Sequencing and characterization of the chloroplast genome of Stapf provide insights into phylogenetics in .

Stapf is an essential traditional Chinese medicine, and is beneficial in dispelling wind, removing dampness, warming, and relieving pain. However, its phylogenetic position of is not accepted yet. In order to clarify the evolutionary relationship of , complete sequencing of chloroplast genome was carried out using Illumina sequencing technology. In total, the chloroplast genome was about 155,869 base pair (bp) in length and carried a typical tetrad structure that included a large single-copy, a small-single copy and two inverted repeat regions. A total of 132 genes were annotated, that included 85 protein -coding genes, 37 transfer RNA genes, eight ribosomal RNA genes, and two pseudogenes. The phylogenetic tree analysis indicated that is closely related to and
