Duckweed

Duckweed

Duckweed Lemna minor is a tiny plant with a flattened thallus and a single dangling root that is commonly found growing on the surface of ponds. The whole plant is only a few millimetres across but it spreads by vegetative budding and can cover the pond with green. It is a source of food for water birds and for fish. The flowers are minute and rarely found and they have no sepals or petals. Because of its small size duckweed is a useful plant for scientific research. [CH] {EN}
