This genus was placed in either Dipsacaceae or Valerianaceae or in a family of its own, Triplostegiaceae. In this paper, the chloro- plast DNA (cpDNA) trn L-F regions of 21 species in the Dipsacales s. l. (including Valerianaceae, Dipsacaceae, Triplostegia, Morina, Caprifoliaceae s. l. and Adoxaceae) and an outgroup Panax schin-seng Nees. were amplified and sequenced. The phylogenetic relationships among these 22 spe- cies were constructed based on trn L-F sequences. The results demonstrated that Valerianaceae, Dipsacaceae, Triplostegia, Morina and four genera from the Caprifoliaceae s. l. form a monophylet- ic group with a strong support (100% bootstrap). Triplostegia, a sister group to Dipsacaceae, is close enough to be placed in the Dipsacaceae as a subfamily. The traditional Caprifoliaceae s.l. are polyphyletic, and relationships of Morina among the groups within Dipsacales s. l. are uncertain.
