Pinus strobiformis Engelm.

Pinus strobiformis Engelm.. Pinus strobiformis, also known as Chihuahua white pine, is a medium-sized white pine tree endemic to western Mexico in the Sierra Madre Occidental mountain range.

It was formerly considered conspecific with Pinus reflexa of the southwestern United States and Pinus stylesii of northeastern Mexico, but is now treated as distinct from these.
