Diversity, endemism and conservation of California monkeyflowers (Phrymaceae): a case study in Erythranthe section Paradantha.

Plants placed in the genus Mimulus L. (Phrymaceae), as traditionally defined, are commonly known as monkeyflowers. These charismatic plants are exceedingly diverse in western North America with over 150 of the nearly 200 species worldwide occurring here. Nearly 60% (ca. 100) of the species native to western North American occur in California. However, Mimulus has recently undergone significant changes in taxonomy leaving the name Mimulus virtually absent from the California flora. Two genera that have been resurrected; Erythranthe Spach and Diplacus Nutt., account for nearly all of the species diversity in western North American Phrymaceae. Erythranthe is the most diverse of the genera segregated from Mimulus s.l., with 120 species currently recognized. Erythranthe section Paradantha (Phrymaceae) has recently been a source of floristic novelty, with five new species described from California and Nevada. Erythranthe section Paradantha is a relatively species rich lineage within which species identification has been challenging resulting in disagreement among taxonomic authorities. In this study, I examine species boundaries and relationships in Erythranthe section Paradantha in a phylogenetic context using a dense sampling scheme that benefits from extensive fieldwork. Results of this study will inform a taxonomic revision that also incorporates evidence from morphology and ecology.
