The foliage of Cursed Crowfoot is more toxic than most Ranunculus spp. (buttercups). During earlier times, beggars reportedly smeared the juices of the foliage on their faces and arms to create blisters that would solicit sympathy and money from passers-by. Cursed Crowfoot can be identified by its succulent palmately lobed leaves and prominent clusters of green pistils in the center of its flowers. Cursed Crowfoot resembles the common Ranunculus abortivus (Small-Flowered Buttercup). The latter species has smaller flowers (about ¼" across) with triangular petals and its seedheads are less elongated and cylindrical at maturity. It also prefers drier habitats than Cursed Crowfoot.
