stylesii is a mountain pine endemic to the isolated high ranges around Cerro Potosí in Nuevo León and adjacent Coahuila. veitchii, to have a strong affinity for the moist airmasses associated with the Gulf of Mexico circulation, and its western range limit corresponds to a steep gradient in summer precipitation.įinally, P. veitchii (covering most of Hidalgo and some adjacent areas), is sympatric with another white pine, P. veitchii do not have contiguous ranges there is a large range gap between southern Durango and western Michoacán broken only by a tiny isolated population of P.
Cones were collected and photographed by Jeff Bisbee in habitat, and he has also provided the descriptive text. The following table shows mature seed cones collected at sites widely dispersed across the region, representing each of the taxa named above. reflexa is a name of convenience for, mostly, strobiform white pines of Arizona and New Mexico. strobiformis, and those characters show a fairly smooth transition between the two endpoints, so that there is no clear transition from one taxon to the other as such, P. One is sometimes called Pinus reflexa, distributed from southwest Colorado to northern Sonora, Chihuahua, Coahuila, and west Texas it displays morphological, molecular and ecological characters intermediate between P. Intermediate forms occur between each of these taxa. stylesii, a narrowly distributed montane and subalpine endemic of the northern Sierra Madre Oriental. veitchii, a montane species of the moist eastern Transverse Volcanic Plateau and strobiformis (type subspecies), a primarily montane species of the Sierra Madre Occidental, ranging up into the southwestern U.S. flexilis, a species of cold country, mainly high mountains in Canada and the western U.S. strobiformis is at the heart of a white pine species complex that extends from Alberta to the Transverse Volcanic Plateau of Mexico, and which includes the species here described as: There is one described subspecies, Pinus strobiformis Engelmann subsp. It is a typical white pine in section Strobus, with close affinities to several other New World white pines, discussed below. strobiformis (Engelmann) Lemmon ( Kral 1993). Mexican white pine, Arizona white pine, Chihuahuan white pine, southwestern white pine pino blanco, pinabete, pino enano.
