growing up to 15 metres (49 feet) tall with a trunk as much as 70 centimetres (28 inches) in diameter. The leaves are thick and leathery, up to 12 cm (4+3⁄4 in) long, elliptical with wavy edges but no teeth or lobes.[3][8]

Quercus elliptica is found in oak forests, cloud forests, and pine–fir (Abies) forests from 300 to 2400 meters elevation. It is mostly restricted to granite soils. Quercus elliptica is often dominant and common where it is found.[1]

Quercus elliptica ranges across central and southern Mexico. Its range extends from the central Sierra Madre Occidental of Sinaloa in the northwest through western Nayarit, including Sierra de San Juan, and western Jalisco, including the Sierra de Vallejo and Sierra de Manantlán. It also ranges through the Sierra Madre del Sur and Sierra Madre de Oaxaca of Guerrero and Oaxaca states. There are populations in the Trans-Mexican Volcanic Belt of Michoacán and Mexico states. In Chiapas it is found in the Sierra Madre de Chiapas and Chiapas Highlands, including Lagunas de Montebello National Park.[1]

There are only two citations in Guatemala, in the Sierra de las Minas and in Camotán. It is also found in the Maya Mountains of Belize, and in the highlands of El Salvador, Honduras, and Nicaragua.[1]

Because of its wide range and abundant populations it is rated Least Concern. Despite habitat loss in parts of its range its population is considered stable.[1]

Phytophthora cinnamomi, the fungal parasite known as Sudden Oak Death, has been found in Quercus elliptica.[1]
