Family: ARACEAE: Species: Spirodela polyrhiza (L.)Schleiden: Common Name: COMMON DUCKWEED: Plant Notes: The Linnaean protologue of the basionym spelled the epithet as "polyrhiza" which is retained here, although Schleiden then changed the epithet to "polyrrhiza" when making the combination in Spirodela, a spelling used by some authors. Common names Stor andemad in Danish Stor andemad in Danish Stor andemat in Norwegian Teichlinse in German Vielwurzelige Teichlinse in German Duckweed was exposed to six different cadmium concentrations, such as, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 mg/L and the experiment was continued for 22 days. & Hallb.) Macrophytes have been used to mitigate eutrophication and upgrade effluent quality via their nutrient removal capability. This document is now under preparation for its final publication. Spirodela polyrhiza has been used as a traditional remedy for the treatment of urticarial, acute nephritis, inflammation, as well as skin disease. It has been investigated for use as a biofuel, for bioremediation of over nitrified waters, and as a food for domestic livestock and humans.--A. It is a suitable system because variation among its clonally produced offspring cannot be a product of genetic variation, and because it inhabits variable environments in which the timing of turion formation is expected to have direct fitness consequences. masonii Daubs Telmatophace orbicularis (Kit. We find that this geographically widespread and numerically abundant species has very low levels of genetic diversity. Govaerts, R. et al. 3. 2019.
