Abstract
DNA sequence data from nuclear ribosomal internal transcribed spacer, including the 5.8s coding region, and plastid trnK/matK were used to reconstruct the phylogeny of Montieae (Portulacaceae), and a new taxonomy for Montieae based on monophyly is proposed. Montieae consists of the sister clades Claytonia and Montia. In Claytonia, there is strong support for the following clades: sect. Limnia, all annuals except the perennials C. sibirica and C. palustris; sect. Rhizomatosae, high elevation or high latitude perennials with rhizomatous or caudicose growth habits; and sect. Claytonia, species with spheric or obconic underground perennation structures. All analyses recover clades of Montia circumscribed as sections Montiastrum, Australiensis and Montia. Heenans australasian Neopaxia is placed robustly in Montia sect. Australiensis, a clade limited primarily to Australia and New Zealand. The ancestral area for Montieae is reconstructed as western North America. Beringian taxa of Claytonia sect. Rhizomatosae are derived from low latitude western North America ancestors adapted to persistently wet, alpine habitats. Although we infer that sect. Claytonia had multiple shifts to northern high latitudes and potentially to eastern North America from western North America, relationships among clades in this section have limited support. Habitat reconstructions show that the pleisiomorphic condition for moisture regime in sect. Claytonia is largely maintained over shifts in elevation/latitude.
