Osmanthus armatus (Oleaceae) is mainly distributed in the southwest of China and also planted in arboretums as an ornamental plant. In the present study, the plastome of O. armatus was reconstructed using genome skimming sequencing, and the phylogeny analysis was inferred based on whole plastome data. The plastome of O. armatus is 155,259 bp in length, comprising two copies of inverted regions (IR, 25,680 bp) separated by the large single copy (LSC, 86,534 bp) and small single copy (SSC, 17,365 bp) regions. The genome encodes 114 unique genes, including 80 different protein-coding genes, 30 tRNA genes, and four rRNA genes, with 20 duplicated genes in the IR regions. Phylogenetic analysis suggests that the representative species from Osmanthus is monophyletic, and O. armatus is sister to O. fragrans within this genus.
