Characteristic of the complete chloroplast genome of , an important ornamental plant endemic to China.

is an important ornamental plant in China. Due to the lack of efficient molecular markers, although recent studies supported that was phylogenetically closely related to , , , and , relationships among these taxa remained uncertain. To examine the phylogenetic position of within Caprifoliaceae, we characterized the complete chloroplast (cp) genome of . The results showed that shared a typical quadripartite structure as with most angiosperms. It was 155,738 bp in length, including two inverted repeat (IR) regions (24,010 bp), a small single-copy (SSC) region (18,942 bp) and a large single-copy (LSC) region (88,776 bp). Phylogenetic analysis demonstrated that Caprifoliaceae and Adoxaceae formed two distinct monophyletic clades, and was closely related to and , albeit with low support. The whole cp genome of will be useful resources for future studies on phylogeny and conservation in
