Ulmus wallichiana subsp. wallichiana

Ulmus wallichiana subsp. wallichiana is a biology 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 Ulmus wallichiana subsp. wallichiana rather than just read about it. In short: Ulmus wallichiana subsp. wallichiana was identified by Melville and Heybroek after the latter's expedition to the Himalaya in 1960. Description A deciduous tree growing to 30 m with a crown comprising several ascending branches.

Key takeaways

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

Reference excerpt

Ulmus wallichiana subsp. wallichiana was identified by Melville and Heybroek after the latter's expedition to the Himalaya in 1960.

Description A deciduous tree growing to 30 m with a crown comprising several ascending branches. The bark of the trunk is grey-brown, furrowed longitudinally. The leaves range from 6–13 cm long by 2.5–6 cm broad, elliptic-acuminate in shape, and with a glabrous upper surface, on petioles 5–10 mm long. The samarae are orbicular to obovate, 10–13 mm in diameter, on 5 mm pedicels, the seed central.

Pests and diseases The tree has a high resistance to the fungus Ophiostoma himal-ulmi endemic to the Himalayas and the cause of Dutch elm disease there.

Cultivation The tree is not known to be in cultivation beyond the Himalaya.

Worked examples

Example 1 — a first encounter with Ulmus wallichiana subsp. wallichiana

Start with the simplest possible case. Write down what Ulmus wallichiana subsp. wallichiana 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 Ulmus wallichiana subsp. wallichiana 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 Ulmus wallichiana subsp. wallichiana 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 Ulmus wallichiana subsp. wallichiana

In research: Ulmus wallichiana subsp. wallichiana 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 Ulmus wallichiana subsp. wallichiana 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: Ulmus wallichiana subsp. wallichiana is common in secondary-school and first-year university syllabi. It links to neighbouring topics Elm species and varieties, Flora of West Himalaya, Plant subspecies, so understanding it makes those chapters shorter.
In everyday life: Look for Ulmus wallichiana subsp. wallichiana 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.
