Habitat and Ecology

Habitat and Ecology
N. lutea typically occurs in slow-flowing or standing, mesotrophic or eutrophic water bodies such as ponds, lakes, rivers and canals. It will also occur in oligotrophic conditions. In Iran this species occurs in so called "Sarab" which is a local word for ponds that form at the mouth of springs.

Conservation Actions

There are no conservation measures in place or needed. As a rather rare plant in East Mediterranean it requires measures to reduced current abstraction of water resources in particular in the western Iran.

Nuphar lutea

Nuphar lutea (Yellow Water-lily, Brandy-Bottle) is an aquatic plant of the family Nymphaeaceae, native to temperate regions of Europe, northwest Africa, and western Asia.[1][2]

Ecology[edit]

This aquatic plant grows in shallow water and wetlands, with its roots in the sediment and its leaves floating on the water surface; it can grow in water up to 5 metres deep.[3] It is usually found in shallower water than the white water lily, and often in beaver ponds. Since the flooded soils are deficient in oxygen, aerenchyma in the leaves and rhizome transport oxygen to the rhizome. Often there is mass flow from the young leaves into the rhizome, and out through the older leaves.[4] The rhizomes are often consumed by muskrats. 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]

Taxonomy[edit]

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,[5][6] but the genus is now more usually divided into eight species (see Nuphar for details).[7]

Symbolism[edit]

Flag of Frisia

Stylized red leaves of the yellow water lily, known as seeblatts or pompeblêden are used as a symbol of Frisia. The flag of the Dutch province of Friesland features seven pompeblêden.

Names and Taxonomy

Taxonomy

Comments: The taxonomic classification of the yellow pond-lilies (Nuphar) is currently unsettled; see the discussion by Wiersema and Hellquist (Flora of North America, vol. 3, 1997). Nuphar lutea was named from Europe, and is considered by some, including Beal (1956, J. Elisha Mitchell Sci. Soc. 72: 317-346) and Kartesz (checklist, 1994, and review draft checklist 8/98) to include as subspecies several North American taxa. On the other hand, the North American plants are often treated as several species instead (as by Wiersema and Hellquist in FNA). Appropriate nomenclatural combinations have not been made to allow treatment of the North American plants as subspecies of a North American species (excluding the European species Nuphar lutea). The Kartesz treatment is followed here, with synonymy provided for the names in FNA. Also, the gender of the generic name Nuphar has been debated; although often treated as neuter, it is considered feminine, with endings of scientific names corrected as needed. As treated here, Nuphar lutea ssp. lutea is a plant of Europe, Asia eastward to Manchuria and central Siberia, and southward to Algeria, Palestine, and Iran.
