Ranunculus bulbosus
Ranunculus uncinatus
Ranunculus bulbosus is native to Europe and the Near East but has become naturalized in many other parts of the world. It is considered an introduced weed in the flora.
The Iroquois used Ranunculus bulbosus as a toothache remede and as a a treatment for venereal disease (D. E. Moerman 1986).

Plants with hispid stems and achenes are often separated as Ranunculus uncinatus var. parviflorus; these two characters are poorly correlated, however, and sometimes vary between plants in a single collection. Ranunculus uncinatus was reported from northeastern Alberta and adjacent Northwest Territories by H. J. Scoggan (1978-1979, part 3). The specimens have hairy receptacles and straight, broad achene beaks; they apparently represent small individuals of R. macounii.
Some Native Americans used Ranunculus uncinatus as an antrirheumatic, a diaphoretic, a disinfectant, and an orthopedic aid, as well as in herbal steam baths intended to soothe sore muscles and rheumatism (D. E. Moerman 1986).
