Olfersia (plant)

Olfersia (plant) 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 Olfersia (plant) rather than just read about it. In short: Olfersia is a genus of ferns in the family Dryopteridaceae, subfamily Polybotryoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). They are found in Mexico and parts of South America.

Key takeaways

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

Reference excerpt

Olfersia is a genus of ferns in the family Dryopteridaceae, subfamily Polybotryoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). They are found in Mexico and parts of South America. The genus name of Olfersia is in honour of Ignaz Franz Werner Maria von Olfers (1793–1871), who was a German naturalist, historian and diplomat. The genus was circumscribed by Giuseppe Raddi in Opusc. Sci. vol.3 on page 283 in 1819.

Species As of January 2020, the Checklist of Ferns and Lycophytes of the World accepted the following species:

Olfersia alata C.Sánchez & Caluff Olfersia cervina (L.) Kunze Olfersia macrostegia (Hook.) comb. ined. Olfersia ochropteroides (Baker) comb. ined. As of August 2022, Plants of the World Online only accepts Olfersia alata C.Sánchez & Caluff and Olfersia cervina (L.) Kunze

Native They are found in Belize, Bolivia, Brazil, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, French Guiana, Guatemala, Guyana, Haiti, Honduras, Jamaica, Leeward Islands, Mexico, Nicaragua, Panamá, Peru, Puerto Rico, Suriname, Venezuela, Venezuelan Antilles and the Windward Islands.

Worked examples

Example 1 — a first encounter with Olfersia (plant)

Start with the simplest possible case. Write down what Olfersia (plant) 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 Olfersia (plant) 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 Olfersia (plant) 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 Olfersia (plant)

In research: Olfersia (plant) 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 Olfersia (plant) 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: Olfersia (plant) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dryopteridaceae, Dryopteridaceae stubs, Fern genera, so understanding it makes those chapters shorter.
In everyday life: Look for Olfersia (plant) 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.
