Hieracium traillii is a species of hawkweed known by the common name Maryland hawkweed.[5]
Hieracium traillii grows in the eastern United States, primarily in the central Appalachian Mountains of Pennsylvania, Maryland, Virginia, and West Virginia, with some populations farther west in Ohio and Kentucky. [6]
Hieracium traillii is a small hawkweed forming a basal rosette of densely hairy gray-green leaves, each up to 8 centimeters (3.2 inches) long and some with toothed edges. It bolts a thin, hairy stem which reaches 60 centimeters (2 feet) tall. The stem bears an inflorescence of several flower heads containing yellow ray flowers but no disc flowers. The fruit is a ribbed achene about half a centimeter (0.2 inches) long with a light brown pappus.[7]
