INTRODUCTORY
FEIS ABBREVIATION:PSEMENG SYNONYMS:Pseudotsuga menziesii var. glauca (Beissn.) Franco [120] Pseudotsuga menziesii var. glauca (Mayr) Franco [90] NRCS PLANT CODE [257]:PSMEG COMMON NAMES:Rocky Mountain Douglas-fir inland Douglas-fir interior Douglas-fir [116] TAXONOMY:The currently accepted scientific name of Douglas-fir is Pseudotsuga menziesii (Mirbel) Franco (Pinaceae) [90,138,265]. This FEIS summary focuses Rocky Mountain Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Mayr) [138,265]. Coast Douglas-fir (Pseudotsuga menziesii var. menziesii) is the other recognized variety [120,138,265]. Intermediate forms and "clinal variation" in some characteristics exist where the varieties' ranges overlap [196]. There is also much variation within Rocky Mountain Douglas-fir [53], but analyses of variation in volatile leaf oils [221] and at enzyme loci have shown that splitting of varieties is in accord with the species' phylogeny. However, 1 population in Mexico did not cluster with either variety in the genetic analysis at enzyme loci [155]. Information presented in this species summary pertains to Rocky
Mountain Douglas-fir, and the variety will be referred to by its full common name.
When information pertains to the species as a whole, the common name Douglas-fir
is used.
