Reference excerpt

Larix gmelinii var. olgensis, synonym Larix olgensis, the Olga Bay larch or Olgan larch, is a variety of larch. The variety is named after Olga Bay in the Sea of Japan. The common name in Japanese language is 満洲唐松 (Manshu'u Kara-matsu). The common name in Chinese is 黄花落叶松 (pinyin: huang hua luo ye song). This variety occurs in Central Sikhote-Alin, and rarely occurs in North Korea, and Jilin and eastern Heilongjiang provinces of China, between 500 and 1100 metres in elevation. This deciduous coniferous tree grows to 25–30 meters tall with a trunk reaching a meter in diameter at breast high, with gray to gray-brown bark with flaking and scaly fissured bark. Its leaves are needle-like, dark-green, 1.5–3 cm long and 1 cm wide. The reddish purple or violet cones mature to light brown, sometimes tinged with purple, and range from 18 to 25 mm long. Pollination occurs in May with seeds maturing in September-October. It grows in mountains and on moist slopes and in swamps. The timber has many uses in construction and for wood fiber. The trunk is used to produce resin while the bark is used for tannins.

Worked examples

Example 1 — a first encounter with Larix gmelinii var. olgensis

Start with the simplest possible case. Write down what Larix gmelinii var. olgensis 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 Larix gmelinii var. olgensis 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 Larix gmelinii var. olgensis 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 Larix gmelinii var. olgensis

In research: Larix gmelinii var. olgensis 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 Larix gmelinii var. olgensis 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: Larix gmelinii var. olgensis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Deciduous conifers, Flora of Northeast Asia, IUCN Red List near threatened species, so understanding it makes those chapters shorter.
In everyday life: Look for Larix gmelinii var. olgensis 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.
