| Summary: | Bougainvillea spectabilis is an important ornamental plant in tropical and subtropical regions, whose complex and diverse germplasm has brought great difficulties to variety selection and identification. Here, to provide data support for the identification of the relationship between cultivars of B. spectabilis, we sequenced the chloroplast genome of B. spectabilis. The chloroplast genome is 154,520 bp in length, including a large single-copy (LSC) region of 88,101 bp and small single-copy (SSC) region of 17,729 bp, and a pair of invert repeats (IR) regions of 24,171 bp. The chloroplast genome contains 129 genes, including 83 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The phylogenetic analysis based on 14 chloroplast genome demonstrated a close relationship between B. spectabilis and other plant species in Caryophyllales. The chloroplast genome will help for further of taxonomy research and provide data support for the identification of genetic relationship among different cultivars of B. spectabilis.
