Utricularia campbelliana

Utricularia campbelliana 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 Utricularia campbelliana rather than just read about it. In short: Utricularia campbelliana is a small epiphytic, perennial carnivorous plant that belongs to the genus Utricularia. U. campbelliana is endemic to northern South America, where it is found in Guyana and Venezuela and most likely also Brazil, though no positive records exist from that country.

Key takeaways

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

Reference excerpt

Utricularia campbelliana is a small epiphytic, perennial carnivorous plant that belongs to the genus Utricularia. U. campbelliana is endemic to northern South America, where it is found in Guyana and Venezuela and most likely also Brazil, though no positive records exist from that country. It was originally published and described by Daniel Oliver in 1887. It is named in honor of William Hunter Campbell, an attorney and amateur botanist who lived in Georgetown, Guyana. Its habitat is reported as being tree trunks, branches, and prop roots (mostly of Bonnetia species) at altitudes from 1,500 metres (4,921 ft) to 2,500 metres (8,202 ft), but has been found at altitudes as low as 690 metres (2,264 ft). It has been seen flowering between August and April. In his 1989 monograph on the genus, Peter Taylor noted that at least one specimen has been recorded as being visited by a hummingbird and it is likely that both U. campbelliana and U. quelchii are bird-pollinated.

Worked examples

Example 1 — a first encounter with Utricularia campbelliana

Start with the simplest possible case. Write down what Utricularia campbelliana 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 Utricularia campbelliana 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 Utricularia campbelliana 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 Utricularia campbelliana

In research: Utricularia campbelliana 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 Utricularia campbelliana 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: Utricularia campbelliana is common in secondary-school and first-year university syllabi. It links to neighbouring topics Carnivorous plants of South America, Epiphytes, Flora of Guyana, so understanding it makes those chapters shorter.
In everyday life: Look for Utricularia campbelliana 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.
