Examining the Uniqueness of the Ponderosa Pines of the Transverse Ranges and the eastern Sierra Nevada.

Southern California is geographically and geologically complex and is considered a biodiversity hotspot for many species. The California ponderosa pines (Pinus ponderosa) that grow to the south and east of the Sierra Nevada were first noted as being distinctive in the late 1970’s by researchers using monoterpenes as evidence. More recently, a distinctive mitochondrial haplotype was reported that shows that these populations do not fit with either P. ponderosa var. ponderosa or with P. ponderosa var. scopulorum. Their relationship to species in Mexico is presently unknown. Additionally, there is a potential for hybridization between P. ponderosa and P. jeffreyi where the two species are sympatric. We use plastid simple sequence repeats and mitochondrial haplotypes to examine the similarity of these populations to P. jeffreyi and to each of the Mexican Ponderosae species.
