The tribe Amorpheae is an early-branching monophyletic clade of the flowering plant subfamily Faboideae or Papilionaceae. It is found from Mexico to Argentina. It was recently included in an informal monophyletic clade known as the dalbergioids sensu lato. This tribe is consistently resolved as monophyletic in molecular phylogenetic analyses. It is estimated to have arisen 36.9 ± 3.0 million years ago (in the Eocene). A node-based definition for Amorpheae is: "the MRCA of Psorothamnus arborescens and Eysenhardtia orthocarpa." The tribe exhibits the following morphological synapomorphies: "epidermal glands throughout the plant body; dry, indehiscent fruits that are single-seeded; and terminal inflorescences."

Amorphoids

The amorphoids can be distinguished from the daleoids on the basis of their non-papilionaceous flowers.

  • Amorpha L.
  • Apoplanesia C. Presl
  • Errazurizia Phil.
  • Eysenhardtia Kunth
  • Parryella Torr. & A. Gray
  • Daleoids

    The daleoids can be distinguished from the amorphoids on the basis of their generally papilionaceous corollas.

  • Dalea L.
