Pinus cembroides
Pinus sabiniana
Pinus cembroides is the common pinyon of Mexican commerce. Populations of the Edwards Plateau, Texas, are disjunct about 150km east and north of the main area of distribution of the species, and they have been described as a distinct variety, P. cembroides var. remota Little, on the basis of thin seed shell and a higher frequency of 2-leaved fascicles in contrast to the thicker seed shell and prevalently 3-leaved fascicles in Mexican pinyon populations to the west and south. The strong overlap in nearly all character states between the populations of the Edwards Plateau and other populations makes var. remota difficult to maintain.

Seeds of Pinus sabiniana were an important food source for many Indian groups in California, sometimes collectively referred to as "Digger Indians." Because the name "Digger" has been used as a derogatory ethnic term, many people prefer to avoid using the vernacular name Digger pine.
