Two New Species with Pendulous Fruits in Hesperis (Brassicaceae) from South Anatolia, Turkey

Two new species, Hesperis anatolica A. Duran and H. hamzaoglui A. Duran (Brassicaceae), are described and illustrated from Anatolia, Turkey. Hesperis anatolica grows in serpentine pebbly slopes and open pine forest and scrub in Pozanti and Karsanu (Adana province). It is closely related to H. persica Boissier, an endemic confined to South Anatoli. Hesperis hamzaoglui grows in granitie rocky sites in a forest-steppe ecotone from Zorkun Yayla (Osmaniye province). It is closely related to H. podocarpa Boissier, an endemic confined to the Amanos Mountains. Diagnostic morphological characters are discussed, as well as the ecology, biogeography, and conservation status of both new species . In additin, the pollen characteristics and seed coat surface of H. anatolica, H. persica, H. hamzaoglui, and H. podocarpa are examined by SEM. Hesperis anatolica is diploid with a new report of the chromosome number of 2n = 12.
