Description

This duckweed is one of Britain's most common small water plants, which forms familiar green mats covering stagnant water bodies (4). It has a simple plant body, known as a thallus, which floats on the surface of the water and measures up to five millimetres in diameter (2). A single root hangs down into the water (2).
