Reference excerpt

Hymenocallis pimana is a member of the genus Hymenocallis, in the family Amaryllidaceae. Common name in English is Pima spider-lily; in Spanish it is cebollín. It is endemic to a small mountainous region in the Sierra Madre Occidental, straddling the Mexican states of Chihuahua and Sonora. Many of the people of the region are of the indigenous group known as the Mountain Pima or Pima Bajo. Type locale is the small village of Nabogame, approximately 18 km northwest of Yepáchic, Chihuahua and about 10 km east of the frontier with Sonora. This is at elevation of approximately 1800 m (6000 ft).

Ecology The plant is locally abundant in the vicinity of the type locale. It grows in large colonies of hundreds of individuals, often near waterways and gulleys. This largely due to the nature of the large, green seeds which fall on the ground and germinate close to the parent plant without much dispersal. The large, showy flowers appear in June, at the beginning of the summer rainy season. Flowers are white and erect, with narrow perianth segments and a prominent corolla. Bulbs resemble small onion bulbs.

Uses The Pima peoples of the region report that these bulbs provided an emergency food source in years past, during famines that followed crop failures. They say that the bulbs were boiled in lye to remove toxic alkaloids before consumption. This is the only known instance of any people utilizing any member of this genus as food.

Worked examples

Example 1 — a first encounter with Hymenocallis pimana

Start with the simplest possible case. Write down what Hymenocallis pimana 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 Hymenocallis pimana 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 Hymenocallis pimana 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 Hymenocallis pimana

In research: Hymenocallis pimana 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 Hymenocallis pimana 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: Hymenocallis pimana is common in secondary-school and first-year university syllabi. It links to neighbouring topics Amaryllidaceae stubs, Edible plants, Flora of Chihuahua (state), so understanding it makes those chapters shorter.
In everyday life: Look for Hymenocallis pimana 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.
