Species of Valerianaceae are a common component of the alpine flora throughout the Northern Hemisphere as well as the Andes of South America. Sequence data from three chloroplast markers (psbA-trnH intron, trnK-matK intron, and the trnL-F region) along with the internal transcribed spacer region (ITS) of nuclear ribosomal DNA were used to infer relationships within Valerianaceae. Both genomes, ...

We explore patterns of diversification in the plant clades Adoxaceae and Valerianaceae (within Dipsacales), evaluating correlations between biogeographic change (i.e., movements into new areas), morphological change (e.g., the origin of putative key innovations associated with vegetative and reproductive characters), and shifts in rates of diversification. Our findings indicate that rates of di...

To further clarify phylogenetic relationships within Dipsacales,we analyzed new and previously published rbcL sequences, alone and in combination with morphological data. We also examined relationships within Adoxaceae using rbcL and nuclear ribosomal internal transcribed spacer (ITS) sequences. We conclude from these analyses that Dipsacales comprise two major lineages:Adoxaceae and Caprifolia...

The Morinaceae (Dipsacales) contains 13 species placed in Acanthocalyx, Cryptothladia or Morina, and is distributed from the mountains of southeastern Europe through the Himalayas to the Qinghai-Tibetan Plateau, mainly in alpine habitats. Sequence data from two chloroplast regions (the trnK intron and the trnL-F region) and the internal transcribed spacer (ITS) region of nuclear ribosomal DNA w...

The southern Andean clade of Valeriana provides an excellent model for the study of biogeography. Here we provide new data to help clarify phylogenetic relationships among the South American valerians, with special focus on taxa found in the southern Andes. We found that the southern Andean taxa formed a clade in maximum likelihood and maximum parsimony analyses, and used a Bayesian relaxed clo...
