Cadia is a genus of flowering plants in the family Fabaceae which belongs to the subfamily Faboideae. It includes 8 species native to northeastern Africa, the Arabian Peninsula, and Madagascar. [1]

Unlike most plants in the Faboideae, it has radially symmetrical flowers. In related species with bilateral symmetry, such as those of Lupinus , the dorsal (upper or adaxial) part of the flower expresses one or more genes in the Cycloidea (CYC)/Dichotoma (DICH) family. In Cadia, these genes are expressed throughout the flower. Thus, from a molecular point of view, Cadia is not reversing the ancestral evolution from radial symmetry to bilateral symmetry but obtaining radial symmetry from a new mechanism. [4]

Eight species are accepted: [1]
