Molecular analyses using ITS of nrDNA and trnSG intron of cpDNA were conducted to test the phylogenetic distinction between Taiwanese endemic Rhynchotechum brevipedunculatum and R. discolor widespread in subtropical and tropical Asia. The analyses revealed the reciprocal monophyly of the two species. This result indicates that R. brevipedunculatum is an independent species from R. discolor, adding molecular support for the taxonomic concept based on morphology.
