Description

Vegetative characteristics

Nymphaea immutabilis is an annual or perennial plant with globose rhizomes. [3] The round, 70 cm wide leaves have dentate margins. [4] [3]

Generative characteristics

The flowers extend up to 50 cm above the water surface. [4] The flowers have four sepals, and 34 petals. The androecium consists of 400 stamens. The gynoecium consists of 9-20 carpels. [3] The globose, 5 cm wide fruit bears numerous 4 mm long, and 2.5 mm wide, rounded seeds with trichomes arranged in irregular rows. [4] Immature seeds are red, but mature to brownish-grey seeds. [5] The seeds have a mechanism of physiological dormancy. [6]

Cytology

The chromosome count is n = 42. The genome size is 1408.32 Mb. [7]

Reproduction

Generative reproduction

Flowering occurs from March to November. [4] [3]

Taxonomy

Publication

It was first described by Surrey Wilfrid Laurance Jacobs in 1992. [2]

Type specimen

The type specimen was collected by S. Jacobs and J. Clarkson near Mareeba, Queensland, Australia on the 26th of July 1987. [3]

Placement within Nymphaea

It is placed in Nymphaea subgenus Anecphya. [6]

Separation of Nymphaea kimberleyensis

The subspecies Nymphaea immutabilis subsp. kimberleyensis S.W.L.Jacobs was described in 1992. Later in 2011, it was elevated to a separate species Nymphaea kimberleyensis (S.W.L.Jacobs) S.W.L.Jacobs & Hellq. [8] [9]

Etymology

The specific epithet immutabilis, meaning unchanging, references the floral colouration, which does not change as the flower ages. [3]

Conservation

The NCA status of Nymphaea immutabilis is Special Least Concern (SL). [1] In the Northern Territory it is categorised as vulnerable. [10] [11]

Ecology

Habitat

It occurs in swamps, [6] permanent, or temporary waters, [3] billabongs, streams, and rivers. [5]

<span class="mw-page-title-main">Nymphaeaceae</span> Family of plants

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.

<i>Nymphaea</i> Genus of aquatic plants

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.

<i>Nymphaea nouchali <span style="font-style:normal;">var.</span> caerulea</i> Species of plant

Nymphaea nouchali var. caerulea, is a water lily in the genus Nymphaea, a botanical variety of Nymphaea nouchali.

<i>Nymphaea thermarum</i> Species of water lily

Nymphaea thermarum is a species of water lily that is endemic to Rwanda. Once thought to be extinct in the wild, all wild plants were lost due to destruction of its native habitat, but it was saved from extinction when it was grown from seed at the Royal Botanic Gardens, Kew in 2009. A previously-unknown wild population was discovered in 2023.

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.
