Common Name: buttercup, hairy
Species: Ranunculus sardous Crantz
Bayer Code: RANSA

Two of the common buttercups found in North Carolina are hairy buttercup and bulbous buttercup. Hairy buttercup appears to be predominant in the Piedmont and mountain regions, while bulbous buttercup is readily found in the Piedmont and Coastal Plain regions. Hairy buttercup is a hairy plant with erect, hairy stems (single or branching from the base) and a fibrous root system. Vegetative characteristics of hairy buttercup are similar to those of bulbous buttercup, except for the bulb-like swelling at the base of the stem on bulbous buttercup. Smallflower buttercup is also found in North Carolina, and can be distinguished from hairy buttercup by the lack of hairs on its leaves. In addition, hairy and bulbous buttercup have lobed leaves, whereas most of the lower leaves of smallflower buttercup are unlobed.
