Abstract
Abstract: In this paper Ceropegia reflexa Hanacek, belonging to Ceropegia sect. Rhytidocaulon, is described. It is known from one locality in the Al Mahra Governorate of Yemen in the southern part of the Arabian Peninsula. This new species is characterized by long pedicels, reflexed corolla lobes and the unusual twisted cilia along the margins of the lobes. Ceropegia reflexa occurs together with C. fulleri in rocky parts of Jabal Fartak, but at lower altitudes and in less exposed places than C. fulleri. A key to the nine Arabian members of Ceropegia sect. Rhytidocaulon is provided.
