Nymphaea mexicana is a species of aquatic plant that is native to the Southern United States and Mexico as far south as Michoacán. Common names include yellow water lily, Mexican water lily and banana water lily.

Vegetative characteristics

Nymphaea mexicana is a rhizomatous, aquatic, perennial herb with stoloniferous, up to 30 cm long, and 4 cm wide rhizomes. The rhizomes bear leaf and root scars. The stolons are 15–100 cm long, and 0.5–1 cm wide. The ovate, suborbicular, or elliptic lamina is 7–18(–27) cm long, and 7–14(–18) cm wide. The long, cylindrical petiole is glabrous.

Generative characteristics

The floating or emersed, yellow, 6–13 cm wide flowers have peduncles with 4 primary air canals. The flowers have four sepals and 12-30 yellow petals. The androeceum consists of 50 stamens. The gynoecium consists of 7-10 carpels. The spheroid or ovoid fruit bears 3–5 mm long, and 3–5 mm wide seeds with hairlike papillae. Tuberiferous flowers or proliferating pseudanthia can be present.

Taxonomy

Publication

It was published by Joseph Gerhard Zuccarini in 1832. Within the subgenus Nymphaea subg. Nymphaea it is placed in the section Nymphaea sect. Xanthantha.

Hybridisation

Together with Nymphaea odorata, it forms the natural hybrid Nymphaea × thiona.

Etymology

The specific epithet mexicana refers to Mexico.

Cytology

The chromosome count is n = 28. The genome size is 586.80 Mb. The chloroplast genome is 159962 bp long.

Reproduction

Vegetative reproduction

Nymphaea mexicana reproduces vegetatively through stolons. Their structure, resembling bananas, consists of leaf buds and thick, starchy roots. Additionally, tuberiferous flowers or proliferating pseudanthia can be present.

Conservation

The NatureServe conservation status is Vulnerable (G3).

Ecology

Habitat

It occurs in up to 4 m deep water in lagoons, canals swamps, and rivers. It can occur in brackish water.

Herbivory

The canvasback duck, Aythya valisineria, feeds on the banana-like roots of the plant.

As an invasive species

Together with its hybrids, it has become an invasive species outside of its natural range. For instance, it has been recorded in Australia, South Africa, and New Zealand.
