Abstract
Dichoropetalum vuralii, a new species of Dichoropetalum sect. Dichoropetalum, is described and illustrated from the alpine stage of Dedegöl Mountains in south-western Anatolia, Turkey. It is morphologically similar to D. depauperatum and D. bupleuroides from which it differs mainly in the stem length, basal leaves and segments, number and shape of bracts and bracteoles, and mericarp features. The diagnostic morphological and carpo-anatomical characters of D. vuralii are discussed with regard to other close relatives. Additionally, notes are presented regarding its ecology and conservation status. Furthermore, pollen and mericarp surface characteristics are investigated using light microscopy (LM) and scanning electron microscopy (SEM). The geographical distribution of this new species, as well as related species, is mapped.
