Hieracium schultzii (not to be confused with the European H. schultesii), or roughstem hawkweed[3] is a North American plant species in the dandelion tribe within the sunflower family. It is widespread across much of Mexico with a few populations in Guatemala and western Texas.[4][5][6]
Hieracium schultzii is an herb up to 70 cm (2.3 ft) tall with many hairs. Leaves are both on the stem and at the bottom. Leaves are up to 150 mm (5.9 in) long. One stalk can produce 3-25 flower heads in a conical or flat-topped array. Each head has 25-40 yellow ray flowers but no disc flowers.[7]
