Résumé :	Based on a study of the morphology and stem anatomy of a broad sample of specimens attributed to Cytisus purgans auct. non Cytisus purgans (L.) Boiss. four species are recognized. Two species are non-spiny: Cytisus oromediterraneus Rivas Martínez et at. is a widely distributed taxon ranging from central France to north-central Spain and Portugal, and C. galianoi Talavera & Gibbs, sp. nov., which is restricted to schistose sierras in south-east Spain. C. oromediterraneus has 8-ribbed stems and 2-ribbed stipular organs, whilst C. galianoi has 10-ribbed stems and 3-ribbed stipular organs. Of two spiny species, Cytisus balansae (Boiss.) Ball wkh 10-ribbed stems, occurs in calcareous mountain areas, 1800–2500 m in Algeria and southern Morocco, whilst C. valdesii Talavera & Gibbs, nom. nov. with 13-ribbed stems, occurs in die High and Middle Atlas of Morocco.
