Viguiera Explained

Viguiera is a genus of flowering plants in the family Asteraceae. It contains around 19–40 species, which are commonly known as goldeneyes and are native to the New World.^[1] These are herbs to bushy shrubs that bear yellow or orange daisy-like flowers.

Taxonomy

The name honours French physician L. G. Alexandre Viguier (1790–1867).^[2]

It was first described and published by Carl Sigismund Kunth in (F. W. H. von Humboldt, A. J. A. Bonpland and Carl Sigismund Kunth, edited), Nov. Gen. Sp., ed. fol., vol. 4 on page 176 in 1818.^[3]

Recent molecular phylogenetic studies by botanists Schilling and Panero in 2011, showed that these species are within a large group that were formerly classified in the genus Viguiera, and so Aldama has been expanded to include a total of 118 species (most of those from Viguiera).^[4]
