The Chihuahua white pine, Pinus strobiformis, family Pinaceae, is a species of pine tree that occurs in the Sierra Madre Occidental mountains of Northern Mexico, from a short distance south of the US–Mexico border south through Chihuahua and Durango to Jalisco.

It is typically a high-elevation pine, often growing mixed with several other pine species. In favourable conditions, it makes a tree to 30 m, rarely 40 m tall.

Description[edit]

Chihuahua white pine, Pinus strobiformis, is a member of the white pine group, Pinus subgenus Strobus, and like all members of that group, the leaves ('needles') are in fascicles (bundles) of five, with a deciduous sheath. The needles are finely serrated, and 8–14 cm long.

The cones are very large, 16–50 cm long and 9–11 cm broad, and have scales with a very characteristic prolonged and often recurved or S-shaped apex. The seeds are large, and with a very short wing; they are dispersed mainly by birds, particularly the Mexican Jay. It is a very drought tolerant tree but greater populations grow on moist and cool places living in association with Pinus hartwegii and Pinus rudis.


Uses[edit]

The seeds were used as a food by Native Americans in the present day Southwestern United States.

The wood is used in Mexico for furniture and doors.
