Fruit morphology of sections of the genus Onobrychis Miller (Fabaceae) andits phylogenetic implications

Ln this study, fruit morphology of sections of the genus Onobrychis were ex amined. Fruit morphology origin, taxonomic position, and phylogeny of the g enus are discussed. The hypothesis obtained from a phylogenetic analysis ba sed on fruit morphology suggests the polyphyly of the genus excluding secti on Dendrobrychis. However, the result supports monophyly of four generic se ctions, Hymenobrychis + (Heliobrychis + (Lophobrychis + Onobrychis)).
