Ranunculus flammula
Ranunculus flammula, the lesser spearwort, greater creeping spearwort or banewort, is a species of perennial herbaceous plants in the genus "Ranunculus" (buttercup), growing in damp places throughout the Boreal Kingdom. It flowers June/July. "Ranunculus flammula" is poisonous. It is very closely related to "R. reptans", which is distinguished by prostrate and more slender stems, narrower leaves and smaller flowers and is sometimes included within "R. flammula" sensu lato as a variety ("R. flammula" var. "reptans" (L.) E. Meyer). In addition to other forms of pollination, this plant is adapted to rain-pollination.
