Reference excerpt

Nymphaea subg. Lotos is a subgenus of the genus Nymphaea.

Description

Vegetative characteristics The rhizomes are short, vertical, and tuberous. The pubescent leaves have a dentate crenate, or serrate margin.

Generative characteristics The blue, white, cream, yellow, magenta, or pink, nocturnal or diurnal, emergent flowers extend up to 20 cm above the water surface. The stamens do not have sterile appendages at the apex.

Cytology In Nymphaea pubescens and Nymphaea lotus, the chromosome count is 2n = 56. They are tetraploid species.

Taxonomy

Publication It was published as Nymphaea sect. Lotos DC. by Augustin Pyramus de Candolle in 1821. Later, it was elevated to the subgenus Nymphaea subgen. Lotos (DC.) Conard published by Henry Shoemaker Conard in 1905.

Type species The type species is Nymphaea lotus L.

Species

Fossil record Fossils from the upper Oligocene (28.4–23.0 million years ago) of France have been assigned to Nymphaea subg. Lotos. It is also known from the Rupelian (33.9 – 27.82 Ma) of Bad Häring, Austria.

Distribution It is native to the paleotropis.

Ecology

Pollination Beetle pollination by Ruteloryctes morio has been reported in Nymphaea subg. Lotos.

Worked examples

Example 1 — a first encounter with Nymphaea subg. Lotos

Start with the simplest possible case. Write down what Nymphaea subg. Lotos 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 subg. Lotos 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 subg. Lotos 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 subg. Lotos

In research: Nymphaea subg. Lotos 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 subg. Lotos 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 subg. Lotos is common in secondary-school and first-year university syllabi. It links to neighbouring topics Nymphaea, Plant subgenera, so understanding it makes those chapters shorter.
In everyday life: Look for Nymphaea subg. Lotos 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.
