Angiosperm phylogeny: 17 genes, 640 taxa.

Premise Of The Study: Recent analyses employing up to five genes have provided numerous insights into angiosperm phylogeny, but many relationships have remained unresolved or poorly supported. In the hope of improving our understanding of angiosperm phylogeny, we expanded sampling of taxa and genes beyond previous analyses.

Methods: We conducted two primary analyses based on 640 species representing 330 families.
