Reference excerpt

Weinmannia trichosperma, the tineo, is an evergreen tree in the family of Cunoniaceae, it is native to Chile and Argentina: 35 to 47°S. endemic to laurel forest habitat.

Description Weinmannia trichosperma grows up to 30 m (100 ft) high. It has a straight trunk up to 1 m (3 ft) in diameter and gray, fissured bark. The leaves are imparipinnate and opposite. Between the leaflets there are triangular wings giving each pair a rhomboid outline. There are two deciduous stipules at the base of the leaves. The leaves are about 3–8 cm long and 2–4 cm wide, and the leaflets are 0.6–1.6 cm long and 0.6–1.0 cm wide and toothed. The foliage tends to be sparse and spread out. The flowers are hermaphrodite, small, white and clustered in racemes. The calyx is made up of 4–5 imbricate sepals; the corolla has 3–5 composite petals; the androecium has 8-10 stamens; the gynoecium has a superior ovary with 2 carpels and white stigmas. The fruit is a leathery obovate capsule which is divided in two. In autumn the capsule turns bright red, and is 6–9 mm long and 2 mm wide. It opens in the middle between the styles. The seeds are ellipsoid, light brown, with scattered white hairs and small: 1 mm long and 0.6 mm wide.

Cultivation and uses The bark can be used to tan leather. W. trichosperma is used as an ornamental tree in Chile. The flowers are used by introduced European bees to make a delicious honey. The wood is hard and exhibits a vivid grain pattern of darker and lighter colouration, making it highly prized for decorative uses. It thrives in cool and moist climates, and it succeeds as an ornamental in Northern Ireland, Scotland, some parts of England and in the North Pacific Coast of the United States.

Veneers Weinmannia trichosperma species gives a valuable veneer, called Tineo in the Latin American trade. It is valued as a decorative veneer for its warm reddish-brown to pinkish tones, often accompanied by a fine, uniform texture and a generally straight to slightly interlocked grain. When sliced into veneer, Tineo can show a calm, elegant figure with a natural satin-like sheen, making it well suited for refined interior applications such as wall paneling, cabinetry, furniture, and architectural joinery where a subtle but rich aesthetic is desired.

Etymology Weinmannia, for German botanist J. A. Weinmann (1782–1858); trichosperma, from Latin: hairy seeds. And tineo, Mapuche name.

Worked examples

Example 1 — a first encounter with Weinmannia trichosperma

Start with the simplest possible case. Write down what Weinmannia trichosperma 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 Weinmannia trichosperma 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 Weinmannia trichosperma 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 Weinmannia trichosperma

In research: Weinmannia trichosperma 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 Weinmannia trichosperma 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: Weinmannia trichosperma is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of central Chile, Flora of the Andes, Flora of the Valdivian temperate forests, so understanding it makes those chapters shorter.
In everyday life: Look for Weinmannia trichosperma 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.
