Oenanthe crocata is an endemic plant of Sardinia and Corsica. It belongs to the Apiaceae (Umbelliferae) family and grows in wet zones, marshes, and swamps at altitudes of between 0 and 1000 m. The oil of this plant is little studied, but its extracts are well known for their high toxicity.
Its morphological characteristics are hemicryptophytic with leaves similar to parsley, roots with more or less ovoid tubers, tubulous and fluted stem, and 3/4 pennatifid lower leaves with cuneate segments; the 2/3 cauline leaves are pinnate with thinner segments that evolve into linear. The umbels have 10/40 radii with a thin 4/6 mm fruit with elongated styli (24-26). The plant was picked in the balsamic period (June-July) along the river Bonorchis, in the territory of Abbasanta (Nuoro), more precisely in the area between 4°83’ and 4°84’ W longitude and 44°44’ and 44°45’ N latitude.
