Vegetative characteristics

Nymphaea mexicana is a rhizomatous,[5] aquatic,[6] perennial herb[7] with stoloniferous,[8][5] up to 30 cm long, and 4 cm wide rhizomes.[8] The rhizomes bear leaf and root scars.[9] The stolons are 15–100 cm long, and 0.5–1 cm wide.[10] The ovate, suborbicular,[9] or elliptic lamina is 7–18(–27) cm long, and 7–14(–18) cm wide.[5] The long, cylindrical petiole[9] is glabrous.[5]

Generative characteristics

The floating or emersed,[5] yellow, 6–13 cm wide flowers have peduncles with four primary air canals.[10] The flowers have four sepals[6] and 12–30 yellow petals.[5] The androecium consists of 50 stamens.[8] The gynoecium consists of seven to ten carpels.[5] The spheroid or ovoid fruit bears 3–5 mm long, and 3–5 mm wide seeds[11] with hairlike papillae.[11][5] Tuberiferous flowers or proliferating pseudanthia can be present.[12]

Cytology

The chromosome count is n = 28. The genome size is 586.80 Mb.[13] The chloroplast genome is 159962 bp long.[14]

Taxonomy

It was published by Joseph Gerhard Zuccarini in 1832.[9][2] Within the subgenus Nymphaea subg. Nymphaea[15] it is placed in the section Nymphaea sect. Xanthantha.[16][10]

Etymology

The specific epithet mexicana refers to Mexico.[6]

Hybridisation

Together with Nymphaea odorata, it forms the natural hybrid Nymphaea × thiona.[5]

Reproduction

Vegetative reproduction

Nymphaea mexicana reproduces vegetatively through stolons. Their structure, resembling bananas, consists of leaf buds and thick, starchy roots.[17] Additionally, tuberiferous flowers or proliferating pseudanthia can be present.[12]

Conservation

The NatureServe conservation status is Vulnerable (G3).[1]

Ecology

Habitat

It occurs in up to 4 m deep water[18] in lagoons, canals[19] swamps, and rivers.[20] It can occur in brackish water.[19]

Herbivory

The canvasback duck, Aythya valisineria, feeds on the banana-like roots of the plant.[21]

As an invasive species

Together with its hybrids, it has become an invasive species outside of its natural range.[22][23] For instance, it has been recorded in Australia,[8][20] South Africa,[22] New Zealand,[11][6] and the Iberian Peninsula.[24]
