The Cladrastis clade is a monophyletic clade of the flowering plant subfamily Faboideae (or Papilionaceae) that is found in eastern Asia and southern North America.[2][3][4] It is consistently resolved in molecular phylogenies and is sister to the Meso-Papilionoideae.[1][3][4][5][6][7][8][9][10] Evidence for the existence of this clade was first proposed based on morphological (floral), cytological, and biochemical evidence.[11][12] It is predicted to have diverged from the other legume lineages 47.4±2.6 million years ago (in the Eocene).[13]

Description edit

This clade is composed of three genera: Cladrastis, the monotypic Pickeringia, and Styphnolobium.[8] Fossils of species of Cladrastis and Styphnolobium have been discovered.[14] The name of this clade is informal and is not assumed to have any particular taxonomic rank like the names authorized by the ICBN or the ICPN.[2] The clade is defined as:

"The most inclusive crown clade containing Cladrastis kentukea (Dum. Cours.) Rudd 1971 but not Dermatophyllum secundiflorum (Ortega) Gandhi & Reveal 2011 or Swartzia simplex Spreng. 1825."[2]
