The Genus Dichodon (Caryophyllaceae) in Turkey

Abstract

Dichodon (Bartl. ex Rchb.) Rchb. is a small genus and was formerly included in Cerastium. However, the first specimens of this genus were introduced to the literature as Stellaria. Dichodon, taxonomically, remains in between Cerastium and Stellaria genera. Although there are 16 identified species worldwide, the status of some of them is doubtful. There are three species identified so far in Turkey. In this study, the taxonomic status of the species belonging to the genus Dichodon is discussed. A species previously mentioned as a synonym has been validated. The distribution of all species in Turkey is shown on the maps and scientific Turkish names are suggested for the species. In addition, a new identification key was proposed for the first time and herbarium photographs of the species were added to the study.
