Which genus between Borago and Banksia has the greatest number of species within the genus?
Banksia Banksia is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes and fruiting "cones" and heads. Banksias range in size from prostrate woody shrubs to trees up to 30 metres tall. They are found in a wide variety of landscapes; sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts.
Brown's taxonomic arrangement of Banksia Robert Brown's taxonomic arrangement of "Banksia" was published in his book of 1810, "Prodromus Florae Novae Hollandiae et Insulae Van Diemen", and expanded in the supplement to that publication, "Supplementum Primum Prodromi Florae Novae Hollandiae", in 1830. It was the first survey of "Banksia" species to be published, and included descriptions of a number of previously undescribed species.
