Nymphaeaceae - Wikipedia. Cultivar of Nymphaea in flower. 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 7. The leaves are round, with a radial notch in 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 beetlepollination syndrome, while genera with fewer parts are pollinated by flies or bees, or are self- or wind- pollinated. 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 Brachyceras. 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 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 are 4- 1. 2, distinct to connate, imbricate, and often petal- like. Petals lacks or 8 to numerous, inconspicuous to showy, often intergrading with 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. 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. 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. The blue waterlily is the national flower of Sri Lanka. It is also the birth flower for July. Lily pads, also known as Seebl. Soltis and Michael Zanis, Systematic Botany, Vol. Evolution of garden Nymphaeas, G. Khoshoo, Current Science, 5.
