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]
Subclades and genera
Amorphoids
The amorphoids can be distinguished from the daleoids on the basis of their non-papilionaceous flowers.[1]
- 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.[1]
- Dalea L.
- Marina Liebm.
- Psorothamnus Rydb.
