Camellia rubituberculata Chang ex Lin et Lu is an endemic woody plant species with ornamental and edible oil value in Guizhou, China. Lack of genetic information seriously hinders its conservation and sustainable utilization. In this study, its complete chloroplast genome was assembled and annotated. Results show that the total length of the genome is 157,137 bp, in which the LSC is 86,782 bp in length, the SSC is 18,279 bp, and the length of the two long repeat regions is 26,038 bp, respectively. A total of 115 genes in the chloroplast genome of C. rubituberculata were annotated, including 80 protein-coding genes, 29 tRNA genes and 4 rRNA genes. In addition, there are 19 genes with two copies in the genome. Phylogenetic tree based on 62 homologous coding genes from 24 species chloroplast genomes showed that C. anlungensis is the most closely related species of C. rubituberculata. These results could enrich the chloroplast genomic information of Theaceae species, and lay a solid foundation for the study of phylogenetic relationships of this family, as well as the conservation and sustainable utilization of C. rubituberculata.
