"Ranunculus repens," Wikipedia, the free encyclopedia. The creeping buttercup, is a flowering plant in the buttercup family Ranunculaceae, native to Europe, Asia and northwestern Africa. It is also called creeping crowfoot and (along with restharrow) sitfast. It is a herbaceous, stoloniferous perennial plant growing to 50 cm tall. It has both prostrate running stems, which produce roots and new plants at the nodes, and more or less erect flowering stems. The basal leaves are compound, borne on a 4–20 cm long petiole and divided into three broad leaflets 1.5–8 cm long, shallowly to deeply lobed, each of which is stalked, distinguishing the species from Ranunculus acris in which the terminal leaflet is sessile. The leaves higher on the stems are smaller, with narrower leaflets and may be simple and lanceolate. Both the stems and the leaves are finely hairy. The flowers are golden yellow, glossy, and 2–3 cm diameter, usually with five petals, and the flower stem is finely grooved. The gloss is caused by the smooth upper surface of the petal that acts like a mirror; the gloss aids in attracting pollinating insects and thermoregulation of the flower's reproductive organs. The fruit is a cluster of achenes 2.5–4 mm long. Creeping buttercup has three-lobed dark green, white-spotted leaves that grow out of the node. It grows in fields and pastures and prefers wet soil.
