The leaf blades are round or kidney-shaped and are divided into three parts that may be subdivided. The yellow petals are 4 to 14 millimeters long. Ranunculus gmelinii occurs in wetland habitats and on shorelines.[3]

The plant is not a threatened species,[2] but it becomes rare in the habitat on the edges of its range; it is protected as a threatened plant in the state of Maine, and var. hookeri is a state-listed endangered plant in Wisconsin.[4] It is listed as an endangered species in Newfoundland and Labrador.[5]

This species was named in honor of Johann Georg Gmelin (1709-1755).[6]
