Multi-disciplinary evidence illuminates the speciation history of a monophyletic yet dimorphic lily group.

ABSTRACT: Species boundaries are dynamic and constantly challenged by gene flow. Understanding the strategies different lineages adopt to maintain ecological and genetic distinctiveness requires employing an integrative species concept that incorporates data from a variety of sources. In this study, we incorporated genetic, ecological, and environmental evidence to assess the extent of speciation or evolutionary divergence within a monophyletic yet dimorphic group (i.e., clade Leucolirion consisting of six species) within the genus Lilium. This clade consists of two lineages that exhibit unexpectedly distinct perianth appearances: whitish trumpet (funnel form, encompassing four species) and orange recurved (reflex form, including two species), respectively, which are separated by completely d
