Abstract

The 26 taxa of genus Spiraea (Rosaceae) in 14 Korean taxa and four taxa of them doubled in the world itself were collected and investigated phylogenetic relationships within these taxa using the chloroplast trnL-trnF region. Sequence variation within the genus Spiraea was mostly due to insertion/deletion. Total alignment sequence of trnL-trnF region in genus Spiraea was 1004 positions, of which 126 were parsimony-informative, 149 variable, 23 singleton, and 847 constant characters. The base furtherance did not show a significant difference among total taxa. Although many taxa of genus Spiraea were well separated each other, many branches were not congruent with the taxon positions with botanical names. In addition, sequences of the chloroplast trnL-trnF region for same species are different from each other according to authors. The taxonomic identification of genus Spiraea are in need of revision.
