The water lilies ( Nymphaea ) are a genus of plants in the family of the water lily plants (Nymphaeaceae). The genus, which is common worldwide, comprises around 50 species .

Description and ecology

Water lily species are rarely annuals . Most are perennials and herbaceous plants . These aquatic plants form elongated or bulbous rhizomes with which they are anchored in the mud of rivers, ponds, lakes and other bodies of water.

Most types of water lilies have heterophyllia . Two types of alternate and helically arranged leaves are formed: floating leaves and underwater leaves . The simple leaves have long stalks. The leaf blade is often shield-shaped (peltat), heart-shaped or arrow-shaped. The leaf margin is smooth or serrated. Stipules are present or absent.

The single, hermaphroditic flowers have a screwy structure and are often fragrant. The spectrum of flower colors ranges from white to yellow and red to blue; Varieties can also bloom orange, green, purple, or lavender. The mostly four (rarely three or five) free sepals are mostly greenish. There are six to 50 free petals available. The 20 to 750 free stamens are all fertile or show morphological transitions to the petals as staminodes . The five to 35 carpels are an upper continuous or partially continuous ovary fused partially or completely. The styles end in wide and concave stigmas corresponding to the number of carpels . The pollination is effected by insects ( Entomophilie ). There are night and day flowering species.

The fleshy, spongy, berry-like fruits are crowned with durable scars. After fertilization, the ripening fruits are usually pulled under water and ripen under water. The mature seeds are up to 5 mm in size. They form swimming bags with which the seeds initially float to the surface of the water, where the wind and currents spread them for two to three days. Then the swimming bag dissolves, the seeds sink down and begin to germinate.

Adaptation to the habitat

As a water plant, the water lily is one of the hydrophytes and has some special adaptations that can be seen, for example, in the leaf cross-section. The aim of these morphological adaptations is to make the leaf buoyant (large, air-filled intercellular spaces) and to increase the transpiration rate (large leaves, epidermis with very thin or without cuticula). Neither the upper nor the lower epidermis have stomata, since the gas exchange takes place exclusively via diffusion. The palisade fabric is very dense and multilayered in order to guarantee a high light yield.

The genus Nymphaea was set up in 1753 by Carl von Linné in Species Plantarum , 1, pp. 510-511. Type species is Nymphaea alba L. Synonyms for Nymphaea L. are: Castalia Salisb. , Leuconymphaea Ludw. ex Kuntze .

The worldwide distributed genus Nymphaea includes over 50 species, it is divided into two groups with a total of five subgenera.

use

A large number of varieties have been bred from some species. They are used as ornamental and aquarium plants .

history

Dioscorides , Pliny and Galen distinguished a "white-flowered Nymphaeia" ( Nymphaea alba - white water lily ) from a "yellow-flowered Nymphaeia" ( Nuphar lutea - yellow water lily ). The name "nymphaeia" was derived after Pliny from the fact that a nymph died out of jealousy of Heracles and became a water lily. Because of the club shape of its roots, the plant was also called "rhopalon". Consumption of this root should cause impotence in men for several days . Derived from the damp and cool place of growth, it was especially prescribed against hot diseases such as dysentery .

The similarity of their ripe fruits to the poppy seed capsules led to the name "Papaver palustre" - "Swamp poppy" and to the recommendation of their use against pain .

The yellow color of the root was interpreted as an indication of a relationship to the body juice “cholera” (yellow bile, hot temper…) and so it was called “Kollerwurz” in pharmacies in the 15th and 16th centuries. Accordingly, they were used to treat diseases that arose from an imbalance in the body's fluids (“phlegm” / phlegm - “blood” / sanguis - “yellow bile” / cholera - “black bile” / melancholia ), and when the cholera was in excess or “spoiled”.

Finally, the hair-like shape of the root network suggested its use against hair loss and against skin diseases .

At the turn of the 18th and 19th centuries, the water lilies were reluctantly removed from the lists of the Materia Medica .
