"Systematics Natural Groups, and the Rapid Radiation of Neotropical Phlegmariurus (Lycopodiaceae)" with Wes Testo, University of Vermont.

Abstract: The tropical clubmoss genus Phlegmariurus is the most species-rich group in the Lycopodiaceae, with approximately 300 species. Approximately 150 species are known from the American tropics, with the northern Andes being a center of diversity. The group displays exceptional morphological and ecological diversity, and includes epiphytic, lithophytic, and terrestrial members. In this talk, I will discuss the evolutionary relationships of this group, redefine principal clades based on molecular and morphological evidence, and infer the timing and tempo of its diversification.
