Tutu (plant)

Tutu (plant) is a science 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 Tutu (plant) rather than just read about it. In short: Tutu is a common name of Māori origin for plants in the genus Coriaria found in New Zealand. Name The Māori language name tutu has cognates found in other Eastern Polynesian languages such as Tahitian and Cook Islands Māori which use the word to describe Colubrina asiatica, a plant that has visual similarity to Coriaria.

Key takeaways

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

Reference excerpt

Tutu is a common name of Māori origin for plants in the genus Coriaria found in New Zealand.

Name The Māori language name tutu has cognates found in other Eastern Polynesian languages such as Tahitian and Cook Islands Māori which use the word to describe Colubrina asiatica, a plant that has visual similarity to Coriaria. Tutu is also colloquially known as toot in New Zealand.

Taxonomy

Eight New Zealand native species are known by the name:

Coriaria angustissima Coriaria arborea Coriaria kingiana Coriaria lurida Coriaria plumosa Coriaria pottsiana Coriaria pteridoides Coriaria sarmentosa

Description They are shrubs or trees; some are endemic to New Zealand. Most of the plant parts are poisonous, containing the neurotoxin tutin and its derivative hyenanchin.

Toxicity The widespread species Coriaria arborea is most often linked to cases of poisoning. Most of the plant except for the flesh of the fruit is toxic, including the seeds found within the fruit. Ingesting tutu berries was linked with many deaths of children during the early European settlement of New Zealand, as well as livestock deaths. Honey containing tutin can be produced by honey bees feeding on honeydew produced by sap-sucking vine hopper insects (genus Scolypopa) feeding on tutu. The last recorded deaths from eating honey containing tutin were in the 1890s, although sporadic outbreaks of toxic honey poisoning continue to occur. Poisoning symptoms include delirium, vomiting, and coma.

Food, medical and musical uses Tutu has a variety of food, medical and musical uses in traditional Māori culture. The berries were carefully filtered to remove the seeds to create waitutu, one of the few pre-European beverages in New Zealand. After European contact, tutu wine became a drink popular with many missionaries. In rongoā Māori traditional medicinal practices, the filtered juice was used as a laxative. Wood from large tutu trees was on occasion used to make kōauau flutes. Playing these instruments would cause the player to be mildly poisoned. This application of the poison may have been an intentional effect to create a spiritual or heightened experience.

Worked examples

Example 1 — a first encounter with Tutu (plant)

Start with the simplest possible case. Write down what Tutu (plant) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Tutu (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 Tutu (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 Tutu (plant)

In research: Tutu (plant) appears in science 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 Tutu (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: Tutu (plant) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coriariaceae, Cucurbitales stubs, Flora of New Zealand, so understanding it makes those chapters shorter.
In everyday life: Look for Tutu (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.
