title: [Study on molecular evidence of revision of taxonomic placement of Peucedanum decursivum].
abstract: OBJECTIVE
  To explain the molecular evidence of revision of taxonomic placement of Peucedanum decursivum based on the nrDNA ITS sequence.
  
  
  METHODS
  PCR amplification, DNA sequencing and cladistic analysis.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  P. decursivum belongs to genus Angelica. The scientific name of P. decursivum should be revised as A. decursivum. A. decursivum and P. praeruptorum should be used as crude drug respectively.
