Reference excerpt

Nymphaea jamesoniana is a species of waterlily native to the USA (Western Florida), Mexico, and tropical South America.

Description

Vegetative characteristics Nymphaea jamesoniana is a long-lived, perennial aquatic herb. The abaxial leaf surface is marked with short, dark purple, sometimes bifurcating lines.

Generative characteristics The granulose, pilose, ellipsoid seeds feature trichomes in longitudinal, interrupted lines.

Cytology The diploid chromosome count is 2n = 28. The chloroplast genome is 158830 bp long.

Reproduction

Vegetative reproduction Stolons and proliferating pseudanthia are absent.

Generative reproduction Water disperses the seeds (i.e. hydrochory).

Habitat It grows in various freshwater habitats, such as marshes, canals, shallow waters, flooded ditches, flooded flatwoods, ponds, slowly flowing streams, and lakes. It is intolerant of saltwater.

Taxonomy Nymphaea jamesoniana was first published by Jules Émile Planchon in 1852.

Type specimen The type specimen was collected in Ecuador by Jameson.

Placement within Nymphaea It is placed in Nymphaea subg. Hydrocallis.

Etymology The specific epithet jamesoniana honours the Scottish botanist William Jameson (1796-1873).

Conservation In Puerto Rico, USA it faces habitat destruction. The NatureServe conservation status is secure (G5). In Florida, USA it is considered to be endangered.

Uses Nymphaea jamesoniana has been employed in the treatment of conditions such as irritated eyes, dysentery, and skin lesions. It has been utilized for its astringent properties. There are claims that its flowers possess narcotic properties. The Chorote people of Argentina use the rhizomes as food. Apart from the Chorote people, the rhizomes are also used by Wichi, Western Toba, and Pilagá.

Cultivation It is suitable for cultivation in the USDA zones 9a - 10a.

Worked examples

Example 1 — a first encounter with Nymphaea jamesoniana

Start with the simplest possible case. Write down what Nymphaea jamesoniana 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 Nymphaea jamesoniana 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 jamesoniana 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 jamesoniana

In research: Nymphaea jamesoniana 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 Nymphaea jamesoniana 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 jamesoniana is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of Argentina, Flora of Bolivia, Flora of Brazil, so understanding it makes those chapters shorter.
In everyday life: Look for Nymphaea jamesoniana 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.
