TAXONOMY : 
The genus Picea consists of about 30 species of evergreen trees found in
cool, temperate regions of the northern hemisphere.  Seven species of
Picea, including Engelmann spruce, are native to North America.  The
currently accepted scientific name of Engelmann spruce is Picea
engelmannii Parry ex Engelm. [45,53].  There are no recognized races or
geographic varieties.

Natural hybridization between species of Picea is common.  Engelmann
spruce x white spruce (Picea glauca) hybrids are common where the ranges
of these species overlap.  Natural crosses between these species occur
from central British Columbia as far south as eastern Washington and
Yellowstone National Park [23].  Within this area, trees at low
elevations closely resemble pure white spruce.  Pure Engelmann spruce
tends to dominate at higher elevations [23].  Engelmann spruce x white
spruce hybrids are common throughout low elevations in British Columbia
[32].

Using artificial pollination techniques, Engelmann spruce has been
successfully crossed with white spruce, blue spruce (P. pungens), and
Sitka spruce (P. sitchensis) [32].
