WATER-LILY, a name somewhat vaguely given to almost any floating plant with conspicuous flowers, but applying more especially to the species of Nymphaea, Nuphar, and other members of the order Nymphaeaceae.
Many beautiful Nymphaea hybrids have been raised between the tender and hardy varieties of different colours, and there are now in commerce lovely forms having not only white, but also yellow, rose, pink and carmine flowers.
Amongst hardy species of Nymphaea now much grown are candida, nitida, odorata, pygmaea and tuberosa, all with white, more or less sweet-scented flowers; flava, yellow, and sphaerocarpa, rose-carmine.
With these might be associated the gigantic lily of Queensland (Nymphaea gigantea), the leaves of which float on water, and are quite 18 in.
For example, the difference between aquatic ants with floating leaves, such as the yellow water-lily (Nymphaea l~
Aquatic plants with submerged and floating leaves: Glyceria fluitans, Ranunculus peltatus, Nymphaea (Nuphar) - lutea, Callitriche stagnalis, Potamogeton polygonifolius.
The nymphaea of the Roman period were borrowed from the constructions of the Hellenistic east.
Such nymphaea existed at Corinth, Antioch and Constantinople; the remains of some twenty have been found at Rome and of many in Africa.
Thus, the Lent lily is Narcissus Pseudonarcissus; the African lily is Agapanthus umbellatus; the Belladonna lily is Amaryllis Belladonna (q.v.); the Jacobaea lily is Sprekelia formosissima; the Mariposa lily is Calochortus; the lily of the Incas is Alstroemeria pelegrina; St Bernard's lily is Anthericum Liliago; St Bruno's lily is Anthericum (or Paradisia) Liliastrum; the water lily is Nymphaea alba; the Arum lily is Richardia africana; and there are many others.
A structure called the cool orchid house is set apart for the accommodation of the many lovely mountain species from South America and India, such as odontoglossums, masdevallias, &c., and in this the more uniform the temperature can be kept the better, that in summer varying between Cyanophyllum (Miconia) Cycas Dieffenbachia Dipladenia* Dracaena Eranthemum Eucharist Euphorbia Ficus Franciscea Gardenia Gesnera Gloriosa* Gloxinia f Heliconia f Hoffmannia I pomaea * Ixora Jacobinia Jasminum* Luculia Maranta Medinilla Meyenia Musa Nelumbium f Nepenthes Nymphaea f Oxera * Pancratium f Pandanus Passiflora* Pavetta Petraea * Pleroma* Poinsettia Rondeletia Sanchezia Schubertia* Scutellaria Stephanotis Tabernaemontana Terminalia Thunbergia Torenia Thyrsacanthus Tydaea Vinca Abutilon Acacia Agapanthus Agathaea Agave Alonsoa Aloysia Amaryllis Ardisia Asparagus Aspidistra Asystasia (Mackaya) Azalea Bauera Begonia Blandfordia Bomarea * Boronia Bougainvillea * Bouvardia Brugmansia Calceolaria Camellia Campanula Canna Celosia Cestrum * Chorizema* Chrysanthemum Cineraria 60° and 65°, and in winter from 45° to 60°.
In Nymphaea micrantha buds appear at the upper part of the petiole.
Water-lilies of the genera Nymphaea and Nelumbium occur.
In plants, as Nymphaea alba, where a spiral arrangement of the floral leaves occurs, it is not easy to say where the calyx ends and the corolla begins, as these two whorls pass insensibly into each other.
Covering the ovary in Nymphaea (Castalia) and Nelumbium may be regarded as a form of disk.
