Discussion | Species ca. 115 (6 in the flora). Gaultheria is characterized by its fruit and by the stamens having flattened filaments and awned anthers. All of the species are woody to varying degrees; the growth form varies from erect or spreading shrubs to procumbent or creeping and mat-forming. Eastern Asia and the Andes mountains of South America are centers of diversity for this genus. In North America, the fruits and leaves of Gaultheria are a food source for wildlife, and native peoples have medicinal and food uses for some species. Oil of wintergreen (methyl salicylate) is found in the leaves and fruits of some species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
