|Scientific Name:||Abies vejarii var. macrocarpa|
See Abies vejarii
|Taxonomic Source(s):||Farjon, A. 2010. A Handbook of the World's Conifers. Koninklijke Brill, Leiden.|
|Taxonomic Notes:||This variety is only distinguished by the larger size of its cones. Further collections are necessary to fully evaluate its taxonomic status.|
|Red List Category & Criteria:||Vulnerable D2 ver 3.1|
|Reviewer(s):||Thomas, P., Perez de la Rosa, J. & Rushforth, K.|
As this variety is known from only two localities with a very small area of occupancy, and as wildfires represent a credible threat, an assessment of Vulnerable under the D2 criterion is appropriate.
|Range Description:||Endemic to Mexico, occurring in Coahuila (Mesa de las Tablas) and Nuevo León (Cerro Potosí). The extent of occurrence is less than 2,000 km2 and the area of occupancy of the two known subpopulations is less than 10 km2.|
Native:Mexico (Coahuila, Nuevo León)

|Population:||Only known from two localities and from a few herbarium collections, this variety is either very rare or not recognized (some collections are sterile and cannot be identified to this variety). Population trends are unknown.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Found on high mountains (2,800-3,300 m asl) , presumably occurring with (both) other varieties recognized in this species in oak-pine forest.|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||40|
|Use and Trade:||This taxon is not a commercial timber tree. It is very rare in cultivation.|
|Major Threat(s):||The most likely threat would be devastating wildfires, that could destroy an entire subpopulation.|
|Conservation Actions:||This variety is known from one protected area.|
