Phylogenetic relationships among 8 species of Rhododendron were derived from sequence comparisons of the chloroplast trnF-trnL intergenic spacer region. Aligned sequences of the 8 Rhododendron taxa were 460 base pairs. The region contained 16 variable sites, of which 10 were phylogenetically informative. Neighbor-joining and parsimony analyses were conducted using MEGA. Identical topology with 3 major clades was obtained from parsimony and neighbor-joining trees. Clade 1 consisted of R. pseudochrysanthum, R. rubropunctatum, R. morii, R. hyperythrum, and R. formosanum. Rhododendron formosanum was sister to the other 4 species in the clade 1. Clade 2 consisted of R. oldhamii and R. kanehirai. Rhododendron ellipticum formed clade 3 and was basal to all other Rhododendron species. Close phylogenetic relationships among R. pseudochrysanthum, R. morii, R. rubropunctatum, and R. hyperythrum based on the cpDNA sequences agreed with those derived from morphological characters.
