Description

Water pennyworts, Hydrocotyles, are very common. They have long creeping stems that often form dense mats, often in and near ponds, lakes, rivers, and marshes, and some species in coastal areas by the sea.{{cite web |url = http://www.aluka.org/action/showCompilationPage?doi=10.5555/AL.AP.COMPILATION.PLANT-NAME-SPECIES.HYDROCOTYLE.BONARIENSIS |archive-url = https://archive.today/20130801230334/http://www.aluka.org/action/showCompilationPage?doi=10.5555/AL.AP.COMPILATION.PLANT-NAME-SPECIES.HYDROCOTYLE.BONARIENSIS |url-status = dead |archive-date = August 1, 2013 |title = Hydrocotyle bonariensis Lam.
