Phylogenetic Evaluation of Series Delimitations in Section Palmata (Acer, Aceroideae, Sapindaceae) Based on Sequences of Nuclear and Chloroplast Genes
Acer section Palmata (Japanese maples) is the largest section within the genus; however, series delimitations within section Palmata have not been evaluated in a phylogenetic context. Both maximum parsimony and maximum likelihood analyses of DNA sequence data of nuclear rDNA ITS and chloroplast genes (ndhF, trnL-trnF, and psbA-trnH) from 23 species of Acer section Palmata show that traditional series do not form individual clades. Results from this study support the most recent taxonomic treatment of Acer that does not recognize any series in section Palmata. Nuclear and chloroplast phylogenies are significantly incongruent, indicating that hybridization and introgression may be an important factor in the evolutionary history of section Palmata.
