Southwestern Plant Families Arranged Phylogenetically


For the most part, I am following the Angiosperm Phylogeny Group III for family-level and higher taxonomy. The Angiosperm Phylogeny Website also follows APGIII (so far as I can tell) and provides all kinds of supplementary information. See this page for a brief list of families that have changed recently or might otherwise be confusing. I've added infrafamilial taxa for some particularly large or heterogenous families.
