Eurycorymbus cavaleriei: is the only species of the genus Eurycorymbus and a Tertiary relict species endemic to China. The complete chloroplast (cp) genome sequence of this species is reported here. The total length of the circular genome was 158,777 bp, and the overall GC content was 37.9%. It consists of a large single copy region (86,940 bp), a small single copy region (17,991 bp), and two copies of inverted repeat regions (26,923 bp). The genome encoded a total of 137 genes, including 89 protein-coding genes, 40 tRNA genes and 8 rRNA genes. Among 137 genes, 18 contain one or two introns. The phylogenetic tree reconstructed from the known cp genomes of 12 Sapindaceae revealed that E. cavaleriei had the closest relationship with Dodonaea viscosa. The study laid the foundation for further research on the genome information and protection of this endangered plant.
