Terpsichore (plant)

Terpsichore (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 Terpsichore (plant) rather than just read about it. In short: Terpsichore is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It is native to the Neotropical realm in the Americas.

Key takeaways

Terpsichore (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 Terpsichore (plant) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Terpsichore (plant) from memory before moving on to harder problems.

Reference excerpt

Terpsichore is a genus of ferns in the family Polypodiaceae, subfamily Grammitidoideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It is native to the Neotropical realm in the Americas.

Description The genus consists of small ferns with arching fronds of determinate size. Rhizomes are radially symmetric or slightly flattened, with orange to brown scales which often bear setulae (small bristles) on the edges and sometimes the surface. Except for Terpsichore atroviridis, sporangia bear setae (bristles). The stipe (leaf stalk) is distinct from the blade, and the blade does not taper gradually to its attachment to the rhizome. Setae on the leaf tissue are borne singly, rather than in clusters, and hydathodes (enlarged vein endings) do not secrete a chalk precipitate. Unlike Ascogrammitis and Mycopteris, black fungal fruiting bodies are not found on the leaf blades.

Taxonomy Terpsichore was first described by Alan R. Smith in 1993, one of several genera to be recognized to remove many Neotropical grammitids from the genus Grammitis. The name, originally applied to some members of the group by L. Earl Bishop, but not published by him, honors Terpsichore, the muse of dance. Subsequent phylogenetic analyses showed that Terpsichore, as originally described, was polyphyletic. Five new genera, Alansmia, Galactodenia, Moranopteris, Ascogrammitis, and Mycopteris were recognized in order to accommodate most of the species in the genus; the species from only one of Smith's five informal infrageneric groups, the Terpsichore asplenifolia group, remain in Terpsichore as presently circumscribed.

Species As of October 2025, the Checklist of Ferns and Lycophytes of the World accepted the following sixteen species:

Terpsichore alfaroi (Donn. Sm.) A.R.Sm. Terpsichore alsophilicola (Christ) A.R.Sm. Terpsichore asplenifolia (L.) A.R.Sm. Terpsichore atroviridis (Copel.) A.R.Sm. Terpsichore bipinnata (Stolze) A.R.Sm. Terpsichore chrysleri (Copel.) A.R.Sm. Terpsichore dolorensis (Hieron.) A.R.Sm. Terpsichore eggersii (Baker ex Hook.) A.R.Sm. Terpsichore exornans (Maxon) A.R.Sm. Terpsichore flexuosa (Maxon) A.R.Sm. Terpsichore haenkeana (Proctor) A.R.Sm. Terpsichore jenmanii (Underw. ex Maxon) A.R.Sm. Terpsichore lehmanniana (Hieron.) A.R.Sm. Terpsichore liogieri (Proctor) A.R.Sm. Terpsichore paulistana (Brade & Rosenst.) A.R.Sm. Terpsichore staheliana (Posth.) A.R.Sm.

Worked examples

Example 1 — a first encounter with Terpsichore (plant)

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

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