Pseudotsuga lindleyana
''Pseudotsuga lindleyana'', commonly known as the Mexican Douglas-fir, is a conifer in the genus ''Pseudotsuga'' that is endemic to Mexico. DNA sequence and morphological evidence suggests it is most closely related to Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and might best be treated as an additional variety within ''P. menziesii''.〔
==Distribution==
''Pseudotsuga lindleyana'' is native to the Sierra Madre Occidental, Sierra Madre Oriental, and scattered mountains as far south as Oaxaca.
The Mexican Government lists Mexican Douglas-fir as "subject to special protection" because its populations are small, isolated and show signs of low fertility and recruitment due to inbreeding depression.
