Myrceugenia planipes

Myrceugenia planipes is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Myrceugenia planipes rather than just read about it. In short: Myrceugenia planipes, known as Valdivia's patagua (Patagua de Valdivia) is an evergreen found in Chile and Argentina from 37 to 45°S. It occurs between 400 (1300) and 700 m (2300 ft) above sea level.

Key takeaways

Myrceugenia planipes belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Myrceugenia planipes to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Myrceugenia planipes from memory before moving on to harder problems.

Reference excerpt

Myrceugenia planipes, known as Valdivia's patagua (Patagua de Valdivia) is an evergreen found in Chile and Argentina from 37 to 45°S. It occurs between 400 (1300) and 700 m (2300 ft) above sea level.

Description It is an evergreen small tree or shrub that measures up to 8 m (26 ft) tall, smooth grey bark, young shoots are densely hairy, opposite and elliptical leaves with the entire margin, acuminate apex and wedge-shaped to acuminate base. The leaves are 2.2–8 cm long and 1.3 cm wide, glossy green and glabrous above and pale green and hairy below when young. Petioles are fluted 2–6 mm long. Midrib prominent underside. The flowers are hermaphrodite, solitary and axillary or clustered in axillary inflorescences in groups of 2-3 flowers, 4 sepals fused at the base and 4 with free falling white petals . The stamens are very numerous: they vary 120-220 and 7–12 mm long, a style about 5–8 mm long. The fruit is a black sub-globose berry, about 0.8–1 cm diameter . Within it there are 3-4 seeds about 4–5 mm long.

Uses It is used in popular medicine as remedy for skin diseases.

Etymology It is the fusion of the names of the genera Myrcia and Eugenia. It has been planted in Spain.

Worked examples

Example 1 — a first encounter with Myrceugenia planipes

Start with the simplest possible case. Write down what Myrceugenia planipes claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Myrceugenia planipes 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 Myrceugenia planipes 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 Myrceugenia planipes

In research: Myrceugenia planipes appears in earth 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 Myrceugenia planipes 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: Myrceugenia planipes is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of the Valdivian temperate forests, Myrceugenia, Trees of Argentina, so understanding it makes those chapters shorter.
In everyday life: Look for Myrceugenia planipes 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.
