It bears a very close relationship with Ononis crispa, an endemism of Menorca and Cabrera, this latter has divided sepals and the flowers are piled up in a compact inflorescence at the top of the stems. It is also very close to Ononis natrix subsp. hispanica, which has smaller, less rigid leaves than this one. It flowers from spring to summer.
