Pseudotsuga menziesii var. lindleyana, commonly known as the Mexican Douglas-fir, is a conifer in the genus Pseudotsuga that is endemic to Mexico.[1] DNA sequence[2] and morphological[3] 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.[1]
Distribution
Pseudotsuga menziesii var. 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"[4] because its populations are small, isolated and show signs of low fertility and recruitment due to inbreeding depression.[5][6]
