The family Fabaceae is one of the most ecologically successful and diverse plant families in the world, especially in arid and subtropical regions. In this episode we talk Legumes - their ecology, floral morphology and evolution - with Marty Wojciechowski at ASU. We talk about the 50kb inversion, psychoactive and poisonous secondary chemistry, subfamily classifications elucidated by molecular phylogenetics, how mimosoids lack Rhizobium root affiliations (bummer) and a bunch more interesting sh#t. Plant in the thumbnail photo is Schotia afra.
