Ranuculaceae
“Buttercup Family”
By: Levi Eggermont
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.
