Discussion
In North America, Ranunculus ficaria seems to be expanding its range rapidly in areas with cool mesic climates.
The species is extremely variable (especially in leaf size and stem posture), and many attempts have been made to divide it into varieties or subspecies (see P. D. Sell 1994). The different forms, however, intergrade extensively and the varieties are often impossible to distinguish.
Selected References
