Otth were studied. The Silene specimens used in the study were collected from different localities between 2005 and 2007. Their conservation status, phytogeographical regions, and distribution in Turkey were determined. Detailed drawings of the general view and flower from each species were added to the study. As a result of these detailed investigations, the conditions of some species having taxonomic problems were re-examined, and suggestions were proposed. The results produced 3 taxa that are new to science and 2 taxa that are new records for the flora of Turkey. In addition, 5 species that were published as new species from Turkey were reduced to synonyms. Key words: Turkey, revision, Silene, systematic 1. Introduction Because of its geographical location, climate, and topographical and geological structure, Turkey’s rich flora is one of the most significant in the world. The main research into the flora of Turkey is Flora of Turkey and the East Aegean Islands, which was published from 1965 to 1988 and in 2000. There are 135 taxa belonging to Silene L. in 31 sections in Flora of Turkey; this has increased to 165 with the addition of new .
