Sedum emarginatum Migo is a perennial herb endemic to China. Here, we assembled and characterized the complete chloroplast genome of S. emarginatum using Illumina sequencing data. Our assembled chloroplast genome is 149,188 base pairs (bp) in length, containing a large single-copy (LSC) region of 81,399 bp, a small single-copy (SSC) region of 16,721 bp, and two inverted repeat (IR) regions of 25,534 bp. In addition, the chloroplast genome possesses a total of 127 genes, including 82 proteincoding genes, eight rRNA genes, and 37 tRNA genes.

Richness-Environment Relationships for Saxifraga L. richness patterns in China, especially for alpine plant groups. The negative association of species richness with temperature suggests a potential threat of alpine biodiversity loss in HHM from future warming.
