Abstract

Xerophyta retinervis has great ornamental value and numerous traditional uses. This study reported its first complete chloroplast genome sequence, which was 155,109 bp in length, including a pair of inverted repeat regions (IRs) (27,093 bp), a small single-copy (SSC) region (17,385 bp), and a large single-copy (LSC) region (83,538bp). The chloroplast genome encoded 133 genes, including 87 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. The total GC content of the chloroplast genome was 37.55%. The phylogenetic tree showed that X. retinervis was closely related to X. spekei.
