Narrow species concepts in the Frullania dilatata-appalachianaeboracensis complex (Porellales, Jungermanniopsida): evidence from nuclear and chloroplast DNA markers

We investigated the phylogeny of a Holarctic-Asian group of Frullania species, the Frullania dilatata-F. appalachiana-F. eboracensis complex, using multiple accessions of morphologically circumscribed taxa and three molecular markers (nrlTS region, cp DNA trriL-F and atpB-rbcL regions). Maximum pars...

Description
Summary:We investigated the phylogeny of a Holarctic-Asian group of Frullania species, the Frullania dilatata-F. appalachiana-F. eboracensis complex, using multiple accessions of morphologically circumscribed taxa and three molecular markers (nrlTS region, cp DNA trriL-F and atpB-rbcL regions). Maximum parsimony and likelihood analyses indicated monophyly of morphologically defined taxa. Our phylogenies support a species rather than a subspecies concept within the complex, with four species in North America (F. appalachiana, F. eboracensis, F. parvistipula and F. virginica), and two species in Europe (F. dilatata and F. parvistipula). Accessions of F. dilatata from Southeast Europe and Asia are separated from other European accessions, indicating a former disjunct range of the species.
