ABSTRACT

<p><b>OBJECTIVE</b>To explain the molecular evidence of revision of taxonomic placement of Peucedanum decursivum based on the nrDNA ITS sequence.</p><p><b>METHOD</b>PCR amplification, DNA sequencing and cladistic analysis.</p><p><b>RESULT</b>The ITS sequences and phylogenetic tree of 5 species of Angelica were and Peucedanum were acquired, in which 5 species were divided into 2 groups, Angelica group and Peucedanum group. P. decursivum was placed in the Angelica group.</p><p><b>CONCLUSION</b>P. decursivum belongs to genus Angelica. The scientific name of P. decursivum should be revised as A. decursivum.
