The complete chloroplast genome sequence of <i>Didymocarpus yuenlingensis</i> W. T. Wang 1982

<i>Didymocarpus yuenlingensis</i>, a perennial plant in <i>Gesneriaceae</i>, is mainly found in Hunan, China, growing on stone cliffs. Its classification was traditionally based on morphology, lacking genetic data. This study sequenced its chloroplast genome (153,932 bp, GC 37.55%) and identified 133 genes, including 88 protein-coding genes. Phylogenetic analysis revealed its close relationship with <i>D. sinoprimulinus</i> and <i>D. heucherifolius</i> var. <i>yinzhengii</i>. These findings provide valuable genetic resources for understanding its evolutionary relationships and supporting future research on the <i>Didymocarpus genus</i>.
