About 40 species, most diverse in the Mediterranean and southwestern Asia. The most comprehensive monograph dates from 1910 (Simmler 1910), with Shults (1989) providing an updated account for Russian taxa. Up to now, sampling has been minimal and offers no information on how related genera (Cyathophylla, Pleioneura, Bolbosaponaria, etc.) may best be treated.
