ABBREVIATION : PINCEM SYNONYMS : Pinus discolor Bailey & Hawksworth [20,76,77] Pinus lagunae Passini [3] Pinus orizabensis Bailey & Hawksworth [3] Pinus remota (Little) Bailey & Hawksworth [28,88,94] SCS PLANT CODE : PICE COMMON NAMES : Mexican pinyon border pinyon papershell pinyon TAXONOMY : The currently accepted scientific name of Mexican pinyon is Pinus cembroides Zucc. It is a member of the pine family (Pinaceae) [16,41,98]. Two varieties in addition to the typical variety are recognized: papershell pinyon (P. c. var. remota Little) and Mexican pinyon (P. c. var. bicolor Little) [44,79,88]. There is taxonomic disagreement about P. cembroides in the strict sense. Bailey and Hawksworth and others have split P. cembroides infrataxa and raised them to specific status [3,20,30,77,70,94]. Two subspecies (P. c. ssp. lagunae D. K. Bailey and P. c. ssp. orizabensis D. K. Bailey) beside the typical subspecies of P. cembroides were recognized; however, recently each was raised to specific status [3,70]. The two varieties, P. c. var. remota and P. c. var. bicolor, were synonomized to P. remota (Little) Bailey & Hawksworth and P. discolor Bailey & Hawksworth (border pinyon), respectively [20,30,47,77,94]. All names are currently used in the literature. Bailey and Hawksworth relegated P. c. var. bicolor to synonomy with P. discolor based on differences in flowering times, bark color, needle color and number, and two monoterpene compounds [70]. Variation in flowering time and needle number throughout the revised range of P. cembroides is inclusive of P. discolor characters [1,16]. Therefore, this writeup considers P. cembroides in the broad sense. For readers who support the realignment, studies concerning United States populations of P. cembroides may be interpreted as P. discolor [29,57,76]. Hybrids occur between Mexican pinyon and true pinyon (P. edulis) where their ranges overlap [29]. LIFE FORM : Tree FEDERAL LEGAL STATUS : No special status OTHER STATUS :
