Clematis austroanatolica (Ranunculaceae), an unusual new species from southern Anatolia, Turkey

Abstract

Clematis austroanatolica (Ranunculaceae) is illustrated and described as a new species endemic to southern Anatolia, Turkey. It is related to C. vitalba and differs from the latter in having leaves with narrowly ovate, dentate-serrate leaflets, trifoliolate lowermost pinnae as well as small, pale pink flowers with orange-brown filaments. A key to the Turkish taxa of Clematis is provided.
