abstract = {Evolutionary relationships within the comparium Sedum series Rupestria (Crassulaceae) were investigated by phylogenetic analyses of restriction site variation of the chloroplast genome and morphological variation. DNAs were digested with 21 restriction enzymes and hybridized with S. album cpDNA probes covering the entire genome. A total of 141 ingroup variable restriction sites was identified. Morphological variation was observed in a total of 66 characters. Both datasets were analysed using parsimony methods and compared with evidence from cytology, artificial hybridization and biogeography to infer evolutionary relationships. The results 1) indicate a relatively high level of nucleotide sequence divergence within S. ser. Rupestria; 2) indicate three main lines of plastome differentiation, which are in agreement with morphology, basic chromosome numbers, and centres of diversity; 3) do not provide a compelling solution for basal relationships; 4) support an earlier hypothesis on reticulation and provide evidence for a third case of allopolyploidy in the series; 5) suggest that interspecific gene flow in S. ser. Rupestria is funnelled through the presumably allopolyploid S. rupestre subsp. erectum.}
