Pinus teocote
Mexico, Guatemala (Farjon and Styles 1997). See also Thompson et al. (1999).
Although this species is in principle widely distributed, I have found it to be uncommon in much of its range, becoming a dominant forest component only on the Transverse Volcanic Plateau and north of there along the Sierra Madre Oriental. It can be found easily near the town of San Miguel in San Luis Potosí (see photos at left), where it grows in the company of fine examples of Pinus montezumae and P. greggii var australis (the latter being very limited in its distribution).
This species is a principal host for the dwarf mistletoes Arceuthobium globosum subsp. grandicaule (in southern Mexico), Arceuthobium rubrum (in Durango and Sinaloa), and A. nigrum, the latter having been described from a collection on this species 51 km E of El Salto on highway 40, the Durango-Mazatlan highway (Hawksworth and Wiens 1996). See the "Remarks" in Abies durangensis for a relevant story.
