A cladistic analysis of tribes Cicereae, Trifolieae, and Vicieae was carried out using 33 morphological, anatomical, karyological, and chemotaxonomical characteristics. Transformation polarities of the character states were developed by comparison with the character states of the genus Galega, the sister group of the tribes. Cicereae and Vicieae were found to be a monophyletic group, and Trifolieae was its sister group. The seven synapomorphic characters of Cicereae and Vicieae were presumed to be: germination hypogeal vs. epigeal; first leaf in seedlings scarious vs. laminous; leaves paripinnately and tendrilous vs. imparipinnately and etendrilous; postchalazal vascular bundle present in seed coats vs. absent; a cotyledon flap present at antihilar side vs. absent; radicles short in seeds vs. long; and plumules long in seeds vs. short.
