    identification

    The Hieracium is divided into 3 subgenera. Subgenus Chionoracium represents the ±20 native species in North America. Subgenus Hieracium occurs in both North America and Europe. Two native species occur in the PNW; six species from central and eastern Europe also occur in the region. Subgenus Pilosella, entirely European in origin, represents most of the invasive species in the PNW.
