Taxonomy of Adenanthos

Taxonomy of Adenanthos 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 Taxonomy of Adenanthos rather than just read about it. In short: George Bentham's taxonomic arrangement of Adenanthos was the first comprehensive taxonomic arrangement of that plant genus. It was published in 1870 in his landmark flora of Australia, Flora Australiensis.

Key takeaways

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

Reference excerpt

George Bentham's taxonomic arrangement of Adenanthos was the first comprehensive taxonomic arrangement of that plant genus. It was published in 1870 in his landmark flora of Australia, Flora Australiensis. It would stand for over a hundred years before being superseded by the 1978 arrangement of Ernest Charles Nelson.

Background

Adenanthos is a genus of around 30 species in the plant family Proteaceae. Endemic to southern Australia, they are evergreen woody shrubs with solitary flowers that are pollinated by birds and, if fertilised, develop into achenes. They are not much cultivated. Common names of species often include one of the terms woollybush, jugflower and stick-in-the-jug. The first known botanical collection of Adenanthos was made by Archibald Menzies during the September 1791 visit of the Vancouver Expedition to King George Sound on the south coast of Western Australia. However this did not lead to publication of the genus. Jacques Labillardière collected specimens of A. cuneatus from Esperance Bay the following year, and in 1803 Jean Baptiste Leschenault de la Tour collected the same two species as Menzies had 12 years earlier. Labillardière published the genus in 1805, in his Novae Hollandiae Plantarum Specimen, based on the specimens collected by himself and Leschenault. The genus was given the name Adenanthos from the Greek αδην (aden-, "gland") and ανθοσz (-anthos, "flower"), in reference to the prominent nectaries. By 1870, 13 species had been published. That year, Bentham published the fifth volume of his Flora Australiensis, in which was contained a treatment of the plant family Proteaceae, including Adenanthos.

Bentham's arrangement In his treatment of Adenanthos, Bentham published a fourteenth species, and the first infrageneric arrangement: he divided the genus into two taxonomic sections, A. sect. Eurylaema and A. sect. Stenolaema, based on the shape of the perianth tube: members of A. sect. Eurylaema have perianth tubes that are curved and swollen above the middle, whereas members of A. sect. Stenolaena have perianth tubes that are straight and unswollen. The full arrangement is as follows:

Adenanthos A. sect. Eurylaema A. barbigera (now A. barbiger) A. obovata (now A. obovatus) A. sect. Stenolaena (now A. sect. Adenanthos) A. cuneata (now A. cuneatus) A. Cunninghamii (now A. × cunninghamii) A. pungens A. venosa (now A. venosus) A. Dobsoni (now A. dobsonii) A. linearis A. sericea (now A. sericeus) A. Meissneri (now A. meisneri) A. filifolia (now A. filifolius) A. terminalis A. flavidiflora (now A. flavidiflorus) A. apiculata (now A. apiculatus)

Legacy Bentham's arrangement stood for over a hundred years, by which time a number of new species had been discovered, rendering Bentham's treatment "very inadequate and incomplete". His division of the genus into two sections based on perianth shape is still accepted today, but changes in the laws of botanical nomenclature mean that A. sect. Stenolaema is now known as A. sect. Adenanthos, and all specific epithets now have masculine gender; for example, the species that Bentham referred to as Adenanthos barbigera is now named Adenanthos barbiger.

Worked examples

Example 1 — a first encounter with Taxonomy of Adenanthos

Start with the simplest possible case. Write down what Taxonomy of Adenanthos 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 Taxonomy of Adenanthos 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 Taxonomy of Adenanthos 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 Taxonomy of Adenanthos

In research: Taxonomy of Adenanthos 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 Taxonomy of Adenanthos 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: Taxonomy of Adenanthos is common in secondary-school and first-year university syllabi. It links to neighbouring topics Adenanthos, George Bentham, Plant taxonomies, so understanding it makes those chapters shorter.
In everyday life: Look for Taxonomy of Adenanthos 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.
