Abstract :Quillworts or Çim Eğreltisi, species of the genus Isoetes L. in Turkey and the Levant, are poorly studied despite extensive floristic studies in the region. The Flora of Turkey lists 4 taxa: Isoetes olympica A.Braun insert ignore into journalissuearticles values(2n = 22);, I. histrix Bory var. histrix insert ignore into journalissuearticles values(2n = 20);, I. subinermis insert ignore into journalissuearticles values(Bory); Cesca & Peruzzi [=I. histrix Bory var. subinermis Durieu insert ignore into journalissuearticles values(2n = 22);] and I. duriei Bory insert ignore into journalissuearticles values(2n = ca. 121);. An additional species, I. anatolica Prada & Rolleri, was described in 2005 from Bolu province, and we report the first count for this species, 2n = 22. In Syria and Lebanon 2 species are known: I. olympica from a site in Syria and a known but undescribed plant from Akkar province insert ignore into journalissuearticles values(Lebanon); and adjacent Syria insert ignore into journalissuearticles values(2n = 22, first count);. A preliminary molecular phylogeny for these species is presented; their distribution and cytology are discussed. The taxonomy and nomenclature of the I. histrix and I. duriei groups need considerable further study. The first hybrids for the region are documented.
