Quercus graciliformis (also known as the Chisos oak or slender oak) is a rare North American species of oak tree in the beech family.[2]

Description

Quercus graciliformis is a deciduous tree up to 8 metres (26 ft) tall. Leaves are elliptical or lance-shaped with 8-10 shallow lobes.[3] The acorns are produced biennially.

Distribution

The species has been found only in the Chisos Mountains, within Big Bend National Park of West Texas, and a few miles southeast into the state of Coahuila in northeast Mexico.[4] It is threatened by habitat loss.[5][6]

It grows on dry, rocky canyon floors at elevations above 5,000 feet (1,500 m).[3]

gollark: People don't seem to use it much. I don't know why. It seems fairly okay.

gollark: Actually, XMPP tried this.

gollark: I feel like that might end up leading to horribleness and large quantities of base64.

gollark: It might be cooler to have IRC with a federated global identity system and server history somehow.

gollark: There's *one* complete implementation versus tens or hundreds for IRC.
