Phylogenetic relationship of Hudsonia (Cistaceae): a North American endemic genus.

Cistaceae are a small family of plants, most of which are shrubs occurring in nutrient-poor, sunny habitats principally in Eurasia and North America. Previously published phylogenetic work based on the analysis of plastid rbcL and trnL-trnF sequences has shown Hudsonia embedded in another genus – Crocanthemum, but with poor statistical support and little taxon sampling and thus low confidence. We sampled additional species of Hudsonia with several samples per species to test its phylogenetic placement within Cistaceae. Our data indicate that Hudsonia is sister to Crocanthemum. Given these results, its morphological distinctiveness, and the desire to create stable classifications, we suggest that the genus Hudsonia should be recognized. These results underscore the importance of objective means of developing evolutionary hypotheses in order to support stable classifications.
