AbstractChrysoglossum ornatum Blume, the type species of Chrysoglossum Blume, belongs to the tribe Collabieae of the subfamily Epidendroideae of Orchidaceae. In this study, we sequenced, assembled, and analyzed the complete chloroplast genome of C. ornatum. The result showed that the complete chloroplast genome of C. ornatum was 158,175 bp in size, consisting of a large single-copy (LSC) region of 87,235 bp, a small single-copy (SSC) region of 18,384 bp, and a pair of inverted repeats (IRs) of 26,278 bp. The chloroplast genome encoded 113 unique genes, comprising 80 protein-coding genes, 29 tRNA genes, and four rRNA genes. Phylogenetic analysis inferred from the complete chloroplast genome indicated that Chrysoglossum was closely related to Collabium Blume. This study provides genomic resources helpful for further phylogenetic and biodiversity research on Chrysoglossum.
