Phylogeny for Coccinia based on plastid DNA sequence data. Phylogenetic relationships in Coccinia based on 4,551 nucleotides of concatenated plastid DNA sequences obtained for 69 accessions and analyzed under maximum likelihood (ML) and the GTR + Γ model. Numbers below branches refer to ML bootstrap support > 75%. The dots at nodes and behind the two brackets refer to uniquely shared indels (Methods). The naming of the clades follows that in the nuclear tree (Figure 2). A single accession of C. sessilifolia in the nuclear tree groups with the C. quinqueloba clade, but the plastid data do not contain sufficient signal to resolve the placement of this species.
