Hydrocotyle ranunculoides, often known as 'floating pennywort', has a significant geographical presence, indigenous to parts of Central and South America. 'floating pennywort' has traversed mainland waters, establishing roots across broad regions that include the Mediterranean, parts of central and eastern Africa, as well as a scattering in Eurasia. In areas beyond its native confines, 'floating pennywort' is sometimes thought to be problematic, potentially influencing local flora where its growth is plentiful. Notably, in parts of Europe and Africa, 'floating pennywort' may have an impact on ecosystems due to its robust spread in those environments.
