Phaseolus angustissimus

Phaseolus angustissimus 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 Phaseolus angustissimus rather than just read about it. In short: Phaseolus angustissimus (common name slimleaf bean) is a perennial, herbaceous vine of the Fabaceae (legume) family, native to the American Southwest (particularly, Arizona, New Mexico, and Texas), as well as northern Sonora, Mexico. It is a close relative of the cultivated tepary bean (P. acutifolius), also native to the same region.

Key takeaways

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

Reference excerpt

Phaseolus angustissimus (common name slimleaf bean) is a perennial, herbaceous vine of the Fabaceae (legume) family, native to the American Southwest (particularly, Arizona, New Mexico, and Texas), as well as northern Sonora, Mexico. It is a close relative of the cultivated tepary bean (P. acutifolius), also native to the same region.

Description Phaseolus angustissimus is a perennial, herbaceous vine (to 2 meters) which trails along rocky, eroded hillsides. Its leaflets are distinctively narrow and waxy, it has a very deep, slightly thickened taproot, its flowers are magenta to purple and face upwards from the ground, and its pods are small and curved, yielding 2-4 seeds with a ridged seed coat and hypogeal germination. P. angustissimus has shown freezing resistance in field trials in Canada.

Uses The Zuni people rub the crushed leaves, blossoms and powdered root on a child's body as a strengthener.

Worked examples

Example 1 — a first encounter with Phaseolus angustissimus

Start with the simplest possible case. Write down what Phaseolus angustissimus 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 Phaseolus angustissimus 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 Phaseolus angustissimus 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 Phaseolus angustissimus

In research: Phaseolus angustissimus 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 Phaseolus angustissimus 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: Phaseolus angustissimus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of Northern America, Medicinal plant stubs, Phaseoleae stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Phaseolus angustissimus 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.
