Reference excerpt

Gwendoline Joyce Lewis (1909–1967) was a South African botanist.

Life She graduated from the University of Cape Town, with a PhD. She was active in the description and classification of species of the family of the Iridaceae. She was an accomplished plant collector and added over 8000 plant specimens to herbaria. She was botanist at the Bolus Herbarium of the University of Cape Town for 2 years and then was appointed curator of the South African Museum Herbarium. In 1956 this herbarium and its staff moved to Kirstenbosch National Botanical Garden. Lewis was appointed a Research Officer with the National Botanical Gardens. She was a Fellow of the Royal Society of South Africa. She died in Cape Town on 11 April 1967. The following plants were named after her: Geissorhiza lewisiae Forester; Muraltia lewisiae Levyns; Psilocaulon lewisiae Lbol and Thamnochortus lewisiae Pillans.

Works The standard author abbreviation G.J.Lewis is used to indicate this person as the author when citing a botanical name.

Worked examples

Example 1 — a first encounter with Gwendoline Joyce Lewis

Start with the simplest possible case. Write down what Gwendoline Joyce Lewis 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 Gwendoline Joyce Lewis 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 Gwendoline Joyce Lewis 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 Gwendoline Joyce Lewis

In research: Gwendoline Joyce Lewis 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 Gwendoline Joyce Lewis 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: Gwendoline Joyce Lewis is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1909 births, 1967 deaths, 20th-century South African botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Gwendoline Joyce Lewis 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.
