Facelis retusa is an annual herb with the stems up to 30 cm (1-foot) long, very often trailing along the surface of the ground. Leaves are crowded along the stem, each up to long. Flower heads are in clusters, with white or purple disc flowers but no ray flowers. The achene has several long, feathery bristles that give a white appearance and assure effective seed dispersal.Flora of North America, Facelis Cassini, 1819.
