Ranunculus parviflorus
Encyclopedia
Ranunculus parviflorus is a species of buttercup
known by the common name smallflower buttercup. It is native to Europe, but it is known on other areas of the world as an introduced species
and sometimes a roadside weed, for example, in parts of Australia
and the United States. 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 occur singly in leaf axils. Each flower has a few tiny yellow petals no more than 2 millimeters long; some flowers lack petals. The fruit is an achene
borne in a spherical cluster of usually 10 to 20.
