description The plant “False Lily of the Valley”, <i>Speirantha gardenii</i> is restricted to south-east China and considered as an endemic plant. Due to its limited availability, this plant was less studied. Hence, this study is focused on its molecular studies, where we have sequenced the complete chloroplast genome of <i>S. gardenii</i> and this is the first report on the chloroplast genome sequence of <i>Speirantha</i>. The complete <i>S. gardenii</i> chloroplast genome is of 156,869 bp in length with 37.6% GC, which included a pair of inverted repeats (IRs) each of 26,437 bp that separated a large single-copy (LSC) region of 85,368 bp and a small single-copy (SSC) region of 18,627 bp. The chloroplast genome comprises 81 protein-coding genes, 30 tRNA and four rRNA unique genes. Furthermore, a total of 699 repeats and 805 simple-sequence repeats (SSRs) markers are identified in the genome. Additionally, K<sub>A</sub>/K<sub>S</sub> nucleotide substitution analysis showed that seven protein-coding genes have highly diverged and identified nine amino acid sites under potentially positive selection in these genes. Phylogenetic analyses suggest that <i>S</i>. <i>gardenii</i> species has a closer genetic relationship to the <i>Reineckea</i>, <i>Rohdea</i> and <i>Convallaria</i> genera. The present study will provide insights into developing a lineage-specific marker for genetic diversity and gene evolution studies in the Nolinoideae taxa.
