Abstract

This article focuses on the taxonomic revision and species delimitation within the Eryngium anomalum species complex, a group of annual herbs endemic to coastal central-northern Chile. Using an integrative approach combining morphological, geographical, climatic, and molecular data, the study supports the recognition of three distinct species within the complex, including a newly described species named Eryngium atacamense. These species—E. anomalum, E. coquimbanum, and E. atacamense—are differentiated by fruit morphology, reproductive traits, geographic distribution, and climatic niches, with divergence likely driven by Quaternary climatic fluctuations and varying aridity in the Chilean Mediterranean and Atacama Desert regions. Coalescent-based genetic analyses confirm strong genetic structure among the three lineages, consistent with their status as independent species.
