New combinations and new and resurrected names in Gaultheria (Ericaceae)

Abstract

The Wintergreen Group clade of the tribe Gaultherieae (Ericaceae: subfam. Vaccinioideae) comprises the genera Diplycosia Blume, Gaultheria L., and Tepuia Camp. Phylogenetic analysis has demonstrated that Gaultheria is not monophyletic, with Diplycosia and Tepuia nested within it. On morphological grounds, the recognition of a single genus in the Wintergreen Group to establish monophyly as the basis for the classification is favoured over subdivision into smaller genera. Here, we make the taxonomic changes necessary for recognising Gaultheria as the sole genus constituting the Wintergreen Group. We make 126 new combinations, erect 17 new names, and resurrect four species names in Gaultheria for all species, varieties, and forms heretofore recognised in the literature under Diplycosia or Tepuia. Additionally we make two new combinations in Gaultheria at the sectional level to accommodate the species from Diplycosia and Tepuia, and provide lectotypes for Pernettyopsis King & Gamble and Gaultheria [unranked] Amphicalyx Endl.

Patterns of genetic variation and morphology support the recognition of five species in the Gaultheria leucocarpa Blume (Ericaceae) group from mainland China

“…The best phylogenetic tree of Gaultheria from ML recovered a topology in which the samples of G. leucocarpa form a monophyletic group (BP = 100%, Figure S1, Appendix S5). This group is sister to the Diplycosia clade (see Kron et al, 2020). Phylogenetic relationships among most populations were resolved with bootstrap support greater than 80%.…”

Plastome characteristics and species identification of Chinese medicinal wintergreens (Gaultheria, Ericaceae)

“…Gaultheria Kalm ex L. (Ericaceae), containing approximately 288 species, are widespread throughout continental areas and islands bordering the Pacific Rim ( Lu et al., 2019b ; Kron et al., 2020 ). Some Gaultheria species are commonly called wintergreens because they produce wintergreen oil (methyl salicylate), which is widely used in drugs, pesticides, cosmetics, and foods ( Nikolić et al., 2013 ; Aruna et al., 2014 ; Luo et al., 2018 ).…”
