Knobcone Pine - Pinus attenuata
Most easily identified by the asymmetric cones that may remain on the tree for years, Knobcone Pine is a primarily a species of open, hilly woodlands near the Oregon and California coasts; it also grows in the lower elevations of the Sierra Nevada. It is mostly confined to poor soils. The cones are borne in clusters and may become embedded in the trees and remain closed until fire sweeps the area. The needles are in bundles of three and are quite sparsely distributed along the branches. The bark is shallowly furrowed on old trees. The trunk may be crooked and forked.
