A Phylogenetic Classification Of Polemoniaceae, J. Mark Porter, Leigh A. Johnson
Aliso: A Journal of Systematic and Floristic Botany
Three hundred seventy nine species of Polemoniaceae are arranged in a phylogenetic classification composed of three subfamilies, eight tribes, and 26 genera. Nomenclature of one tribe is clarified and the circumscription of several tribes differs greatly from previous classifications. Five new genera, Bryantiella, Dayia, Lathrocasis, Microgilia, and Saltugilia, are proposed. In addition, four new species are described from the genera Allophyllum, Dayia, Giliastrum, and lpomopsis. This treatment represents a major reclassification with 59 new combinations, and the application of several additional combinations not used in recent years.
