Molecular phylogeny of the genus Luzula DC. (Juncaceae, Monocotyledones) based on plastome and nuclear ribosomal regions: A case of incongruence, incomplete lineage sorting and hybridisation

► The subgenus Marlenia occupies the early derived lineage within the genus Luzula. ► The traditionally accepted subgenera Pterodes and Luzula (and its sections) appear to be non-monophyletic. ► Within the Luzula section Luzula, both recent hybridisation and incomplete lineage sorting of ancestral polymorphisms may represent potential sources of the incongruence between chloroplast and nuclear data.
