Ladeania lanceolata

Ladeania lanceolata 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 Ladeania lanceolata rather than just read about it. In short: Ladeania lanceolata (syn. Psoralidium lanceolatum) is a species of flowering plant in the legume family known by several common names, including lemon scurfpea, wild lemonweed, and dune scurfpea.

Key takeaways

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

Reference excerpt

Ladeania lanceolata (syn. Psoralidium lanceolatum) is a species of flowering plant in the legume family known by several common names, including lemon scurfpea, wild lemonweed, and dune scurfpea.

It is native to western North America from central Canada to California to Texas, where it grows in sandy habitat, such as alluvial plains and sagebrush.

Description It is a perennial herb with a branching, heavily glandular stem growing 30 to 60 centimeters tall. The leaves are palmately compound, each made up of usually three linear or lance-shaped leaflets borne on a short petiole. The inflorescence is a raceme of flowers emerging from a leaf axil. Each flower is under a centimeter long with a pealike corolla in shades of light purple-blue to white. The fruit is a hairy, glandular, spherical legume.

Taxonomy Ladeania lanceolata was given its first scientific description by the botanist Frederick Traugott Pursh in 1813. He named it Psoralea lanceolata. It was moved to the genus Psoralidium by Per Axel Rydberg in 1919 with the name Psoralidium lanceolatum. He also separated out six variants as species that are now regarded as synonyms. In 2009 James Lauritz Reveal and Ashley Noel Egan published a paper where they reclassified with the name Ladeania lanceolata. Ladeania lanceolata is listed as the accepted name by Plants of the World Online, World Flora Online, and World Plants. It continues to be listed as Psoralidium lanceolatum by the USDA Natural Resources Conservation Service PLANTS database.

Traditional uses The Zuni people eat the fresh flowers to treat stomachaches.

Worked examples

Example 1 — a first encounter with Ladeania lanceolata

Start with the simplest possible case. Write down what Ladeania lanceolata 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 Ladeania lanceolata 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 Ladeania lanceolata 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 Ladeania lanceolata

In research: Ladeania lanceolata 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 Ladeania lanceolata 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: Ladeania lanceolata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Faboideae stubs, Medicinal plant stubs, NatureServe secure species, so understanding it makes those chapters shorter.
In everyday life: Look for Ladeania lanceolata 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.
