Amorpheae

The tribe Amorpheae is an early-branching clade within the flowering plant subfamily Faboideae or Papilionaceae. It is found from Mexico to Argentina. It was recently found to belong in a larger clade known informally 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.
 * Marina Liebm.
 * Psorothamnus Rydb.
