Species delimitation in the Castilleja pilosa species complex.

Castilleja pilosa is a species of perennial paintbrush native to the Pacific Northwest of the United States. This species can be identified by an inflorescence and floral morphology resembling those of Orthocarpus: a pale-green to yellow-green inflorescence with a large lower corolla lip, a short beak, and a sub-equally divided calyx. There are three named varieties that are currently recognized based on geographic and morphological differences; Castilleja pilosa var. pilosa has a longer calyx with fine curly hairs and can be found throughout southeast Oregon, northwest Nevada, and northeast California, Castilleja pilosa var. steenensis has a longer calyx with coarser spreading hairs and is endemic to the summit ridge of Steens Mountain, Oregon, and Castilleja pilosa var. longispica has a shorter calyx, retrorsely curved hairs, and is found throughout southeast Idaho, Wyoming, and Montana. The present study is focused on species delimitation in the Castilleja pilosa complex, including eight putatively closely related Castilleja species using molecular data from several independent nuclear gene regions and coalescent-based species tree and species delimitation analyses.
