Worldwide phylogeny and integrative taxonomy of <i>Clematis</i>: Insights from phylogenomics.

ABSTRACT: The genus Clematis (Ranunculaceae) comprises over 300 species with remarkable morphological and ecological diversity worldwide. Despite its horticultural, medicinal, and ecological importance, a well-resolved phylogeny and coherent infrageneric classification are still lacking. Here, we reconstruct a robust phylogeny for Clematis using a phylogenomic approach and revise its infrageneric taxonomy. We incorporated 198 samples representing 151 species, two subspecies, and 12 varieties, covering all subgenera and most sections worldwide, obtained from both fresh and herbarium material. Nuclear single nucleotide polymorphisms (SNPs) and complete plastid genomes were assembled for phylogenetic analyses. We also prepared a nuclear ribosomal ITS (nrITS) dataset comprising 171 species
