Reference excerpt

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

Description An erect dense shrub 1.7–5 m (6–20 ft) high with smooth to rough grey bark. Terete dark green leaves are thick and rigid 2.5–4 cm (1–2 in) long and 1.2–1.6 mm (0.05–0.06 in) wide ending with a very sharp point 2.8–4.5 mm (0.1–0.2 in) long. They may be straight or have an upward curve. Profuse white-cream fragrant flowers appear in dense clusters in the leaf axils. The fruit are 0.7–1 cm (0.3–0.4 in) wide, egg-shaped with a smooth to slightly rough surface ending with a small pointed beak.

Taxonomy and naming This hakea was first formally described in 1904 by Ludwig Diels who gave it the name Hakea arida and published the description in Botanische Jahrbücher für Systematik, Pflanzengeschichte und Pflanzengeographie. In 1999, William Barker and Robyn Barker changed the name to Hakea recurva subsp. arida. Named from the Latin aridus 'dry', referring to the semi-arid area where it grows.

Distribution and habitat Grows inland from Mount Augustus south to Wubin on sandstone slopes, river banks, flats in sand, loam and stony soils with quartzite and laterite. An ornamental frost tolerant species requiring full sun and good drainage. A good habitat plant for wildlife due to its dense prickly growth habit.

Conservation status Hakea recurva subsp. arida is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.

Worked examples

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

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

In research: Hakea recurva subsp. arida 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. arida 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. arida 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. arida 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.
