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 subgenus 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]
