[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.

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.

Cytology
The diploid chromosome count is 2n = 18.
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.
