Gaultheria griffithiana is an evergreen shrub in the family Ericaceae. It is used as a source of the Chinese traditional medicine, Tougucao, with distribution of the junction of eastern Himalaya and Hengduan Mountain. The chloroplast genome of G. griffithiana is 175,649 bp in length with 135 genes, including eight rRNA genes, 39 tRNA genes, and 85 protein-coding genes. Phylogenetic analysis has converged on the placement of G. griffithiana as sister to G. praticola, G. nummularioides, and G. hookeri within the Leucothoides clade of Gaultheria in this study.

Gaultheria fragrantissima (Ericaceae) is an aromatic medicinal plant with high concentrations of the secondarymetabolite methyl salicylate (oil of wintergreen). In this study, the complete chloroplast genomeof G. fragrantissima was sequenced. The complete plastome is 176,196 bp in length, and the GCcontent is 36.6%. The plastome comprises 110 unique genes (76 protein-coding, 30 tRNA and 4 rRNA).Phylogenetic analysis fully supported a sister relationship between G. fragrantissima and G. hookeriwithin the Leucothoides clade of Gaultheria. This chloroplast genome will serve as a valuable referencefor future taxonomic and phylogenetic research.

Gaultheria leucocarpa Blume (also referred to herein as the "G. leucocarpa group") belongs to the Gymnobotrys clade of the genus
