Lannea microcarpa

Lannea microcarpa 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 Lannea microcarpa rather than just read about it. In short: Lannea microcarpa is a dioecious plant within the Anacardiaceae family. It is also called African grapes and occurs in the Sudan and Guinea savanna of West Africa from Senegal to Cameroon.

Key takeaways

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

Reference excerpt

Lannea microcarpa is a dioecious plant within the Anacardiaceae family. It is also called African grapes and occurs in the Sudan and Guinea savanna of West Africa from Senegal to Cameroon. The plant is used to dye basilan fini, a traditional cloth in a red and brown colour.

Description The species is capable of growing up to 15 m high with a rather short trunk and dense crown, it has a grey and smooth bark with a reddish and white fibrous slash. Leaves; alternate and imparipinnate, up to 23 cm long, with 2–3 leaflets per pinnae; leaf-blade is narrowly ovate in outline, 5–13 cm long and 2.5–6 cm wide, leaflets have a rough and waxy adaxial surface. Inflorescence is terminal raceme. Fruits are ellipsoid in shape, grows in raceme like bundles of between 3-25, purple to blackish color when ripe.

Distribution Occurs in the Sudanian and Guinea savannas of West Africa and in Cameroon.

Chemistry Chemical compounds isolated from the leaves of Lannea microcarpa include polyphenols and novel flavanoids such as 4'-methoxy-myricetin 3-O-α-L-rhamnopyranoside, myricetin 3-O-α-L-rhamnopyranoside, and myricetin 3-O-β-D-glucopyranoside, vitexin, isovitexin, and gallic acid.

Uses

Leaf extracts of the species is traditionally used in would healing process and for topical treatments of various ailments including conjunctivitis, gingivitis and stomatitis. A root bark decoction is applied to treat stomach and skin related troubles. Its leaves and fruits are collected and eaten by locals. The exudate from the bark is applied in the dyeing process of hand-made cloths, red-brown dye is applied to basil-lan fini, a traditional medicine cloth and other locally handmade fabrics.

Worked examples

Example 1 — a first encounter with Lannea microcarpa

Start with the simplest possible case. Write down what Lannea microcarpa 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 Lannea microcarpa 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 Lannea microcarpa 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 Lannea microcarpa

In research: Lannea microcarpa 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 Lannea microcarpa 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: Lannea microcarpa is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of West Tropical Africa, Fruit stubs, Fruit tree stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Lannea microcarpa 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.
