Onosma L., the largest genus of Boraginaceae, is represented by 105 species in Turkey with an endemism rate of 52%. Phytochemical studies indicate that Boraginaceae plants mainly comprise naphthoquinones with a wide range of biological activities including anticancer, antiinflammatory, wound healing, and antioxidant effects. However, few taxa of the genus Onosma have been investigated in detail for their bioactivities. Considering the high rate of endemism and an inadequate number of bioactivity screening studies in literature, we aimed to evaluate the cytotoxic effects and topoisomerase inhibitory activities of some Onosma species growing in southwestern Turkey. Here, we describe a comprehensive cytotoxic …

Anthemis ekicii (Asteraceae) is described and illustrated as a new species from Tuz Lake in Aksaray Province in Central Anatolia. The new species belongs to the section Anthemis, and it is closely related to A. pauciloba var. pauciloba, from which it differs in stem, leaves, and capitulum features. Diagnostic characters, description, detailed illustrations, ecology, IUCN conservation status, and pollen and seed morphology are presented in this study.
