Pinus arizonica var. stormiae
Pino real, pino blanco [Spanish] (Perry 1991).
Syn: Pinus ponderosa D. Douglas ex P. Lawson var. stormiae (Martínez) Silba 1990 (Farjon and Styles 1997).
Mexico: Coahuila, Nuevo León, southwest Tamaulipas (Miquihuana) and parts of San Luis Potosí (Perry 1991).
Have seen it in the Sierra Peña Nevada of southern Nuevo León, and in extensive stands on the plains south of and at mid-elevations on Cerro Potosí, also in Nuevo León. Within its range it is a common and conspicuous pine.
This species is one of many principal hosts for the dwarf mistletoe Arceuthobium vaginatum subsp. vaginatum, and is also a principal host for A. vaginatum subsp. cryptopodum (Hawksworth and Wiens 1996).
