Scientific profile
Lemna trisulca is a small, herbaceous aquatic plant, typically 1–1.2 cm tall, with broad, leaf-like fronds that measure around 13 mm² in area. It is not woody and grows entirely submerged or just beneath the water surface, often forming loose, interconnected colonies. The species favours sunny, still or slow-moving waters that are nutrient-rich and neutral to slightly acidic. It is most characteristic of wet meadows, swampy ground and tall-herb fringes. Flowering takes place in May and June. The minute diaspores weigh approximately 0.05 mg.
