Hieracium longiberbe is an herb up to 50 cm (20 in) tall, with leaves mostly on the stem rather than in a rosette at the bottom. Leaves, stems, and the bracts surrounding the flower heads are covered with long and conspicuous hairs up to 8 mm (0.31 in) long. Leaves are up to 100 mm (3.9 in) long, with no teeth on the edges. One stalk will produce 3-12 flower heads in a flat-topped array. Each head has 12-24 yellow ray flowers but no disc flowers.[4]
