Distribution
Description
Pinus durangensis is an evergreen tree reaching 25–40 metres (82–131 ft) in height, with a trunk up to 1 metre (3.3 ft) in diameter and a broad, rounded crown. The bark is thick, dark gray-brown, and scaly or fissured.[2]
The leaves are needle-like, dark green, five to seven, rarely eight[3] per fascicle (mostly six, the high regularly occurring number in the genus), 14–24 cm long and 0.7-1.1 mm wide, the persistent fascicle sheath 1.5–3 cm long.[2]
The cones are ovoid, 5–9 cm long, green ripening brown, opening when mature in spring to 5–6 cm broad. The seeds are winged, 5–6 mm long with a 1.5-2.5 cm wing. Pollination is in late spring, with the cones maturing 20–22 months after.
