Erythronium revolutum is a species of flowering plant in the lily family which is known by several common names, including mahogany fawn lily, coast fawn lily, and pink fawn lily. This plant is native to the west coast of North America from northern California to British Columbia. It is most abundant within 100 miles of the coast, and it is found in moist places, such as streambanks, bogs, and wet forest understory. This wildflower grows from an oval-shaped bulb 3 to 5 centimeters long and produces usually two wide, flat, mottled green leaves near the ground. It sends up a long, naked stalk which bears one or two showy lily flowers. The stalk bows at the end so that the face of the flower points at the ground. There are six petals in shades of pink or light purple which may have yellow or white spotting toward the center of the flower. The petals may be straight or recurved so far that their tips meet behind the flower. The anthers are bright yellow. The fruit is a capsule up to 6 centimeters long.
