The standard gene number in Hoya is 143, 113–114 genes were unique, and 17 genes were duplicated in the two IRs (Table 1). ycf15 gene is missing in three of the Dischidia species and ten species of Hoya. All chloroplast genomes include 79–80 protein-coding genes, 30 tRNA genes, and four rRNAs; the IR regions comprise 29 genes (17 protein-coding, 8 tRNA, and 4 rRNA genes).
