About Ranunculus fascicularis Muhl. ex Bigelow
Ranunculus fascicularis, commonly called early buttercup, is a species of flowering plant in the buttercup family, Ranunculaceae. It is native to eastern North America, occurring in both Canada and the United States. It is generally widespread across eastern North America, though its populations become sporadic in areas east of the Appalachian Mountains and south of New England. Its natural habitat consists of dry areas with sparse vegetation, including rocky or sandy bluffs, prairies, and savannas. Ranunculus fascicularis is a perennial plant that produces yellow flowers in early spring. It can be difficult to tell apart from the similar-looking species Ranunculus hispidus, which shares most of its geographic range. In general, Ranunculus fascicularis blooms earlier than Ranunculus hispidus, and it is more typically found in drier habitats. It can also be distinguished morphologically: it has pinnately dissected leaves that are longer than wide in outline, while Ranunculus hispidus has palmately dissected leaves that are roughly as wide as they are long. Ranunculus fascicularus also has tuberous roots, a feature that helps separate it from Ranunculus hispidus.
