Reference excerpt

Uvariopsis zenkeri Engl. is a species of flowering shrub in the family Annonaceae endemic to Cameroon and the Central African Republic.

Description Uvariopsis zenkeri is a shrub of 1–4 m high and bears its monoecious inflorescences on the old wood of both its branches and its trunk. Its petals are joined at the base of the flower.

Etymology The specific epithet zenkeri honours the German botanist Georg August Zenker, who discovered the first specimen at Bipindi in the Cameroons in 1896.

Distribution This species is found in shadow on laterite at an elevation of 120 m in Cameroon, and in the fringing forest of the rain-forest in the Central African Republic. IUCN, however, lists this species as endemic to Cameroon.

Taxonomy This plant was first described by Engler in 1899, and is the type species of Uvariopsis.

Worked examples

Example 1 — a first encounter with Uvariopsis zenkeri

Start with the simplest possible case. Write down what Uvariopsis zenkeri 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 Uvariopsis zenkeri 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 Uvariopsis zenkeri 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 Uvariopsis zenkeri

In research: Uvariopsis zenkeri 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 Uvariopsis zenkeri 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: Uvariopsis zenkeri is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cauliflory, Flora of Cameroon, IUCN Red List vulnerable species, so understanding it makes those chapters shorter.
In everyday life: Look for Uvariopsis zenkeri 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.
