Description

Vegetative characteristics

Nuphar pumila is a perennial, [7] [5] rhizomatous, aquatic [2] herb [6] with 20–70 cm long, [7] and 1–3 cm wide rhizomes. [8] The ovate [7] leaves are 5–10(–13) cm long, [9] and 6–12 cm wide. The pubescent petiole is 20–50 cm long. [8] The submerged leaves are round and wrinkled. [6]

Generative characteristics

The yellow, [8] actinomorphic, [6] faintly fragrant, [10] 1–4.5(–6) cm wide flowers have pubescent, 40–50 cm long peduncles [8] The five [11] ovate to spathulate sepals are 16–29 mm long, and 9–16 mm wide. [12] The abaxial surface of the sepals is often green. [9] The flower has 9–13 petals. [12] The androecium consists of 35–65 stamens. The gynoecium consists of 7–12 carpels. [13] The star-shaped stigmatic disk with 7–12 stigmatic rays is 6–8.5 mm wide. [10] The green, [12] 1–2 cm wide fruit [8] bears greenish brown, [12] ovoid to oblong, 3–5 mm long seeds. [8]

Cytology

The chromosome count is 2n = 34. [8] The chloroplast genome is 160737 bp long. [14]

Taxonomy

It was first published as the variety Nymphaea lutea var. pumilaTimm by Joachim Christian Timm in 1795. [2] Later, it was elevated to the status of the separate species Nuphar pumila(Timm) DC. published by Augustin Pyramus de Candolle in 1821. [11] [2] It is placed in the section Nuphar sect. Nuphar. [15]

Etymology

The specific epithet pumila means small. [16] [17]

Distribution

Nuphar pumila is native to China, Japan, Korea, Mongolia, Russia, [8] Switzerland, [9] the United Kingdom, [5] Austria, Germany, France, Spain, [18] Finland, Sweden, Denmark, and Poland. [2]

In Europe, the typical subspecies Nuphar pumila subsp. pumila is present. [18]

Conservation

The IUCN conservation status is least concern (LC). [1] However, it is threatened by hybridisation with Nuphar lutea, [18] [19] [20] [9] climate change, [20] pollution, and habitat destruction. [9] It is classified as endangered in Switzerland, [19] vulnerable in France, [21] and endangered in Poland. [7]

Ecology

Habitat

It occurs in lakes, ponds [8] and slowly flowing rivers [6] in nutrient-poor waters at depths of 0.5–3 m. [9]

Herbivory

The leaf mine species Hydromyza livens feeds on Nuphar pumila leaves. [22]

Common names

Nuphar pumila is also known as least water lily [23] or least yellow water-lily. [6]

Uses

It is cultivated as an ornamental plant. [23]
