[edit] Growth
It grows in eutrophic freshwater beds, with its roots fixed into the lake bed and its leaves floating on the water surface; it can grow in water up to 5 metres deep.[3] The flower is solitary, terminal, held above the water surface; it is hermaphrodite, 2–4 cm diameter, with five or six large bright yellow sepals and numerous small yellow petals largely concealed by the sepals. Flowering is from June to September, and pollination is entomophilous, by flies attracted to the alcoholic scent.[3] The flower is followed by a green bottle-shaped fruit, containing numerous seeds which are dispersed by water currents. The species is less tolerant of water pollution than water-lilies in the genus Nymphaea.[3]
[edit] Taxonomy
Some botanists have treated Nuphar lutea as the sole species in Nuphar, including all the other species in it as subspecies and giving the species a holarctic range,[4][5] but the genus is now more usually divided into eight species (see Nuphar for details).[6]
