Slender Wintergreen - Gaultheria ovatifolia
Slender wintergreen is a low shrub with slender, nearly prostrate, hairy stems, 5-20 cm (2-8 in) long. The alternate, mostly glabrous leaves, 2-4 cm (ca. 1 in) long, are egg-shaped with finely toothed margins. Single stalked flowers occur in the leaf axils. Each white flower, 3-5 mm long, has a 5-lobed, urn-shaped corolla and a shorter, brown-hairy, 5-lobed calyx. The fruit is a bright red, globose berry, 6-8 mm wide.
Mature fruit in August.
