4-3-2021 ULLAL DE BALDOVI, VALENCIA - CURSED CROWFOOT (Ranunculus sceleratus)

Cursed Crowfoot (Ranunculus sceleratus) is a highly toxic wetland plant known for its blistering sap. Native to North America and Eurasia, this "little frog" of the buttercup family earned its wicked reputation from a potent toxin called protoanemonin, which causes severe skin irritation and mucosal blistering upon contact.

Key Facts About Cursed Crowfoot

The Name Origin: The genus name Ranunculus stems from the Latin for "little frog", referencing its preferred habitat in marshes, wet ditches, and streambanks.

Toxicity: All parts of the plant contain protoanemonin. While the toxin degrades as the plant dries out, handling it fresh can result in painful dermatitis, blisters, and inflammation. If ingested, it causes burning of the mouth and severe gastrointestinal distress.

Historical Folklore: Legend states that ancient beggars used the irritating sap to induce artificial sores and rashes on their skin to provoke public pity and boost their earnings.

Appearance: It features stout, smooth, hollow stems reaching up to 2 feet tall. It produces tiny, bright yellow flowers (about \(\frac{1}{3}\) inch across) with five petals and a very distinct, elongated cylindrical seed head in the center.

Ecological Status: Despite its toxicity to livestock and humans, it holds a "Least Concern" conservation status and serves as a naturalized wetland feature throughout much of the Northern Hemisphere.
