Pinus ayacahuite is native to Mexico (from Central Mexico southwards to Chiapas), Guatemala, Honduras and El Salvador. It grows on relatively moist areas with summer rainfalls, however specimens from its eastern and southern distribution live under really wet conditions. Despite its tropical origins, it is surprisingly tolerant of cold, having survived the temperatures down to nearly -30 °C in cultivation. Mexican white pine is a large tree, which reaching up to 50 m tall and 2 m in diameter with straight, round trunk that has pyramidal to conical in shape crown with regular branch whorls. The bark are thin, smooth, and ash-grey on young trees, with age becoming rough, gray-brown, divided into small rectangular plates. The branches are long, slender, and horizontally spreading; lower branches often droop. Their needles are in bundles of 5, slender, flexible, 10 - 15 cm long and 0.7 - 1.0 mm wide, straight or slightly twisted, flexible but not drooping. Pollen cones are yellow when young, turning orange-brown with age. Seed cones are yellow-brown, and quite resinous; ripening in the fall and soon deciduous. The seeds are light brown with dark spots.
