Reference excerpt

Nymphaea jacobsii subsp. toomba is a subspecies of Nymphaea jacobsii endemic to Queensland, Australia.

Description

Vegetative characteristics Nymphaea jacobsii subsp. toomba is a rhizomatous, annual or perennial herb with a globose to elongate, up to 25 cm long rhizome. The suborbicular to broadly elliptic, petiolate, stipulate leaf with a finely dentate margin is 29–75 cm long, and 27–35 cm wide.

Generative characteristics The relatively smaller, blue flowers have green, 4.2–8.5 cm long, and 4.2–6.0 cm wide sepals with an obtuse apex. The 12–20 lanceolate, white and blue petals with an acute apex are 5–8.5 cm long, and 2.5–4 cm wide. The androecium consists of 150–300 yellow stamens. The gynoecium consists of 12–25 carpels. The globose, (2.5–)4–7 cm wide fruit bears large, hairy, ovoid, 2.6–5(–6) mm long, and 2–3 mm wide seeds.

Taxonomy It was described by Carl Barre Hellquist in 2011. The type specimen was collected by S. Jacobs and C. B. Hellquist in 'Toomba' Creek, North Kennedy, Queensland, Australia on the 11th of June 2007. It is placed in the subgenus Nymphaea subg. Anecphya.

Etymology The subspecific epithet toomba refers to "Toomba", the property of Ernest and Robyn Bassingthwaighte, and honours their friendship with Hellquist.

Distribution It is endemic to Queensland, Australia.

Worked examples

Example 1 — a first encounter with Nymphaea jacobsii subsp. toomba

Start with the simplest possible case. Write down what Nymphaea jacobsii subsp. toomba 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 jacobsii subsp. toomba 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 jacobsii subsp. toomba 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 jacobsii subsp. toomba

In research: Nymphaea jacobsii subsp. toomba 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 jacobsii subsp. toomba 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 jacobsii subsp. toomba is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of Australia, Flora of Queensland, Nymphaea, so understanding it makes those chapters shorter.
In everyday life: Look for Nymphaea jacobsii subsp. toomba 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.
