Ranunculus parviflorus



It is an annual herb producing a mostly erect stem up to 40 centimeters in maximum height. It is coated in soft hairs. The leaves have rounded blades which are toothed, deeply cut, or divided into lobes, which in turn are toothed. The leaves are borne on long petioles, the longest near the base of the plant. Flowers are 3 to 6 mm across and occur singly in leaf axils. Each flower has a few tiny yellow petals no more than 2 millimeters long; some flowers lack petals. The sepals are bent backwards.[2] The fruit is an achene borne in a spherical cluster of usually 10 to 20.
