Hieracium greenei is a small hawkweed forming a basal rosette of densely hairy gray-green leaves, each 5 to 10 centimeters (2-4 inches) long and some with toothed edges. It bolts a thin, hairy stem which reaches 20 to 40 centimeters (8-16 inches) 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.[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=250066959 Flora of North America, Hieracium greenei A.
