Shelley McMahon

My research in plant systematics has focused on papilionoid legumes, particularly in the Amorpheae, a group of c. 240 New World arid/semi-arid species, which includes Dalea, Marina, Psorothamnus, and Amorpha. My interests include the evolution of variation in floral morphology among lineages, their developmental morphology, and who is related to whom. I am also interested in general systematics of legumes and angiosperms, phylogenetic methodology, and large-scale phylogenetics and tree-of-life efforts.
