Mentha canadensis

Mentha canadensis 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 Mentha canadensis rather than just read about it. In short: Mentha canadensis is a species of mint native to North America (from the Northwest Territories to central Mexico) and the eastern part of Asia (from Siberia to Java). In North America, it is commonly known as Canada mint, American wild mint, and in Asia as Chinese mint, Sakhalin mint, Japanese mint, and East Asian wild mint.

Key takeaways

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

Reference excerpt

Mentha canadensis is a species of mint native to North America (from the Northwest Territories to central Mexico) and the eastern part of Asia (from Siberia to Java). In North America, it is commonly known as Canada mint, American wild mint, and in Asia as Chinese mint, Sakhalin mint, Japanese mint, and East Asian wild mint. The flowers are bluish or have a slight violet tint. The plant is upright, growing to about 30–60 cm (12–24 in) tall. The leaves are opposite, and flower clusters appear in the upper leaf axils. This mint grows in wet areas but not directly in water, so it will be found near marshes, and lake and river edges. Plants bloom from July to August in their native habitats. Some populations found in eastern Asia have been distinguished as Mentha sachalinensis, but this is treated as a synonym of M. canadensis by the Plants of the World Online database.

Description

Mentha canadensis is a perennial plant with an underground creeping rhizome and upright, much-branched shoots. It can grow to a height of about 60 centimetres (24 in). It has finely hairy stems bearing opposite pairs of leaves. Each leaf is borne on a short stalk and has a wedge-shaped base and is lanceolate or ovate, with a toothed margin and a hairy surface. The flowers are borne in spikes at the tips of the shoots. The flowers may be bluish, pink or white. They are arranged in a spiral around the inflorescence. Each flower has five sepals, four petals, four stamens and a superior ovary. The fruit is dry, and splits open when ripe releasing the two seeds.

Taxonomy Mentha canadensis was first described by Carl Linnaeus in 1753. It has been described since under a large number of synonyms, including as varieties or subspecies of M. arvensis, some of which, such as M. arvensis var. sachalinensis Briq., were subsequently raised to the status of a full species. Thus the Flora of China, in a volume published in 1994, lists M. canadensis and M. sachalinensis as separate species, distinguishing them on the basis of features such as degree of branching, hairiness and leaf shape. More recent sources treat M. canadensis as a single variable species with many synonyms and a wide distribution in North America and eastern temperate and tropical Asia. Mentha canadensis is an amphidiploid with 2n = 96 chromosomes. It is believed to be derived from ancient hybridization between M. arvensis (2n = 72) and M. longifolia (2n = 24).

Distribution Mentha canadensis has been found as a native species of mint around the world. Below is a detailed list of countries and states in which Mentha canadensis is considered to be native. Asia (both temperate and tropical)

East Asia: China; Japan( Hokkaido, Honshu, Kyushu and Shikoku); Korea Russian Far East: Russian Federation (Kurile Islands, Khabarovsk, Primorye, Amur and Sakhalin) Siberia: Russian Federation (Buryatia, Tuva, Yakutia-Sakha, Krasnoyarsk, Chita and Irkutsk) Indian Subcontinent: India; Nepal; Sri Lanka Indo-China: Cambodia; Laos; Myanmar; Thailand; Vietnam Malesia: Indonesia; Malaysia; Philippines Northern America

Eastern Canada: Canada (Quebec, Nova Scotia, Ontario, Prince Edward Island, New Brunswick and Newfoundland) North-Central U.S.: United States (Illinois, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, Oklahoma, South Dakota, Wisconsin) Northeastern U.S.: United States (Connecticut, Indiana, Maine, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont and West Virginia) Northwestern U.S.: United States (Colorado, Idaho, Montana, Oregon, Washington and Wyoming) South-Central U.S.: United States (New Mexico and Texas) Southeastern U.S.: United States (Kentucky, Maryland, North Carolina, Tennessee and Virginia) Southwestern U.S.: United States (Arizona, California, Nevada, Utah) Subarctic America: Canada (Northwest Territory and Yukon); United States (Alaska) Western Canada: Canada (Saskatchewan, Alberta, Manitoba and British Columbia)

Cultivation Mentha canadensis is cultivated throughout the world:

Africa Angola, South Africa, Seychelles Asia China, Japan, Korea, Taiwan, India, Thailand, New Zealand North America Mexico, United States South America Brazil, Cuba, Argentina

Uses It is grown in Hungary for essential oil and menthol production. It also contains a significant amount of pulegone. The leaves have a distinct peppermint smell when pinched or crushed as the plant contains aromatic oils. The leaves can be picked at any time during plant growth, and may be dried. They are used in making mint jelly, mint tea, and mint leaf candy. First nations people use mint tea for bad breath or toothache, or to cure hiccups. The mint can also be used for fox or lynx bait. Mint essential oil is known to be effective as insect repellent for insects such as Drosophila melanogaster.

Medicinal uses One of the most important essential oils used in medicine is Japanese mint oil. Mentha canadensis is rich in natural menthol compared to other mint species, and menthol is used extensively in a number of pharmaceutical preparations. Approximately 4000 tons of Japanese mint oil and 2000 tons of menthol were produced in the world in 1998. The major producing countries are Brazil, Paraguay, Taiwan, Japan, China, India, and Thailand.

Worked examples

Example 1 — a first encounter with Mentha canadensis

Start with the simplest possible case. Write down what Mentha canadensis 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 Mentha canadensis 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 Mentha canadensis 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 Mentha canadensis

In research: Mentha canadensis 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 Mentha canadensis 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: Mentha canadensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Botanical taxa named by Carl Linnaeus, Flora of Asia, Flora of Northern America, so understanding it makes those chapters shorter.
In everyday life: Look for Mentha canadensis 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.
