Nymphaeaceae
Nymphaeaceae
/ˌnɪmfiːˈeɪsiː/ 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.[2] Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. The leaves are round, with a radial notch in Nymphaea
Nymphaea
and Nuphar, but fully circular in Victoria and Euryale. 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
Nymphaeaceae
is not an ancestral condition for the clade. Water lilies do not have surface leaves in the winter time, and therefore the gases in the rhizome lacunae access equilibrium with the gases of the sediment water. The leftover of internal pressure is embodied by the constant streams of bubbles that outbreak when rising leaves are ruptured in the spring.

The Nymphaeaceae
Nymphaeaceae
are aquatic, rhizomatous herbs. The family is further characterized by scattered vascular bundles in the stems, and frequent presence of latex, usually with distinct, stellate-branched sclereids projecting into the air canals. Hairs are simple, usually producing mucilage (slime). Leaves are alternate and spiral, opposite or occasionally whorled, simple, peltate or nearly so, entire to toothed or dissected, short to long petiolate), with blade submerged, floating or emergent, with palmate to pinnate venation. Stipules
Stipules
are either present or absent. Flowers are solitary, bisexual, radial, with a long pedicel and usually floating or raised above the surface of the water, with girdling vascular bundles in receptacle. Sepals
Sepals
are 4-12, distinct to connate, imbricate, and often petal-like. Petals
Petals
lacking or 8 to numerous, inconspicuous to showy, often intergrading with stamens. Stamens
Stamens
are 3 to numerous, the innermost sometimes represented by staminodes. Filaments are distinct, free or adnate to petaloid staminodes, slender and well differentiated from anthers to laminar and poorly differentiated from anthers; pollen grains usually monosulcate or lacking apertures. Carpels

are 3 to numerous, distinct or connate. Fruit is an aggregate of nuts, a berry, or an irregularly dehiscent fleshy capsule. Seeds are often arillate, more or less lacking sperm. Taxonomy[edit] Nymphaeaceae
Nymphaeaceae
has been investigated systematically for decades because botanists considered their floral morphology to represent one of the earliest groups of angiosperms.[3] Modern genetic analyses by the Angiosperm Phylogeny Group researchers has confirmed its basal position among flowering plants.[1][4][5][6] In addition, the Nymphaeaceae
Nymphaeaceae
are more genetically diverse and geographically dispersed than other basal angiosperms.[7][8] Nymphaeaceae
Nymphaeaceae
is placed in the order Nymphaeales, which is the second diverging group of angiosperms after Amborella
Amborella
in the most widely accepted flowering plant classification system, APG IV system.[4][5][6] Nymphaeaceae
Nymphaeaceae
is a small family of three to six genera: Barclaya, Euryale, Nuphar, Nymphaea, Ondinea, and Victoria. The genus Barclaya is sometimes given rank as its own family, Barclayaceae, on the basis of an extended perianth tube (combined sepals and petals) arising from the top of the ovary and by stamens that are joined in the base. However, molecular phylogenetic work includes it in Nymphaeaceae.[9] The genus Ondinea has recently been shown to be a morphologically aberrant species of Nymphaea, and is now included in this genus.[10] The genera Euryale, of far east Asia, and Victoria, from South America, are closely related despite their geographic distance, but their relationship toward Nymphaea
Nymphaea
need further studies.[11][12][13] The sacred lotus was once thought to be a water lily, but is now recognized to be a highly modified eudicot in its own family Nelumbonaceae
Nelumbonaceae
of the order Proteales. As invasive species[edit] The beautiful nature of water lilies has led to their widespread use as ornamental plants. The Mexican water lily, native to the Gulf Coast of North America, is planted throughout the continent. It has escaped from cultivation and become invasive in some areas, such as California's San Joaquin Valley. It can infest slow-moving bodies of water and is difficult to eradicate. Populations can be controlled by cutting top growth. Herbicides can also be used to control populations using glyphosate and fluridone.[14] Symbolism[edit] The white water lily is the national flower of Bangladesh
Bangladesh
and state flower for Andhra Pradesh, India. The seal of Bangladesh
Bangladesh
contains a lily floating on water. The blue waterlily is the national flower of Sri Lanka. It is also the birth flower for July. Lily pads, also known as Seeblätter, are a charge in Northern European heraldry, often coloured red (gules), and appear on the flag of Friesland and the coat of arms of Denmark (in the latter case often replaced by red hearts). The water lily has a special place in Sangam literature
Sangam literature
and Tamil poetics, where it is considered symbolic of the grief of separation; it is considered to evoke imagery of the sunset, the seashore, and the shark. In visual arts[edit] Water lilies were depicted by the French artist Claude Monet (1840–1926) in a series of paintings.
