Description
=Vegetative characteristics=
Nymphaea lingulata is an aquatic herbPellegrini, M. O. O. & Jardim Botânico do Rio de Janeiro. (n.d.-b). Nymphaea lingulata Wiersema Flora E Funga Do Brasil. Retrieved December 21, 2023, from https://floradobrasil.jbrj.gov.br/FB10945with ovoid to subglobose rhizomes.Wiersema, J. H. (1987). A monograph of Nymphaea subgenus Hydrocallis (Nymphaeaceae). Systematic Botany Monographs, 1-112. The ovate,suborbicular to orbicular floating leaves have flat, entire margins. The glabrous petiole has 2-4 primary central and 4-10 secondary peripheral air canals.de Lima, C. T., Machado, I. C., & Giulietti, A. M. (2021).

=Generative characteristics=
The glabrous, reddish peduncle has 5-6 primary central and 10−12 secondary peripheral air canals. The ovoid, ruminate, pilose seeds have trichomes arranged in continuous longitudinal lines.
It is only slightly fragrant. The floral fragrance has been described as solvent-like. It consists of the compounds Benzyl alcohol, and (methoxymethyl)benzene.Maia, A. C. D., de Lima, C. T., Navarro, D. M. D. A. F., Chartier, M., Giulietti, A. M., & Machado, I. C. (2014).

Cytology
Reproduction
=Vegetative reproduction=
It is stoloniferous, but does not produce proliferating pseudanthia. Vegetative reproduction does occur, but according to Wiersema, sexual reproduction likely is of greater significance in this species. However, more recent field observations indicate a greater significance of vegetative reproduction, which diminishes the importance of sexual reproduction.
=Generative reproduction=
Abundant seed production through autogamy has been reported. According to Wiersema, the main mode of reproduction in Nymphaea lingulata likely relies on autogamous sexual reproduction. Field observations contradict these findings, stating that the main mode of reproduction relies on stolon formation.
Taxonomy
It was first described by Wiersema in 1984.
