The dataset consists of sequence alignments for the six DNA markers DHAR2, GAPCP1, GBSSI-2, SbeI, ITS and matK in fasta format for a selected number of cinquefoil species (genus Potentilla, family Rosaceae). The alignments were used in Bayesian Inference analyses and a Multispecies Coalescent analysis, with the aim of resolving the backbone phylogeny of Potentilla

Resolving the evolutionary history of the plant genus Potentilla (Rosaceae) has proven challenging. Previous analyses recovered six subgroups, but the relationships among some of these clades differ between data sets. We studied the incongruences by analyzing four low-copy nuclear markers, in addition to chloroplast and nuclear ribosomal data, with a set of Bayesian phylogenetic analyses. A selective taxon removal strategy demonstrated that the included representatives from the Fragarioides clade, P. dickinsii and P. fragarioides, were the main sources of the instability seen in the trees. When P. dickinsii and P. fragarioides were removed from the dataset, a fully resolved, supported backbone phylogeny of Potentilla was obtained in a Multispecies Coalescent analysis.
