Nymphaea odorata

Nymphaea odorata is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nymphaea odorata rather than just read about it. In short: Nymphaea odorata, also known as the American white waterlily, fragrant water-lily, beaver root, fragrant white water lily, white water lily, sweet-scented white water lily, and sweet-scented water lily, is an aquatic plant belonging to the genus Nymphaea. It can commonly be found in shallow lakes, ponds, and permanent slow moving waters throughout North America where it ranges from Central America to northern Canada.

Key takeaways

Nymphaea odorata belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nymphaea odorata to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nymphaea odorata from memory before moving on to harder problems.

Reference excerpt

Nymphaea odorata, also known as the American white waterlily, fragrant water-lily, beaver root, fragrant white water lily, white water lily, sweet-scented white water lily, and sweet-scented water lily, is an aquatic plant belonging to the genus Nymphaea. It can commonly be found in shallow lakes, ponds, and permanent slow moving waters throughout North America where it ranges from Central America to northern Canada. It is also reported from Brazil and Guyana.

Description This plant is rooted from branched rhizomes that gives rise to long petioles that terminate in smooth floating leaves. The flowers float as well. They are radially symmetric with prominent yellow stamens and many white petals. The flowers open each day and close again each night and are very fragrant. Once the flowers are pollinated, the developing fruit is pulled back under water for maturation.

Cytology The chromosome count is n = 28 or n = 56. The genome size is 1574.58 Mb.

Chemistry The lignans nymphaeoside A and icariside E, and the flavonols kaempferol 3-O-alpha-l-rhamnopyranoside (afzelin), quercetin 3-O-alpha-l-rhamnopyranoside (quercitrin), myricetin 3-O-alpha-l-rhamnopyranoside (myricitrin), quercetin 3-O-(6'-O-acetyl)-beta-d-galactopyranoside, myricetin 3-O-beta-d-galactopyranoside and myricetin 3-O-(6'-O-acetyl)-beta-d-galactopyranoside can be found in N. odorata.

Taxonomy

Subspecies It is divided into two subspecies:

Nymphaea odorata subsp. odorata Nymphaea odorata subsp. tuberosa (Paine) Wiersema & Hellq.

Uses The fragrant water-lily has both medical and edible parts. The seeds, flowers and rhizomes can all be eaten raw or cooked. The root can be boiled to produce a liquid which can be gargled to treat sore throats or drunk to treat diarrhea. The rhizomes were also used by Native Americans to treat coughs and colds. The stem can be placed directly on teeth to treat a toothache. The muck-submerged stems are eaten by muskrats.

Worked examples

Example 1 — a first encounter with Nymphaea odorata

Start with the simplest possible case. Write down what Nymphaea odorata claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nymphaea odorata before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nymphaea odorata ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nymphaea odorata

In research: Nymphaea odorata appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nymphaea odorata in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nymphaea odorata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of Northern America, Flora of Southern America, Freshwater plants, so understanding it makes those chapters shorter.
In everyday life: Look for Nymphaea odorata outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
