Nymphaeaceae

(Family)

Overview

[ Back to top ]

Herbs perennial or rarely annual, aquatic. Stems rhizomatous; rhizomes erect or repent, branched or unbranched. Leaves arising from rhizome, simple, alternate, floating, emersed, or submersed, long petiolate but short petiolate on submersed vernal ones; leaf blade undivided, usually with a basal sinus, often peltate. Flowers solitary, axillary, long pedunculate, bisexual, hypogynous to epigynous, actinomorphic, entomophilous, mostly emergent. Sepals 4--7, usually green, occasionally petaloid. Petals numerous (rarely absent), distinct, usually showy, often transitional to stamens. Stamens numerous; anthers introrse, dehiscent by longitudinal slits; connective sometimes appendaged. Pistil 1, compound; carpels 5--many, partially or completely united, surrounding a sometimes projecting floral axis. Ovary multilocular; placentation laminar; ovules numerous. Styles absent or modified into abaxially projecting carpellary appendages. Stigmas radiate on distal surface, often disclike. Fruit berrylike, many seeded, irregularly dehiscent. Seeds mostly arillate; endosperm little, perisperm abundant; embryo small; cotyledons 2, fleshy.

Six genera and ca. 70 species: widespread in temperate and tropical regions; three genera and eight species in China.[1]

The Family Nymphaeaceae is further organized into finer groupings including:

Genera

[ Back to top ]

Barclaya

Barclaya is a genus of 3 - 4 species of flowering plants usually included in the family Nymphaeaceae but sometimes given their own family status as 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 basally. Barclaya are aquatic plants native to tropical Asia. The genus was named in honour of the English gardener and plant collector G. W. Barclay. [more]

Castalia

Cyamus

Euryale

Herbs annual or short-lived perennial. Rhizomes erect, unbranched. Leaves submerged or floating; leaf blade broadly elliptic to orbicular, venation primarily radiate, juvenile ones with basal sinus, mature ones lacking sinus and only slightly indented basally, margin entire, centrally peltate. Flower epigynous, floating or often partially or entirely submerged, cleistogamous or perianth spreading. Sepals 4, greenish, not petaloid, persistent. Petals numerous, in ca. 5 series, showy, transition to stamens gradual. Stamens shorter than sepals and petals, inserted at apex of ovary; filament linear; anther connective unappendaged. Carpels 7--16, completely united. Style absent. Stigma sessile and radiate on cup-shaped stigmatic disc, lacking marginal appendages. Fruit irregularly dehiscent. Seeds smooth, arillate.[2] [more]
