Abstract
Abstract? Taxonomic problems in Mentzelia section Bartonia (Loasaceae) are addressed using phylogeny reconstructions based on nuclear
ribosomal DNA sequences from the ITS and ETS regions. Our results indicate sect. Bartonia is monophyletic and consists of two wellsupported,
species-rich clades. One of these two deepest clades consists of the Great Plains M. decapetala and a group of species centered in the
North American intermountain region that have been described as subshrubby; whereas, the second deepest clade is more widespread and
includes taxa from the Chihuahuan and Sonoran deserts as well as the Great Plains, Rocky Mountains, and intermountain region. Hypothesis
tests applying the Shimodaira-Hasegawa (SH) test and Bayes factors (BF) rejected unequivocally the monophyly of (1) the ?subshrubby? group,
suggesting multiple origins of the ?subshrubby? form; (2) M . multicaulis s. l., which consists of disparate clades we propose as separate species;
and (3) M . multiflora s. l., which was recovered as highly polyphyletic. Hypothesis tests were equivocal, however, in regard to the monophyly
of (1) M . marginata , M. paradoxensis , and M . cronquistii ; (2) M . oreophila s. l.; and (3) M. pumila s. l. We suggest following narrow taxonomic
approaches to the circumscriptions of M . multicaulis , M . multiflora , and M. pumila and advocate further studies of M . oreophila and the complex
including of M . marginata , M. paradoxensis , and M . cronquistii . Our results provide the most comprehensive phylogenetic hypothesis of sect.
Bartonia to date, however, more variable markers will be needed to resolve a well supported phylogeny.
