"Hieracium scouleri" is a species of hawkweed known by the common name Scouler's woollyweed. It is native to western North America from Manitoba to California, where it grows in a variety of mountainous habitats. This plant produces a basal rosette of long, narrow leaves 10 to 20 centimeters long, which are generally hairy to bristly. It bolts an erect stem 30 to 70 centimeters tall which bears the inflorescence. The flower heads have large, curling bracts with glandular hairs or bristles, long, protruding disc florets and bright yellow ray florets. The achene is about 3 millimeters long.

There are several varieties. One variety, var. "albertinum", is often treated as a separate species, "Hieracium albertinum". [ [http://plants.usda.gov/java/profile?symbol=HISCA USDA Plants Profile: "H. albertinum"] ]
