The non-protein amino acid-accumulating clade, also known as the Canavanine-accumulating clade is a clade of the flowering plant subfamily Faboideae (or Papilionoideae) that includes the majority of agriculturally-cultivated legumes.

[3][4][1] It is characterized by the accumulation of the non-proteinogenic amino acid canavanine in the seeds—a deterrent against herbivory.

[5] This clade is consistently resolved in molecular phylogenies.

[3][4][2] It contains many economically important genera, including Cicer, Glycine, Medicago, Phaseolus, Trifolium, Vicia, and Vigna.

[2] 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.
