Description The tree is small and has a dense crown.

Key takeaways

Ulmus laevis var. parvifolia 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 laevis var. parvifolia to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Ulmus laevis var. parvifolia from memory before moving on to harder problems.

Reference excerpt

Ulmus laevis var. parvifolia is a mutant variety of European white elm found exclusively on the island of Ada Ciganlija, in the Sava at Belgrade, Serbia.

Description The tree is small and has a dense crown. The leaves are much smaller than those of the species, 21 – 59 mm (average 40 mm) in length by 14 – 36 mm (average 26 mm) width, and chartreuse in colour. The specimen of var. parvifolia on Ada Ciganlija is very slow-growing, attaining a height of only 5.5 m in almost 60 years, with a d.b.h. of just 13 cm.

Pests and diseases Not known, but the species has a field resistance to Dutch elm disease, through the presence of a triterpene, Alnulin, in the bark which acts as an antifeedant to the vector Scolytus beetles.

Cultivation The tree is not known to have ever flowered, thus propagation is by cuttings only. The variety is not known to be in commerce in Serbia or elsewhere.

Worked examples

Example 1 — a first encounter with Ulmus laevis var. parvifolia

Start with the simplest possible case. Write down what Ulmus laevis var. parvifolia 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 laevis var. parvifolia 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 laevis var. parvifolia 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 laevis var. parvifolia

In research: Ulmus laevis var. parvifolia 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 laevis var. parvifolia 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 laevis var. parvifolia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Elm species and varieties, Flora of Serbia, Trees of Europe, so understanding it makes those chapters shorter.
In everyday life: Look for Ulmus laevis var. parvifolia 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.
