Also known as alpine wintergreen, matted wintergreen is a low, matted shrublet with branched trailing stems up to 20 cm long and erect, leafy stems up to 3 cm high. The stems and leaves are mostly glabrous, although some reddish hairs may be found on the stems. The leaves have short petioles and are elliptic to narrowly ovate in shape and measure from 1-2 cm long and 0.5-1.5 cm with entire to minutely toothed margins.
The flowers are found single in the leaf axils. The glabrous calyx is about 3 mm long while the corolla is a wide, white to pinkish bell approximately 3-4 mm long. The fruit is a bright red berry from 5-6 mm wide (See photo above.).
Matted wintergreen may be found on open, moist ground at and above timberline in the mountains.
Matted wintergreen may be found from British Columbia south through the Cascade Mts. of Oregon and Washington to northern California and east to the Rocky Mts. from Alberta to Colorado.
In the Columbia River Gorge, it may be found between the elevations of 2800'-4000' from near Three Corner Rock east to the high country west of the Wind River and the high country around Eagle Creek.
