Abstract
Even though the species-rich genus Ceropegia is convincingly characterized by its pitfall flowers, investigation of non-coding markers of cpDNA (trnT-L and trnL-F spacers, and the trnL intron) and nrDNA (ITS) has shown that Ceropegia is twice paraphyletic. The 36 analyzed Ceropegia taxa are scattered over a grade of seven clades. One clade is shared by some Ceropegia and all Brachystelma species investigated, making Ceropegia (without Brachystelma) paraphyletic. All endemic Madagascan Ceropegia taxa investigated and the East African C. robynsiana share a terminal, but in most analyses unresolved clade with the stapeliads. Thus, again, Ceropegia without the stapeliads, is paraphyletic. These results are incongruent with current taxonomy. In absence of adequate morphological, anatomical or karyological characters supporting a taxonomical reclassification of the genus in accordance to the retrieved clades of the phylogenetic analysis, it is proposed to classify Ceropegia as a morphogenus and to hold on to the current taxonomy.
