Nuphar sect. Astylus is a section within the genus Nuphar [2] [1] [3] native to North America. [4]
Its species are herbaceous plants. [2]
The flowers have 6–9 sepals. [5] The androecium consists of laminar stamens [6] with long anthers and short filaments. [5] [6] The furrowed, [5] [7] barrel-shaped, [4] ovoid fruit [6] does not have a prominent neck. [6] [7] [4]
It was described by Donald Jay Padgett in 1999 with Nuphar advena(Aiton) W.T.Aiton as the type species. [8] [4]
The section name Astylus means without a style. [10] [11] The fruits of Nuphar sect. Astylus have broad necks, whereas fruits of Nuphar sect. Nuphar have narrow necks [5] or "styles". [4]
It is native to North America. [4]
The fossil species †Nuphar carlquistii from the early eocene of north-central Washington, USA has been identified as member of Nuphar sect. Astylus. [6]
The flowers are pollinated by flies, bees, and beetles. [5]
Nymphaeaceae is a family of flowering plants, commonly called water lilies. They live as rhizomatous aquatic herbs in temperate and tropical climates around the world. The family contains five genera with about 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or rising from the surface. Leaves are oval and heart-shaped in Barclaya. Leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria and Euryale.
Nuphar is a genus of aquatic plants in the family Nymphaeaceae, with a temperate to subarctic Northern Hemisphere distribution. Common names include water-lily, pond-lily, alligator-bonnet or bonnet lily, and spatterdock.
Nuphar lutea, the yellow water-lily, brandy-bottle, or spadderdock, is an aquatic plant of the family Nymphaeaceae, native to northern temperate and some subtropical regions of Europe, northwest Africa, and western Asia. This species was used as a food source and in medicinal practices from prehistoric times with potential research and medical applications going forward.
Nuphar advena is a species of Nuphar native throughout the eastern United States and in some parts of Canada, such as Nova Scotia, as well as Mexico and Cuba. It is locally naturalized in Britain.
Nuphar variegata is rhizomatous, perennial, aquatic herb in the water lily family Nymphaeaceae native to much of Canada and the northernmost of the United States.

Nuphar polysepala, also known as the great yellow pond-lily, wokas, or wocus, is a perennial, rhizomatous, aquatic herb in the genus Nuphar native to western North America. It is commonly found in shallow muddy ponds from northern Alaska and Yukon southward to central California and northern New Mexico, and can be recognized easily by its large floating leaves and bright yellow blossoms.
Nuphar japonica, known as East Asian yellow water-lily, is a perennial, aquatic, rhizomatous, herb in the family Nymphaeaceae native to Japan, Korea, and Russia.

Nuphar carlquistii is an extinct species of flowering plant in the family Nymphaeaceae related to the modern spatterdock, Nuphar advena. The species is known from fossil seeds and fruits found in the early Eocene Okanagan Highlands deposits of northern Washington state and British Columbia, Canada.
Nuphar microphylla is a perennial, rhizomatous, aquatic herb found in North America. It is listed as a special concern and believed extirpated in Connecticut.
Nuphar oguraensis is a species of rhizomatous aquatic plant endemic to Japan.
Nymphaea subg. Nymphaea is a subgenus of the genus Nymphaea.
Nuphar × saijoensis is a species of rhizomatous aquatic plant endemic to Japan. It is a natural hybrid of Nuphar japonica and Nuphar pumila, or Nuphar japonica and Nuphar pumila subsp. oguraensis.
