Acanthochlamys  P.C. Kao is a Chinese endemic monotypic genus, whereas  Xerophyta   Juss . is a genus endemic to Africa mainland, Arabian Peninsula and Madagascar with ca.70 species. In this recent study, the complete chloroplast genome of  Acanthochlamys bracteata  was sequenced and its genome structure compared with two African  Xerophyta  species ( Xerophyta spekei  and  Xerophyta viscosa ) present in the NCBI database. The genomes showed a quadripartite structure with their sizes ranging from 153,843 bp to 155,498 bp, having large single-copy (LSC) and small single-copy (SSC) regions divided by a pair of inverted repeats (IR regions). The total number of genes found in  A. bracteata ,  X. spekei  and  X. viscosa  cp genomes are 129, 130, and 132, respectively. About 50, 29, 28 palindromic, forward and reverse repeats and 90, 59, 53 simple sequence repeats (SSRs) were found in the  A. bracteata ,  X. spekei , and  X. viscosa  cp genome, respectively. Nucleotide diversity analysis in all species was 0.03501, Ka/Ks ratio average score was calculated to be 0.26, and intergeneric K2P value within the Order Pandanales was averaged to be 0.0831. Genomic characterization was undertaken by comparing the genomes of the three species of Velloziaceae and it revealed that the coding regions were more conserved than the non-coding regions. However, key variations were noted mostly at the junctions of IRs/SSC regions. Phylogenetic analysis suggests that  A. bracteata  species has a closer genetic relationship to the genus  Xerophyta . The present study reveals the complete chloroplast genome of  A. bracteata  and gives a genomic comparative analysis with the African species of  Xerophyta . Thus, can be useful in developing DNA markers for use in the study of genetic variabilities and evolutionary studies in Velloziaceae.
