Tree to 35(-50) m tall, with trunk to 0.9(-1) m in diameter. Bark grayish brown, with long, flat-topped ridge separated by deep furrows. Crown conical at first becoming cylindrical or dome-shaped, often remaining fairly dense, with numerous slender, horizontal branches well clothed with foliage at the ends. Twigs light brown, occasionally thinly waxy, hairless, the bases of the scale leaves fairly smooth, flaking away completely after the first year. Buds 12-20 mm long, not resinous. Needles in bundles of (four or) five (or six), each needle (15-)20-28(-35) cm long, thin, flexible, and drooping, lasting 2(-3) years, light yellowish green to bluish green. Individual needles with just a few lines of stomates on all three faces, and two or three (or four) resin canals at the corners of the needles midway between the needle surface and the two-stranded midvein and separated by bands of hard, dense, colorless sclereids. Sheath 11-19(-25) mm long, persisting and falling with the bundle. Pollen cones 3-4 cm, light reddish brown. Seed cones (4-)6-9(-12) cm long, egg- to broadly egg-shaped, slightly asymmetrical and curved, with 45-120(-160) seed scales, green before maturity, ripening light reddish brown, opening widely to release the seeds and then falling together with the stout, curved, 10-15 mm long stalks. Seed scales roughly rectangular, the exposed face diamond-shaped, scarcely raised, with a small umbo bearing a slender, fragile prickle. Seed body 4-7 mm long, the clasping wings another (13-)16-22 mm longer.

Mountains of central and southern Mexico and northern Central America, from southern Sinaloa and Puebla (Mexico) south to Jinotega (Nicaragua). Mixed with other pines and evergreen or deciduous hardwoods in many kinds of forests, woodlands, and savannas; (450-)800-2,000(-2,800) m.
