Polygala L. comprises about 720 species (400 American, 206 African, 32 European, 70 Asiatic and 12 Australian).The genus is extended all over the world except Polynesia. New Zealand and the polar regions. The 24 Western Mediterranean species of Polygala belong to three subgenera (5 to the subgen. Chamaebuxus, 1 to the subgen. Brachytropis and 18 to the subgen. Polygala). Looking into morphological, caryological, Palynological, anatomical and ontogenic data, subgenus Chamaebuxus looks more primitive than subgenus Polygala, and subgenus Brachytropis is perhaps derived from the former.
