This, one of the smallest of the Pyrolas, is also one of the commonest. Its flower stalk grows from five to ten inches high, and bears from seven to fifteen very fragrant, greenish white, nodding flowers. The thin, tough, evergreen leaf is broadly oval or elliptical in shape, and narrowed or rounded at the base where it tapers into a short, reddish margined stem. The edges are obscurely dented with low teeth, and the ribs and veins show whitish against the dark green surface. The stems of the tufted leaves are sheathed at the base. The five thin petals of the waxy flower form a little, spreading cup within which are the ten yellow-tipped stamens. The long, curving pistil extends conspicuously beyond the corolla. The five-parted, green calyx spreads to support the petals. The slender flower stalk bears one small leaflet near the middle. The common name was applied because the leaves were formerly used to allay inflammation in bruises and sores. The Shin-leaf is found from June to August, in rich and mostly dry woods, from Canada to the District of Columbia, Illinois, Michigan, Iowa, and along the Rocky Mountains to New Mexico.
