Systematics Mortimer, Sebastian [1], Tank, David [1]. Phylogeny and evolution of Lamourouxia (Orobanchaceae): patterns of diversification in a neotropical radiation. An extensive monograph based on the morphological characters of Lamourouxia (Orobanchaceae) hypothesized three lineages (taxonomic sections) within the genus, highly unequal species distributions, several endemic species, and two independent origins of hummingbird pollination. Lamourouxia displays a confusing, and sometimes taxonomically conflicting, array of floral and vegetative characters. We used various molecular approaches to elucidate evolutionary relationships between sympatric and allopatric taxa and to infer a species tree. Furthermore, we reconstructed the evolution of taxonomically informative characters of described species within the genus. With these inferences in mind, we restructure the taxonomy of the genus to reflect monophyletic groupings. This will inform further work concerning biogeography and the processes of diversification in the genus. Log in to add this item to your schedule
