Lomagramma

Lomagramma 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 Lomagramma rather than just read about it. In short: Lomagramma is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy Lomagramma was first described by John Smith in 1841.

Key takeaways

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

Reference excerpt

Lomagramma is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).

Taxonomy Lomagramma was first described by John Smith in 1841. The genus is recognized in the PPG I classification, and, As of January 2020, by the Checklist of Ferns and Lycophytes of the World and Plants of the World Online. It has been proposed that the genus should be merged into Bolbitis.

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

Lomagramma angustipinna Copel. Lomagramma brassii Holttum Lomagramma brooksii Copel. Lomagramma copelandii Holttum Lomagramma cordipinna Holttum Lomagramma cultrata (Baker) Holttum Lomagramma leucolepis Holttum Lomagramma lomarioides (Blume) J.Sm. Lomagramma melanolepis Alderw. Lomagramma merrillii Holttum Lomagramma novoguineensis (Brause) C.Chr. Lomagramma perakensis Bedd. Lomagramma polyphylla Brack. Lomagramma pteroides J.Sm. Lomagramma sinuata C.Chr. Lomagramma sorbifolia (Willd.) Ching Lomagramma sumatrana Alderw. Lomagramma tahitensis Holttum

Worked examples

Example 1 — a first encounter with Lomagramma

Start with the simplest possible case. Write down what Lomagramma 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 Lomagramma 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 Lomagramma 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 Lomagramma

In research: Lomagramma 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 Lomagramma 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: Lomagramma 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 Lomagramma 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.

Frequently asked questions

What is Lomagramma in simple terms?

Lomagramma is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy Lomagramma was first described by John Smith in 1841.

Why does Lomagramma matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lomagramma?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
