Phylogeny based generic reclassification of <i>Muscari</i> sensu lato (Asparagaceae) using plastid and genomic <scp>DNA</scp>

The grape hyacinth (Muscari) represents an important ornamental plant group in Asparagaceae subfamily Scilloideae, comprising some 80 species distributed mainly the Mediterranean. However, genus delimitation has repeatedly shifted over past two centuries and a general consensus not been reached so far. present study investigates phylogeny of Muscari s.l. (i.e., including disputed segregates Pseudomuscari Leopoldia) with broad sampling about half currently recognized using both chloroplast markers (trnK(matK)-psbA, trnL-trnF, rpl16) genome-wide single nucleotide polymorphism (SNP) data generated by double-digest restriction site-associated DNA sequencing (ddRAD). We perform concatenated maximum likelihood inference for datasets as well coalescent-based approach principal component analysis (PCA) on ddRAD data. find that morphological characters traditionally used to distinguish different genera are diagnostic clades here retrieved. Also, Leopoldia deeply nested we therefore propose broadly defined five subgenera. subgenera roughly correspond previously entities, exception newly identified clade proposed M. subg. Pulchella nov. provide provisional assignment accepted taxa these
