Ranunculus fascicularis is very similar to R . hispidus var. hispidus , and herbarium specimens without underground parts may be difficult to identify. Ranunculus fascicularis grows in drier habitats; segments of its leaves are commonly oblanceolate and blunt, with few or no marginal teeth; and its petals are widest at or below the middle. Ranunculus hispidus var. hispidus is usually larger in all its parts (leaves, flowers, heads of achenes); leaf segments are variable in shape but their apices are normally sharper and their marginal teeth more numerous, and petals are widest above the middle.
