Nymphaea ampla

White Water Lily / Dotora

(Salisb.) DC., 1821

Detailed Texts Multi-lang
Nymphaea ampla is a rooted, perennial aquatic plant, famous for its mystical beauty and central role in the cosmogony of Mesoamerican civilizations. It possesses robust rhizomes submerged in the mud of freshwater bodies. Its leaves are large, orbicular, and floating, bright green on the upper side and often reddish or purple on the underside, with markedly serrated margins and a deep basal incision. The flower is spectacular: it emerges above the water surface held by a long peduncle, with immaculate white petals surrounding a center of intense yellow stamens. The flowers open during the day and exhale a sweet, heady fragrance that attracts beetles and bees. The fruit ripens underwater, releasing seeds that are dispersed by currents. It is an architectural species that transforms the surface of lagoons and swamps into vibrant ecosystems.

Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

It inhabits slow-moving or stagnant freshwater bodies such as lagoons, swamps, canals, and river backwaters. It prefers shallow waters (up to 2 meters deep) with muddy bottoms rich in organic matter and full sun exposure. In Costa Rica, it is an iconic species of lowland wetlands, being especially abundant in Palo Verde National Park, Caño Negro, and coastal lagoons on both slopes.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

It is a structural species that acts as the foundation of aquatic micro-ecosystems. Its floating leaves provide shade that regulates water temperature and offers refuge for fish, amphibians, and invertebrates. Its flowers are pollinated by beetles from the Scarabaeidae family, which often spend the night inside the closed flower. The plant exhibits nyctinastic behavior, opening its flowers at dawn and closing them at dusk.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

Aerenchyma and Buoyancy: Its petioles and peduncles have a specialized tissue called aerenchyma, filled with air channels. This adaptation not only allows leaves and flowers to float effortlessly but also facilitates oxygen transport from the surface to the rhizomes submerged in anoxic mud.
Hydrophobic Cuticular Layer: The upper surface of the leaves is covered by a dense waxy layer that repels water (lotus effect). This prevents the stomata, located only on the top side, from being blocked by water, allowing uninterrupted photosynthesis.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Agrochemical pollution: Inhabiting wetlands surrounded by agriculture, it is vulnerable to eutrophication and herbicides draining into water bodies, altering its reproductive cycle.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

The Sacred Flower of the Mayas: The ancient Mayas considered it a symbol of creation and rebirth. It was frequently depicted in art, and its flowers are believed to contain alkaloid compounds with psychoactive properties used in shamanic rituals.
