Elsholtzia rugulosa is a medicinal plant commonly used in southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of E. rugulosa to investigate its phylogenetic relationship in the family Labiatae. The chloroplast genome of E. rugulosa was 151,952 bp in length with 37.9% overall GC content, including a large single copy (LSC) region of 83,056 bp, a small single copy (SSC) region of 17,526 bp, and a pair of inverted repeats (IRs) of 25,685 bp. The cp genome contained 113 genes, including 80 protein-coding genes, 29 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated Elsholtzia was closely related to Perilla.

Ajuga forrestii is a medicinal plant commonly used in southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of A. forrestii to investigate its phylogenetic relationship in the family Lamiaceae. The chloroplast genome of A. forrestii was 150,492 bp in length with 38.3% overall GC content, including a large single copy (LSC) region of 82,148 bp, a small single copy (SSC) region of 17,160 bp and a pair of inverted repeats (IRs) of 25,592 bp. The cp genome contained 112 genes, including 79 protein coding genes, 29 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated Ajuga was closely related to Scutellaria. ARTICLE HISTORY

Salvia yunnanensis is a medicinal plant commonly used in the southwest of China. In this study, we sequenced the complete chloroplast (cp) genome sequence of S. yunnanensis to investigate its phylogenetic relationship in the family Lamiaceae. The total length of the cp genome was 151,338 bp, with 38.0% overall GC content and exhibited typical quadripartite structure, a pair of IRs (inverted repeats) of 25,578 bp each were separated by a small single-copy (SSC) region of 17,564 bp and a large singlecopy (LSC) region of 82,618 bp. The cp genome contained 114 genes, including 80 protein coding genes, 30 tRNA genes, and 4 rRNA genes. The phylogenetic analysis indicated S. yunnanensis was closely related to S. miltiorrhiza, which afforded a scientific evidence that S. yunnanensis could be used as original species of Radix et Rhizoma Saliviae Miltiorrhizae (Danshen).
