Pinus jeffreyi
Also called Jeffrey Pine, Black Pine
Pinus jeffreyi, also known as Jeffrey pine, Jeffrey's pine, yellow pine and black pine, is a North American species of pine tree. It is mainly found in California, but also in the westernmost part of Nevada, southwestern Oregon, and northern Baja California. It is named in honor of its botanist documenter John Jeffrey.
Pinus jeffreyi occurs from southwest Oregon south through much of California (mainly on the eastern side of the Sierra Nevada), to northern Baja California in Mexico. It is a high-altitude species; in the north of its range, it grows widely at 1,500 to 2,100 m (4,900 to 6,900 ft) altitude, and at 1,800 to 2,900 m (5,900 to 9,500 ft) in the south of its range.
Pinus jeffreyi wood is similar to ponderosa pine wood, and is used for the same purposes. Crystallized sap of P. jeffreyi has been eaten as candy. The exceptional purity of n-heptane distilled from P. jeffreyi resin led to n-heptane being selected as the zero point on the octane rating scale of petrol.
