Terminology
Rhizomatous Aquatic Herbs: This term describes a plant that lives in water and has a horizontal, underground stem (rhizome). The rhizome can produce new shoots and roots, allowing the plant to spread. Nymphaeaceae: This is the botanical family to which Nymphaea nouchali belongs. It is commonly known as the water lily family, which includes other species like the white water lily. Petioles: These are the stalks that attach the leaf blade to the plant's stem. In Nymphaea nouchali, they are described as cylindrical and hairless. Stamens: These are the pollen-producing male parts of the flower. In this plant, they are numerous and yellow. Ovary: The female reproductive part of the flower, which holds the ovules and develops into the fruit. Ciliate on ribs: This refers to the fine, hair-like fringes on the ridges of the seeds, which become smooth as the aril (a fleshy seed covering) develops.
Availability
Nymphaea nouchali is a widely distributed plant, native to a large region stretching from tropical and subtropical Africa, across the Indian subcontinent, and into Southeast Asia and Australia. It is found in various static or slow-flowing freshwater habitats, such as ponds, lakes, and slow-moving rivers. Due to its ornamental value, it is also widely cultivated in water gardens and ponds in tropical and subtropical regions around the world. While it's common in its native range, ecological changes and human activities have impacted some populations. For example, the N. nouchali var. caerulea, or blue Egyptian lotus, has become rare in its native habitat along the Nile due to the construction of the Aswan Dam.
External Look
The plant is an aquatic perennial that grows from a tuberous rhizome. Its leaves are floating, elliptic, or nearly circular with a deep cut at the base where the petiole attaches. The upper surface of the leaves is green and smooth, while the underside is often reddish-purple. The leaf margins are wavy or slightly toothed. The flowers are the most striking feature, measuring 6-14 cm across. They are typically blue or mauve, but can also be pinkish or white, and are slightly fragrant. The flower consists of four green sepals and 8-15 elliptical-lance-shaped petals. The stamens are bright yellow, adding to the flower's vibrant appearance. The flowers are usually held erect above the water's surface on a fleshy stalk. After flowering, the sepals close up, and the fruit sinks back under the water to mature.
