| Identification | Hairy Buttercup has sometimes been misidentified as R. bulbosus, which it closely resembles in life. If fruiting, Hairy Buttercup can readily be told by its papillose (tiny bumps) seeds (vs. smooth or ridged in that species). In flower, the petals of Hairy Buttercup are 7-10 mm long (vs. 9-13 mm long in R. bulbosus). | |
