Lycium andersonii

Lycium andersonii is a science 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 Lycium andersonii rather than just read about it. In short: Lycium andersonii is a species of flowering plant in the nightshade family, Solanaceae. Its common names include water-jacket, redberry desert-thorn, Anderson thornbush, Anderson's desert thorn, Anderson boxthorn, Anderson lycium, Anderson wolfberry, and squawberry.

Key takeaways

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

Reference excerpt

Lycium andersonii is a species of flowering plant in the nightshade family, Solanaceae. Its common names include water-jacket, redberry desert-thorn, Anderson thornbush, Anderson's desert thorn, Anderson boxthorn, Anderson lycium, Anderson wolfberry, and squawberry. The species is native to the Southwestern United States and northwestern Mexico, where it is distributed in New Mexico, Arizona, California, Nevada, Utah, Baja California, Sinaloa, and Sonora. It grows in many habitat types and plant communities, including pinyon-juniper woodland, creosote bush scrub, sagebrush scrub, chaparral, and coastal sage scrub. This plant is a shrub growing up to about 2.7 metres (8 ft 10 in) in maximum height. It grows from a large fibrous root system which can extend over 9 metres (30 ft) from the base of the plant. The shrub is rounded in shape with many branches covered in many thin spines up to 2 centimetres (0.79 in) long. The flat leaves are thick and fleshy, measuring up to 1.7 centimetres (0.67 in) long. They are shed from the plant in dry conditions. The flowers have funnel-shaped white or purple-tinged corollas up to a centimeter long. The fruit is a red or orange berry less than a centimeter long. This plant grows in sandy, gravelly washes and on slopes and mesas. It tolerates some soil salinity and alkaline soils such as caliche. It thrives in hot, dry climates. It is rarely dominant in the local flora. Common associates include creosote bush (Larrea tridentata), yellow palo verde (Parkinsonia microphylla), white bursage, (Ambrosia dumosa), smoke tree (Psorothamnus spinosus), Nevada ephedra (Ephedra nevadensis), hop sage (Grayia spinosa), pale wolfberry (Lycium pallidum), blackbrush (Coleogyne ramosissima), singlewhorl burrobrush (Hymenoclea monogyra), and Joshua tree (Yucca brevifolia). It was named after Charles Lewis Anderson by Asa Gray.

Worked examples

Example 1 — a first encounter with Lycium andersonii

Start with the simplest possible case. Write down what Lycium andersonii claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Lycium andersonii 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 Lycium andersonii 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 Lycium andersonii

In research: Lycium andersonii appears in science 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 Lycium andersonii 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: Lycium andersonii is common in secondary-school and first-year university syllabi. It links to neighbouring topics Flora of Arizona, Flora of Baja California, Flora of California, so understanding it makes those chapters shorter.
In everyday life: Look for Lycium andersonii 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.
