Limonium gueneri Dogan, Duman & Akaydın sp. nova (Plumbaginaceae) is described and illustrated from Patara (C2 Antalya, Turkey), where it grows on calcareous slopes on the coast. It is probably closely related to L. ocymifolium (Poir.) Kuntze, an East Mediterranean species. The diagnostic morphological characters are discussed. A taxonomic key for the coastline species of Turkish Limonium without sterile branches is also presented along with some notes on the ecology and biogeography of the new species.
