Nymphaeaceae is a family of
flowering plants.
Members of this family are commonly called
water lilies and live as
rhizomatous aquatic herbs in temperate and
tropical climates around the world. The family contains eight large-
flowered genera with about 70 species.
[2] The genus
Nymphaea contains about 35 species in the
Northern Hemisphere.
[2] The genus
Victoria contains two species of giant water lilies
endemic to
South America.
[2] Water lilies are rooted in
soil in bodies of water, with
leaves and
flowers floating on the surface. The leaves are round, with a radial notch in
Nymphaea and
Nuphar, but fully circular in
Victoria.
Water lilies are a well studied
clade of plants because their large flowers with multiple unspecialized parts were initially considered to represent the floral pattern of the earliest flowering plants, and later genetic studies confirmed their evolutionary position as
basal angiosperms. Analyses of floral morphology and molecular characteristics and comparisons with a
sister taxon, the family
Cabombaceae, indicate, however, that the flowers of extant water lilies with the most floral parts are more derived than the genera with fewer floral parts. Genera with more floral parts,
Nuphar,
Nymphaea,
Victoria, have a
beetle pollination syndrome, while genera with fewer parts are pollinated by
flies or
bees, or are self- or
wind-pollinated.
[3] Thus, the large number of relatively unspecialized floral organs in the Nymphaeaceae is not an ancestral condition for the clade.
Horticulturally water lilies have been
hybridized for temperate gardens since the nineteenth century, and the hybrids are divided into three groups: hardy, night-blooming tropical, and day-blooming tropical water lilies. Hardy water lilies are hybrids of
Nymphaea species from the subgenus
Castalia; night-blooming tropical water lilies are developed from the subgenus
Lotos; and the day-blooming tropical plants arise from hybridization of plants of the subgenus
Brachycerasത്
