A new species of Dianthus (Caryophyllaceae) from Antalya, South Anatolia, Turkey

Dianthus multiflorus from Gazipasa (Antalya), south Anatolia (Turkey), is described as a new annual species with verrucose calyx. The morphological differences from the species within the same group with D. multiflorus, which are D. aydogdui, D. cyri and D. tripunctatus, are discussed. The International Union for Conservation of Nature (IUCN) threat category and observations on the ecology of the populations are noted. The karyology and seed micromorphology of D. multiflorus and D. tripunctatus were examined by light microscopy and scanning electron microscopy.
