Summary:Crossostephium chinense is a common traditional Chinese medicinal plant used to cure arthralgia and rheumatism. The previous studies mainly focussed on its chemical compositions, with the genetic background and resources remaining scarce. Here, we conducted genome skimming for C. chinense, and using these data we not only assembled its complete chloroplast genome, but also reconstructed the phylogenetic relationship between C. chinense and Artemisia. The cp genomes of two C. chinense individuals ranged from 151,024 bp to 151,097 bp in length and had a typical quadripartite structure with a conserved genome arrangement. The cp genome encodes 114 unique genes, consisting of 80 protein-coding genes, 30 tRNA genes, and four rRNA genes, with 19 duplicated genes in the IR regions. Phylogenetic analysis indicates that C. chinense is sister to Artemisia annua and Artemisia fukudo.
