Abstract
Crocus yaseminiae is described as a new species from Alanya province in South Anatolia. A short literature history of the closely related taxon Crocus isauricus Siehe ex Bowles (≡ Crocus biflorus subsp. isauricus (Siehe ex Bowles) Mathew) is given together with a lectotypification of its name, and a discussion of the type specimen and locus classicus. Diagnostic characters were discussed of the taxa belonging to the “isauricus group” (C. biflorus subsp. isauricus, C. roseoviolaceus, C. mersinensis, C. taseliensis, and C. karamanensis). Fenugreek scented flowers are reported for the first time for the genus.
