Cursed crowfoot is rare in Connecticut; the state classifies it as a species of special concern. It is one of six species of small-flowered buttercups found in Connecticut. Identifying features for cursed crowfoot include a hairless, wide, hollow stem; tall, cylindrical seed heads; deeply lobed basal leaves; and its preference for very wet soil. Juice from the stems is said to cause blisters; this may be why the plant is called "cursed."
