  1. Note: (×2): gene with two copies; (×4): gene with four copies; *: gene containing one intron; **: gene containing two introns; : psbZ gene is only present in the chloroplast genomes of H. neocarneum and H. coccineum, respectively; : lhbA gene is missing in the chloroplast genomes of H. neocarneum and H. coccineum, respectively; : trnS-GCU and trnT-UGU exist two gene copies only in the chloroplast genome of G. schomburgkii, and only once in other 9 sequenced chloroplast genomes in this study; : trnS-GGA and trnT-GGU are missing in the chloroplast genome of G. schomburgkii
