Polygonatum zanlanscianense Pamp. is a plant species of the genus Polygonatum (Asparagaceae) distributed widely in China. The complete chloroplast genome of P. zanlanscianense was sequenced by Illumina sequencing technology. The plastome is 155,609 bp in length with a typical quadripartite structure, including one small single copy (SSC, 18,427 bp), one large copy (LSC, 84,438 bp), and two inverted repeat regions (IRs, 26,372 bp each). The cp genome encoded 132 genes, including 38 tRNA, 8 rRNA, and 86 protein-coding genes. The overall GC content is 37.7%. The ML phylogenetic analysis based on the cp genomes indicated that the genus Polygonatum is sister to the genus Heteropolygonatum within the tribe Polygonateae, P. zanlanscianense is sister to P. cirrhifolium within the genus Polygonatum. This study provides an important theoretical foundation for varieties identification, the phylogenetic relationship of P. zanlanscianense. Furthermore, this article takes a radical reform of Polygonati rhizoma.
