Picea lutzii

Picea × lutzii - Lutz spruce

In a few restricted areas of north-western North America, in Alaska and north-western British Columbia, the ranges of the continental white spruce (P. glauca) and the extremely maritime sitka spruce (P. sitchensis) overlap. In these areas, the American H. J. Lutz discovered this intermediate form, which is named after him, in the 1950s.
