Pilosella floribunda (synonym Hieracium floribundum, ^[1] also known as pale hawkweed, smoothish hawkweed, ^[2] yellow hawkweed, ^[3] and yellow devil hawkweed ^[4] ) is a species of noxious and herbaceous perennial plant from family Asteraceae that is known in Europe (particularly France) ^[4] and can also be found in United States and Canada. ^[5] It was believed that it was a hybrid of Pilosella caespitosa (Hieracium caespitosum and Pilosella lactucella (Hieracium lactucella). ^[2]
