  1. Ranuculaceae“Buttercup Family” By: Levi Eggermont

  2. General info • The Ranunculaceae are herbs or rarely shrubs or vines comprising 25-81 genera and 2,000-2,500 species. The leaves are typically alternate, compound, and estipulate. • The flowers are actinomorphic or less commonly zygomorphic and are usually bisexual. The perianth is usually in two, often 5-merous cycles that may or may not be differentiated into calyx and corolla. The petals are usually nectariferous near the base, and in Ranunculus there is a flap of tissue in this position. • Typical flowers have many helically disposed stamens and simple pistils on an elongated receptacle. All of the floral parts are distinct. Each pistil has a superior ovary with one locule and 1-several parietal ovules. A single flower commonly produces a cluster of achenes or follicles.
