The Leguminosae possess two basic seed types, a generalized form characteristic of the Mimosoideae and Caesalpinioideae, and a derived type characteristic of the Papilionoideae. Intermediates between caesalpinioid and papilionoid seeds strengthen the hypothesis that the phyletic roots of the Papilionoideae are in the Caesalpinioideae. Seed data affirm a relationship between the Mimosoideae and Caesalpinioideae but provide little new information as to the nature of this kinship. The Mimosoideae are not closely related to the Papilionoideae on the basis of seeds or other features.
