Taxonomic and ecologie relationships between Picea glauca and Picea engelmannii
Comparisons have been made of the morphologic characters of 30-tree populations of Picea distributed from near the Arctic Circle in Alaska, to near the southern boundary of Arizona. Included are 7 populations of P. glauca beyond the geographic range of P. engelmannii, 12 populations of P. engelmanni...
