Reference excerpt

Hakea recurva subsp. recurva is a plant in the family Proteaceae endemic to the south-west of Western Australia.

Description A multi-stemmed tall shrub or open tree to 7 m (20 ft) high. Leaves are terete thick, rigid, straight and erect or recurved, 5–12 cm (2–5 in) long and 2–3.2 mm (0.08–0.1 in) wide ending in a very sharp point 3.7–5.5 mm (0.1–0.2 in) long. Large sweetly scented creamy-yellow or occasionally pink flowers appear in profusion in clusters in the leaf axils. Egg-shaped fruit 1.5–2.5 cm (0.6–1 in) long by 1–1.3 cm (0.4–0.5 in) wide taper to a blunt beak. Hakea recurva subsp. recurva sheds its seed quickly upon ripening.

Taxonomy and naming Hakea recurva was first formally described in 1856 by Carl Meissner and Hakea arida in 1904 by Ludwig Diels. In 1999 William and Robyn Barker came to the conclusion that these two species were in fact too much alike to be in separate species. They changed the name Hakea recurva to Hakea recurva subsp. recurva and changed Hakea arida to Hakea recurva subsp. arida. The changes were published on pages 85–87 of Volume 17B of the Flora of Australia.

Distribution and habitat This species is found north of Perth from the Murchison River through the central wheatbelt region of Western Australia to Kulin and east to Coolgardie. Grows in heath and low woodland on sandy clay over granite or laterite, loam and gravel. A frost tolerant species, requiring full sun and good drainage.

Worked examples

Example 1 — a first encounter with Hakea recurva subsp. recurva

Start with the simplest possible case. Write down what Hakea recurva subsp. recurva 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 Hakea recurva subsp. recurva 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 Hakea recurva subsp. recurva 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 Hakea recurva subsp. recurva

In research: Hakea recurva subsp. recurva 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 Hakea recurva subsp. recurva 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: Hakea recurva subsp. recurva is common in secondary-school and first-year university syllabi. It links to neighbouring topics Eudicots of Western Australia, Hakea, Plant subspecies, so understanding it makes those chapters shorter.
In everyday life: Look for Hakea recurva subsp. recurva 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.
