Article Synopsis
- Delimiting species boundaries is a complex issue in systematics, especially when dealing with subtle morphological variations that can arise from environmental influences or speciation.
- The Lomatium foeniculaceum species complex, widespread in the western U.S. and Canada, has traditionally been classified into five subspecies, but genetic analysis suggests these may be distinct clades.
- Using molecular data from the Angiosperm353 baits kit, the study identified six monophyletic clades and highlights the need for a reevaluation of taxonomic ranks based on both genetic and morphological traits.
Premise: Speciation not associated with morphological shifts is challenging to detect unless molecular data are employed. Using Sanger-sequencing approaches, the Lomatium packardiae/L. anomalum subcomplex within the larger Lomatium triternatum complex could not be resolved.
