Nymphaea lingulata is a species of waterlily native to Bolivia, Brazil, and Paraguay.^[1]

Description

Vegetative characteristics

Nymphaea lingulata is an aquatic herb^[2]with ovoid to subglobose rhizomes.^[3] The ovate,suborbicular to orbicular floating leaves have flat, entire margins.^[2] The glabrous petiole has 2-4 primary central and 4-10 secondary peripheral air canals.^[4]

Generative characteristics

The glabrous, reddish peduncle has 5-6 primary central and 10−12 secondary peripheral air canals.^[4] The ovoid, ruminate, pilose seeds have trichomes arranged in continuous longitudinal lines.^[2]

It is only slightly fragrant.^[3] The floral fragrance has been described as solvent-like. It consists of the compounds Benzyl alcohol, and (methoxymethyl)benzene.^[5]

Cytology

The diploid chromosome count is 2n = 18.^[3]

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.^[3] However, more recent field observations indicate a greater significance of vegetative reproduction, which diminishes the importance of sexual reproduction.^[4]

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.^[3] Field observations contradict these findings, stating that the main mode of reproduction relies on stolon formation.^[4]

Taxonomy

It was first described by Wiersema in 1984.^[1]

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.^[3]

Placement within Nymphaea

It is placed in Nymphaea subg. Hydrocallis.^[3]

Etymology

The specific epithet lingulata means tongue-shaped.^[6]

Conservation

It appears to be a rare species.^[3]

Ecology

Habitat

Nymphaea lingulata grows in temporary lagoons, and in slowly flowing rivers. It occurs sympatrically with Nymphaea pulchella, and Cabomba.^[4]

Pollination

Scarab beetles likely act as pollinators of Nymphaea lingulata.^[4]
