Dodder) is a genus of about 100-170 species of yellow, orange or red (rarely green) parasitic plants. Formerly treated as the only genus in the family Cuscutaceae, recent genetic research by the Angiosperm Phylogeny Group has shown that it is correctly placed in the family Convolvulaceae. The genus is found throughout the temperate to tropical regions of the world, with the greatest species diversity in subtropical and tropical regions; the genus becomes rare in cool temperate climates, with e.g. only four species native to northern Europe.

"Water Dropwort is a genus of plants of the natural order Umbelliferæ. A number of species are natives of Great Briatin, large perennial plants, with a strong and generally disagreeable aromatic smell, and compound or decomposed leaves. The common water dropwort and the hemlock water dropwort, or water hemlock, are both common in wet places in Great Britain and throughout Europe, and both are narcotic acid poisons. The roots of the latter have some resemblance to parsnips, and hence fatal accidents have frequently occurred. The fine-leaved water dropwort, called water fennel by the Germans, is also common in ditches and ponds both in Great Britain and on the Continent. It is not so poisonous as the other species just named. It was at one time erroneously regarded as a specific against pulmonary consumption; but it has been advantageously employed in pulmonary complaints."—(Charles Leonard-Stuart, 1911)

An illustration of duckweed. Duckweed is an important food source for waterfowl and are eaten by humans in some parts of Southeast Asia (as khai-nam). Some duckweeds are used in freshwater aquariums and ponds where they may spread rapidly, although in a large pond they may be difficult to eradicate once established. The plants can provide nitrate removal (if cropped) and cover for fry. The plants are used as shelter by pond water species, such as bullfrogs and bluegills. The duckweeds are important in the process of bioremediation because they grow rapidly, absorbing excess mineral nutrients, particularly nitrogen and phosphates. A cover of duckweeds will reduce evaporation of water compared to a clear surface.
