In this study, revision of taxa belonging to the genus Bolanthus (Ser.) Rchb. spreading in Turkey was done. All plant samples required for the revision work were collected from a number of addresses specified in the method and material section of the thesis. Also, the existing samples in Bozok University Biology department herbarium with Ankara ANK, HUB, GAZI, İstanbul ISTO, ISTF, ISTE, Van VANF, İzmir EGE and Konya KNYA herbariums was evaluated. On the other hand, type photos of the taxa were obtained from P (Paris), E (Edinburgh), K (Kew) and G (Geneva) herbariums located abroad and were examined. Common descriptions of the taxa belonging to the Bolanthus genus have been tried to be solved. For this reason, the characters such as the distance between leaf shapes and internodes, the structure of underarm bundles, pedicel length, type and frequency of flowering, petal shape, petal shape and sepal ratio, fruit shape and number of sepals, number of seeds were used. Taxonomic location changes have been made to the rules. In this study, the relationship of these taxa with nearby species, habit paintings, detailed descriptions and distributions are given.
