Widely mat-forming, spreading by underground stolons and 15-30cm tall. Leaves dark green, leathery, oval, obovate or oblanceolate, either rounded or pointed at the tips, up to 2-3cm long, upper surfaces dark green, lower sides lighter. Flowers urn-shaped, 6mm long in axillary clusters, summer. Fruits 1cm in diameter, white, insipidly sweet. Western China on moist rocks in open woods. Related to G. itoana, its smallest leaved form closely resembling that species. The larger, oval-leaved form is nearer in appearance to G. miqueliana from which it can be distinguished by the wintergreen taste of its fruits.
