Etymology

The genus ''Protea'' was named in 1735 by

Carl Linnaeus Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the ...

, who could change his form at will, possibly because they have such a wide variety of forms. Linnaeus's genus was formed by merging a number of genera previously published by

Herman Boerhaave Herman Boerhaave (, 31 December 1668 – 23 September 1738Underwood, E. Ashworth. "Boerhaave After Three Hundred Years." ''The British Medical Journal'' 4, no. 5634 (1968): 820–25. https://www.jstor.org/stable/20395297.) was a Dutch botanist, ...

, although precisely which of Boerhaave's genera were included in Linnaeus's ''Protea'' varied with each of Linnaeus's publications.

Taxonomy

The family Proteaceae to which ''Protea'' species belong is an ancient one among

Botanical history

Proteas attracted the attention of botanists visiting the

in the 17th century. Many species were introduced to Europe in the 18th century, enjoying a unique popularity at the time amongst botanists.

Cultivation

Proteas are currently cultivated in over 20 countries. Cultivation is restricted to Mediterranean and subtropical climates. Three categories of traits have to be considered before developing a new cultivar. The yield or production capacity of the cultivar must be considered. The ease of handling and packaging of the cut stems and the last category is to consider the perceived market value of the cultivar The cultivation of a ''Protea ''plant is time-consuming, so good planning when developing the cross combinations and goals are of great importance of the breeding programme. Some protea flower species, like the

, thus rely on cross-pollination for successive seed set. The main vectors responsible for the transfer of pollen in protea cultivation are birds, insects, and wind. Some ''Protea'' species exhibit both self-pollination and cross-pollination as a method of reproduction. Cross-pollination is preferred, though, as a method of reproduction because it provides genetic diversity in the population. When cultivating proteas, breeders use hand pollination as a controlled method to transfer pollen from one flower to another. Proteas usually flower during spring. The general structure of their flower heads consists of a mass of flowers on a woody receptacle. The ovary is protected by the receptacle, thus is not seen when looking at the flower, but the anthers are present at the top of the flower, which can then easily transfer the pollen to the vectors. The common Proteaceae plants, e.g. ''Protea'', ''
