Generic delimitation in the Cyphotheca-Plagiopetalum-Sporoxeia clade
The Cyphotheca-Plagiopetalum-Sporoxeia clade (Sonerileae, Melastomataceae) comprises Cyphotheca Diels, Plagiopetalum Rehder, Sporoxeia W.W.Sm., certain species currently treated in the highly polyphyletic Phyllagathis Blume, as well as some undescribed species, which requires taxonomic revision at the generic level. In this study, we expanded taxon sampling of the CPS clade and reconstructed phylogenetic relationships using genomic SNPs and whole plastomes assembled from genome resequencing data.
