Abstract

Dipelta (Caprifoliaceae) is endemic to China, and comprises 3-1 species. Here we used DNA sequences, and SSR and AFLP data to investigate relationships among these taxa. Cluster analysis of all the data showed that D. elegans, an endangered species, was early separated from the others. Both SSR and AFLP data indicated that individuals of D. wenxianensis and D.floribunda were mixed together, suggesting that they were conspecific. STRUCTURE analysis revealed the introgression between D. floribunda and D. yunnanensis, which might produce new "taxa" like D. wenxianensis.
