Reference excerpt

Nuphar oguraensis is a species of rhizomatous aquatic plant endemic to Japan.

Description

Vegetative characteristics The petiolate, green, ovate floating leaves are 7.5-11.5 cm long, and 6-9 cm wide. The petiole is 1-3 mm wide. The petiole is semi-hollow.

Generative characteristics The flowers are 1.7-2.5 cm wide. The 2.5-3 cm long, and 1.5-2 cm wide fruit bears brown, 3.5-4 mm long, and 2.5 mm wide seeds.

Reproduction

Generative reproduction Flowering occurs from June to October.

Taxonomy

Publication It was first described by Shigeru Miki in 1934.

Type specimen The lectotype is an illustration of this species in the original publication by Shigeru Miki.

Natural hybridisation It has been speculated to be of hybrid origin involving Nuphar pumila and Nuphar japonica.

Conservation It is threatened by urbanisation and land development. It is regarded as a vulnerable species.

Ecology

Habitat It occurs in rivers, lakes, ponds, and ditches.

Worked examples

Example 1 — a first encounter with Nuphar oguraensis

Start with the simplest possible case. Write down what Nuphar oguraensis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Nuphar oguraensis 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 Nuphar oguraensis 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 Nuphar oguraensis

In research: Nuphar oguraensis appears in science 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 Nuphar oguraensis 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: Nuphar oguraensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Angiosperm stubs, Endemic flora of Japan, Flora of Japan, so understanding it makes those chapters shorter.
In everyday life: Look for Nuphar oguraensis 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.
