Newly described (July 2008) from the Sierra Madre Oriental in northeast Mexico, formerly included in Pinus strobiformis (from the Sierra Madre Occidental in northwest Mexico), from which it differs in relatively shorter, broader cones with different scale shape.

Tree up to 25m tall, with a trunk up to 60cm diameter with grey bark, smooth on young trees, becoming square-cracked with age. Needles in bundles of five, 7-12cm long, outer face glossy green, inner faces with conspicuous blue-white stomatal bands. Cones 12-25cm long, 8-13cm broad when open, green ripening yellow to orange-buff. Seeds large, 13-18mm long, with a vestigial wing.
