Discussion

In the flora area, subsp. coryae is found in Arizona south of the Mogollon Rim, through central New Mexico to the Chisos and Davis mountains of western Texas. Its principal hosts are Quercus species.

The molecular study by V. E. T. M. Ashworth (2000b) showed that Phoradendron villosum is paraphyletic because P. scaberrimum Trelease forms a clade with subsp. coryae. All three of these taxa parasitize Quercus and a shared indel supported their phylogenetic relationship.
