## Abstract

Lilium saccatum is a species of ornamental plant found in southeastern Xizang, China. In the present study, the complete chloroplast (cp) genome of L. saccatum was sequenced using next-generation sequencing (NGS). The de novo assembled cp genome was 151,839 bp in length, including a pair of inverted repeat regions (IRs; 26,421 bp), a small single-copy region (SSC; 17,528 bp), and a large single-copy region (LSC; 81,469 bp). The cp genome encodes 113 unique genes, including 79 protein-coding genes (PCGs), 30 tRNA genes, and four rRNA genes. The total GC content of the cp genome was 37.0%. Phylogenetic analysis of 24 cp genomes revealed that L. saccatum was closely related to L. souliei. This study could provide fundamental information for the phylogenomics and utilization of Lilium.
