Nymphaea lingulata is a species of waterlily native to Bolivia, Brazil, and Paraguay.
Description
Vegetative characteristics
Nymphaea lingulata is an aquatic herbwith ovoid to subglobose rhizomes. 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.
Taxonomy
It was first described by Wiersema in 1984.
Type specimen
The type specimen of was collected by Wiersema, Horn, and de Ataide Silva in Maranhão, Brazil, from a pond between Teresina and Caxias on the 28th of June 1982.
Placement within Nymphaea
It is placed in Nymphaea subg. Hydrocallis.
Etymology
The specific epithet lingulata means tongue-shaped.
Conservation
It appears to be a rare species.
Ecology
Habitat
Nymphaea lingulata grows in temporary lagoons, and in slowly flowing rivers. It occurs sympatrically with Nymphaea pulchella, and Cabomba.
Pollination
Scarab beetles likely act as pollinators of Nymphaea lingulata.
