Phylogenetic relationships within Nama L. (Boraginaceae) inferred from nuclear and chloroplast data.

The genus Nama comprises approximately 50 species native to arid regions of the New World, with a center of diversity encompassing the southwestern United States and north-central Mexico. The dataset for this study includes nuclear (ITS) and 4 kb of chloroplast DNA (matK and ndhF) for all but 3 species of Nama and several outgroup taxa. Molecular phylogenies inferred from parsimony, maximum likelihood, and Bayesian analyses of the nuclear and chloroplast data are generally congruent with each other and mostly consistent with previous morphologically-based infrageneric classifications. However, our data confirm that two species whose generic placements have historically been debated are in fact more closely related to members of the genus Eriodictyon than to Nama.
