Pinus ponderosa var. washoensis (Washoe pine) is a native California tree in the Pinaceae family, recognized by High elevation habitat and very thick needles with smaller, crowded cone scales.
Washoe pine is a native shrub found in the northern Sierra Nevada Mountains, Warner Mountains, and high Cascade Range in upper mixed-conifer to lower subalpine habitats at elevations of 2,000 to 3,000 meters. Its distinctive trunk grows to 35 meters tall with mature bark ranging from medium to dark red-brown, featuring shallow furrows and a short, conic or flat-topped crown. Growing with three needles per bundle, these needles are exceptionally thick and light green with a bluish-gray cast, measuring 12 to 17 centimeters long. The tree produces seed cones 5 to 11 centimeters long, which begin as dark red-purple and mature to green or dark purple, with scales showing intricate brown and black striations. Its distinctive bark and needle structure make it a unique variant of ponderosa pine found in high-elevation mountain environments.

How to tell it apart
vs Pseudotsuga: Pine needles come bundled in groups with papery sheaths; Douglas-fir needles attach individually to smooth twigs.; vs Abies: Pine needles come bundled in groups of 2-5; fir needles attach individually and directly to twigs.; vs Sequoia: Pine has bundled needles in groups of 2-5; redwood has individual scale-like or awl-shaped leaves on flat sprays.; vs Casuarina: Pine has true needles bundled in groups; Casuarina has jointed branchlets with whorls of tiny scale leaves.; vs Cedrus: Pine needles are bundled in tight clusters of 2-5; cedar needles grow in dense rosette-like clusters on short shoots.
