Rhus boothillensis is an extinct species of flowering plant in the sumac family Anacardiaceae. The species is known from fossil leaves found in the early Eocene deposits of northern Washington State, United States. The species was first described from fossil leaves found in the Klondike Mountain Formation. Rhus boothillensis likely hybridized with the other Klondike Mountain formation sumac species Rhus garwellii, Rhus malloryi, and Rhus republicensis.
Rhus republicensis is an extinct species of flowering plant in the sumac family, Anacardiaceae. The species is known from fossil leaves found in the early Eocene deposits of northern Washington state in the United States.
