Aristolochia altanii (Aristolochiaceae), a new species from Turkey

Abstract

Aristolochia altanii Ilcim & Behcet sp. nov. is described from Turkey and illustrated. The specimens were collected from Kahramanmaras in South Anatolia. The new species is closely related to A. guichardii and A. brevilabris. However, this species differs in some important characteristics, such as the length of the pedicel and the perianth, the indument of the perianth limb, and the micromorphology of the pollen and the seeds. The diagnostic characters are discussed and taxonomic comments are presented.
