TAXONOMY : 
The currently accepted scientific name of western larch is Larix
occidentalis Nutt. [59].  All ten species of larch (Larix spp.) are
found in cool areas of the Northern Hemisphere [40].  Where the ranges
of western larch and alpine larch (L. lyallii) overlap, alpine larch
grows at higher elevations.  Wherever these two larch species are
sympatric, natural hybrids occur [58,72,118].  Western larch has been
successfully crossed with Japanese larch (L. leptolepus) [118].  Western
larch has much genetic flexibility or variability within populations and
relatively little variation or differentiation between populations
[98,99].
