Description

Tree to 20(-25) m tall, or shorter southward, with trunk to 0.7(-0.8) m in diameter. Bark thick, dark grayish brown, broken up into broad, rough, interrupted ridges by deep, wide, reddish brown furrows. Crown dome-shaped to cylindrical, with numerous slender, horizontal to gently rising branches sparsely clothed with foliage at the tips. Twigs reddish brown with a dusting of wax, hairless, channeled between the long scale leaf bases which begin to peel off after the second year. Buds 8-15 mm long, not conspicuously resinous. Needles in bundles of (two or) three (or four), each needle (7-)10-15(-19) cm long, stiff and straight, lasting 2-3 years, bright light green. Sheath 12-20(-23) mm long at first, rupturing and weathering to (5-)10-15 mm and then persisting and falling with the bundle. Pollen cones 1-2 cm long, yellowish brown. Seed cones (2.5-)4-6(-7) cm long, egg-shaped to conical when fully open, sometimes slightly asymmetrical and curved, with 50-100 seed scales, green before maturity, ripening light brown, opening widely to release the seeds and then falling or persistent for a while before falling with the short, stout stalk 5-8(-12) mm long. Seed scales paddle-shaped, the exposed face horizontally diamond-shaped, only slightly raised, crossed by a ridge, the umbo large, flat to pointed and bearing a fragile prickle. Seed body 3-5 mm long, the clasping wing another (8-)10-15 mm longer.

Mountains throughout Mexico, from western Chihuahua and northern Coahuila to southeastern Chiapas. Forming pure stands or mixed with other pines and oaks in open forests and woodlands; 1,000-3,000(-3,300) m.
