Odontarrhena chondrogyna

Odontarrhena chondrogyna is a species of perennial flowering plants in the family Brassicaceae. It was previously included in the genus Alyssum, and hence named Alyssum chondrogynum, but was assigned to the newly established Odontarrhena after molecular phylogeny studies from the 2010s. It is endemic to the island of Cyprus, where it grows on rocky serpentinised slopes.
