Ericaceae: Systematics, Ecology and Evolution

Jolles, Diana [1].

Biogeography and taxonomy of the North American prince's pine, genus Chimaphila (Pyroleae; Ericaceae).

The genus Chimaphila Pursh (prince’s pine) is currently recognized as five species, three of which occur in North and Central America. Past taxonomic treatments of New World Chimaphila have recognized a far greater number of species and subspecies based on a variety of morphological characters and geographic isolation. With the current preliminary study, molecular markers were used to assess the extent to which multiple disjunct species should be recognized, with special emphases on both (a) Rydberg’s 1914 treatment for the North American Flora published by the New York Botanical Garden, and (b) Chimaphila maculata L., a species found in eastern North America and several areas of Mexico. With this talk, the morphological characteristics Rydberg used to circumscribe taxa, especially in Mexico, are explained and evaluated in light of new genetic evidence and well-established patterns of geographic isolation. Finally, the potential of montane regions in southern North America and Central America to harbor genetic diversity for largely North Temperate lineages is revisited.
