Tree to (20-)40 m tall, with trunk to 1(-1.5) m in diameter. Bark gray, darkening, reddening, and becoming deeply furrowed with age. Branchlets hairless or with short hairs in the deep grooves between the leaf bases.  Buds 4-5 mm long, resin-coated.

Seed cones cylindrical, 5-9(-11) cm long, 3-4(-4.5) cm across, green when young, maturing yellowish brown. Seed body 6-8(-10) mm long, the wing 1.5-2 times as long.

Has been found in two disjunct populations in the Sierra Madre Oriental, in Coahuila and Nuevo León: the Sierra de la Madera and to the SE of this location in mountains near General Cepeda and in the Sierra de Arteaga and Sierra de La Marta. Here the altitude range is 2,100-3,550 m, higher than in the western range of this species; at its lower sites it is confined to shady canyons and only on the highest ridges and summits can it exist on more open slopes, forming dense forests usually mixed with other conifers.


Conservation Status

Red List Category & Criteria: Vulnerable

(Abies durangensis var. coahuilensis is known from two locations: in the Sierra de la Madera it occurs in canyon systems and on a summit, and in SE Coahuila it is known from a few mountain summit areas. Its total area of occupancy (AOO) is probably less than 30 km² and forest wildfires could seriously deplete these stands and result in a Critically Endangered listing. As a result it is assessed as Vulnerable)
