Nuphar

Nuphar is genus of aquatic plants in the family Nymphaeaceae, with a temperate to subarctic Northern Hemisphere distribution. Common names include water-lily (Eurasian species; shared with many other genera in the same family), pond-lily, and spatterdock (North American species).

A total of eight species and three hybrids are currently accepted in the genus.[1] A few botanists treat the genus as just a single variable species (for which the European name N. lutea has priority),[2][3] while 10–12 or more species are accepted by some other authorities.[4] Recent molecular work has shown that there are substantial differences between the Eurasian species (sect. Nuphar) and American species (sect. Astylus), except for North American N. microphylla which is clusters with the Eurasian species.[4][5]

The genus is closely related to Nymphaea. Nuphar differs in having its petals being much smaller than its 4-6 bright yellow-coloured sepals, whereas in Nymphaea, the petals are much larger than the sepals. The fruit maturation also differs, with Nuphar fruit being held above water level to maturity, whereas Nymphaea fruit sink below the water level immediately after the flower closes. Both genera share leaves with a radial notch from the circumference to the petiole (leaf stem) in the centre.

Species[edit]

Hybrids[edit]

  • Nuphar × rubrodisca Morong (N. microphylla × N. variegata)
  • Nuphar × saijoensis (Shimoda) Padgett (N. japonica × N. pumila)
  • Nuphar × spenneriana Gaudin (N. lutea × N. pumila)

Ecology[edit]

Nuphar species occur in ponds, lakes, and slow-moving rivers, growing in water up to 5 metres deep; different species show adaptation to either nutrient-rich waters (e.g. N. lutea) or nutrient-poor waters (e.g. N. pumila).[6]

Alkaloids in the genus include nupharolutine, nuphamine and nupharidine.[7]

Etymology[edit]

The etymology of the word is: medieval Latin nuphar, from medieval Latin nenuphar, thence from Arabic nīnūfar, thence from Persian nīlūfar, thence from Sanskrit nīlōtpala = blue lotus flower.[8] For botanical gender, the name is treated as feminine.[1][4]
