Nymphaea atrans is a species of waterlily is endemic to Queensland, Australia. [2]
Nymphaea atrans is a perennial plant with vertical, short, and swollen rhizomes. The leaf blades with toothed margins of 2mm long, regularly spaced teeth may reach 40 cm in width. The base of the petiole is winged. [3]
The flowers may rise up to 40 cm above the water level. [3] Over time, the colour of Nymphaea atrans flowers shifts from blue and white to a deep pink. [4] [5] Each flower has ca. 300 stamens with 14 mm long, cylindrical to membranous filaments. The anthers, typically featuring a small hooked apical appendage, can reach up to 10 mm in length. [3]
The nuclear genome size is 1408.32 Mb, and the chromosome count is n = 42. [6] The chloroplast genome is 160,990 bp long. [7]
Flowering occurs from July to November. [3]
Natural hybrids of Nymphaea atrans with Nymphaea immutabilis with reduced fertility have been reported from areas of sympatric occurrence. [8] Apart from the reduced fertility, the hybrids can be identified through the lighter pink colouration of older flowers, as they do not darken to the darker shades found in Nymphaea atrans. [3] It was reported that in one hybrid population most individuals do not exhibit the characteristic shift in floral colouration. Additionally, even those that do exhibit this characteristic shift do not reliably produce offspring with the same trait from seed. [9]
It was first described by Surrey Wilfrid Laurance Jacobs in 1992. [2]
The type specimen was collected by Surrey Wilfrid Laurance Jacobs and J. Clarkson along the Bathurst Bay road north of Wakooka in Queensland, Australia on the 31st of July 1987. [3]
It is placed in Nymphaea subgenus Anecphya. [8] [7]
It is close to Nymphaea immutabilis . Despite morphological differences, a molecular study was unable to differentiate both species based on the nuclear marker ITS, as well as the chloroplast marker trnT-trnF. [10]
The specific epithet atrans is derived from the Latin "atrans", meaning darkening, which references the shift of floral colouration from blue and white to a deep pink in ageing flowers. [3]
The NCA status of Nymphaea atrans is Special Least Concern. [1]
It occurs in the Cape York Peninsula of northern Queensland, Australia. [11] It occurs in Billabongs, lakes, and former pastoral dams on floodplains. [3]
Because of its outstanding, showy ornamental qualities, this species is grown in waterscape gardens globally and is well-suited for use as display plants in water gardens. [7] [11] [12] It has been used in the creation of several new Nymphaea hybrids. [13]
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 70 known species. Water lilies are rooted in soil in bodies of water, with leaves and flowers floating on or emergent from the surface. Leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria and Euryale.
Nymphaea is a genus of hardy and tender aquatic plants in the family Nymphaeaceae. The genus has a cosmopolitan distribution. Many species are cultivated as ornamental plants, and many cultivars have been bred. Some taxa occur as introduced species where they are not native, and some are weeds. Plants of the genus are known commonly as water lilies, or waterlilies in the United Kingdom. The genus name is from the Greek νυμφαία, nymphaia and the Latin nymphaea, which mean "water lily" and were inspired by the nymphs of Greek and Latin mythology.
Nuphar is a genus of aquatic plants in the family Nymphaeaceae, with a temperate to subarctic Northern Hemisphere distribution. Common names include water-lily, pond-lily, alligator-bonnet or bonnet lily, and spatterdock.
Nymphaea lotus var. thermalis is a variety of Nymphaea lotus native to Romania.
Nymphaea leibergii, also known as the dwarf waterlily and Leiberg's waterlily, is a perennial emergent aquatic plant belonging to the genus Nymphaea. It can be found across northern North America in ponds and slow moving streams. Populations of this plant are infrequent throughout its range, and it is protected as a state threatened plant in Maine, Michigan, and Minnesota.
Nymphaea ondinea is a flowering aquatic plant in the family Nymphaeaceae native to northwestern Australia.
Albert de Lestang was a French-Australian botanist. From his North Queensland property, Adel's Grove, de Lestang supplied seeds and plants to botanical gardens around the world. In 1946 he supplied seeds of a rare white-flowered water lily that the botanical world had been chasing since 1852. The seeds were sent to Kew Gardens but forwarded to Texas for propagation. The lily was originally referred to as a form of Nymphaea gigantea but is currently identified as a new species N. carpentariae. The cultivar 'Albert De L'Estang' is thought to be a different species, N. immutabilis.
Nymphaea tetragona is an aquatic perennial, species of flowering plant commonly called pygmy waterlily and small white water lily, belonging to the family Nymphaeaceae.
