DescriptionWolffiaArrhiza2.jpg
English: The smallest species of vascular plants in Europe – Spotless watermeal, Wolffia arrhiza – on human fingers. Every single speck of less than 1 mm length is an individual plant. (Worldwide, only a few other species of the genus Wolffia might be, "somewhat smaller.")
Deutsch: Die kleinste Blütenpflanze Europas – die Wurzellose Zwergwasserlinse, Wolffia arrhiza – zum Größenvergleich auf Fingern. Jedes der "Kügelchen" ist eine eigene Pflanze. (Noch kleiner sind weltweit wohl nur manche anderen Vertreter der Gattung Wolffia.)
