Pinus cembroides Zucc.
Mexican Pinyon, Mexican Pinyon Pine, Pinyon, Nut Pine, Border Pinyon
Pinaceae (Pine Family)
USDA Symbol: PICE
Mexican pinyon is a small, bushy evergreen, usually 15-30 ft. tall, with a compact, rounded crown and rich, blue-green needles occurring in bundles of three. Small, resinous tree with short trunk and spreading crown of low, horizontal branches and thick-walled, edible seeds; often shrubby.
The hard seeds are the main commercial pinyon nuts (pinones) of Mexico. However, in the United States this species has limited distribution and usually bears light cone crops; other species with thin-walled seeds are more common. Rodents, especially "packrats," eat the seeds.
