摘要

Argemone pleiacantha subsp. pinnatisecta (Sacramento Prickly Poppy) is a federally listed endangered member of Papaveraceae, known from a few small populations on the western slope of the Sacramento Mountains in Otero County, New Mexico. With the total number of established A. pleiacantha subsp. pinnatisecta apparently dwindling, and threats to the viability of the taxon coming from a variety of factors, the taxonomic status of this group is of interest to scientists and land managers. The objective of this study was to test whether Argemone pleiacantha subsp. pinnasecta is diagnosable at the level of species through the application of an AFLP-based molecular assessment of population-level variation. Results front principle coordinate and STRUCTURE analyses on 424 AFLP loci, taken from samples of Argemone pleiacantha subsp pinnatisecta and related geographically proximate members of Argemone, identify that the Sacramento Prickly Poppy is a genetically unique population system. The results of the AFLP analysis, in combination with the geographic isolation and morphological differentiation, are consistent with applicable widely held concepts of plant species. A new combination. Argemone pinnatisecta (G.B. Ownbey) S.D. Cervantes & C.D. Bailey comb. et stat. nov., is presented.
