Pinus arizonica Engelmann 1879

Common Names

Taxonomic notes

Three varieties: arizonica, cooperi, and stormiae.

"Engelmann (1879) stressed the difference in leaf number with P. ponderosa (5 vs. 3), but found it otherwise very similar to certain forms of that species. Shaw (1909, 1914) reduced it to a variety of P. ponderosa when it became known that the 'leaf-fascicles (are) heteromerous, with the larger number in the southern parts of its range (referring to P. ponderosa s.l.)... P. arizonica has often been treated under [p. ponderosa] as a variety, but more recent treatments recognize it as a distinct species, with possible introgression in Arizona and New Mexico" (1).
