Pinus strobiformis Engelmann
(Southwestern White Pine)

Family: Pinaceae

Status: Native

Synonyms:
Pinus flexilis James var. reflexa Engelmann
Pinus ayacahuite Ehrenberg var. brachyptera Shaw

Pinus strobiformis is similar in appearance to Pinus ponderosa, but the bark is more grayish and cut into squares rather than puzzle pieces. The cones are longer and the needles are more commonly five to a fascicle and somewhat shorter than those of Pinus ponderosa. The seeds of Pinus ponderosa are obviously winged, while those of Pinus strobiformis completely lack wings.
