The genus Hemerocallis (family Xanthorthoeaceae) is a herbaceous species, some of which are very important in herbal medicines. We evaluated the rps16-trnK region of the chloroplast DNA of a representative sample of eight taxa in Korea to estimate phylogenetic relationships within the taxa of this genus. Due to differences in the number of inserted nucleotides, the aligned data for Hemerocallis ranged from 729 (H. aurantiaca) to 742 nucleotides (H. fulva var. kwanso), with a mean of 736. Although several small indels and 20 inserts were present, sequence variation within the Hemerocallis genus was mostly due to nucleotide substitutions. All rps16-trnK trees generated in Korea exhibited a well-solved topology, with high bootstrap support, irrespective of the methods (parsimony) and the setting used. The node of H. minor and H. littorea was strongly supported, with a high bootstrap value in three trees, and these two taxa were sistered with H. thunbergii. The number of chromosomes was not congruent with that found in a previous study with RAPD, but the number was in agreement with the results of this study.
