Pinus hartwegii
Also called Mexican mountain pine
Pinus hartwegii (syn. P. rudis, P. donnell-smithii), Hartweg's pine, the Mexican mountain pine, or pino de las alturas, is a pine native to the mountains of Mexico and Central America east to Honduras. It is named after Karl Theodor Hartweg, who described it in 1838.
Pinus hartwegii is a very high elevation species, growing at elevations of 2,500–4,300 metres (8,200–14,100 ft). It forms the alpine tree line on most of Mexico's higher mountains. It grows on both the Sierra Madre Occidental and Sierra Madre Oriental (mountain ranges) (29° North latitude) from Chihuahua State and Nuevo León (26°) to the highest peaks in the mountain ranges on the El Salvador—Honduras border (15° North latitude). In the Sierra Madre Occidental this pine grows with very dry winters and a very heavy rainy season in summer, with constant frosts from October to March.
