The tribe Amorpheae is an early-branching clade within the flowering plant subfamily Faboideae or Papilionaceae. It is found from Mexico to Argentina. [2] It was recently found to belong in a larger clade known informally as the dalbergioids sensu lato. [2] [3] [4] This tribe is consistently resolved as monophyletic in molecular phylogenetic analyses. [2] [3] [4] [1] [5] [6] [7] [8] [9] [10] It is estimated to have arisen 36.9 ± 3.0 million years ago (in the Eocene). [6] A node-based definition for Amorpheae is: "the MRCA of Psorothamnus arborescens and Eysenhardtia orthocarpa ." [6] The tribe exhibits the following morphological synapomorphies: "epidermal glands throughout the plant body; dry, indehiscent fruits that are single-seeded; and terminal inflorescences." [1]

Amorphoids

The amorphoids can be distinguished from the daleoids on the basis of their non-papilionaceous flowers. [1]

Daleoids

The daleoids can be distinguished from the amorphoids on the basis of their generally papilionaceous corollas. [1]
