(named by Kalm after Dr. "Gaulthier,” a physician in Quebec, whose name was really written, Gaultier). Ericaceae. This includes the Wintergreen and some other ornamental low aromatic plants with alternate, evergreen leaves., white, pink or scarlet, often fragrant flowers. in terminal or axillary racemes or solitary, and with decorative, berry-like red or blackish flower. G. procumbens is fully hardy North, while the other N. American species need protection during the winter; they are well adapted for borders of evergreen shrubberies as well as for rockeries, and in the suitable soil they are apt to form a handsome evergreen ground-cover.
Most of the foreign species can be grown only South or as greenhouse shrubs. Some have edible fruits, and an aromatic oil used in perfumery and medicine is obtained from G. procumbens and several Asiatic species. They grow best in sandy or peaty, somewhat moist soil and partly shaded situations.
