Brown's taxonomic arrangement of Banksia : ウィキペディア英語版 | 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. ==Background==
''Banksia'' is a genus of around 175 species in the plant family Proteaceae. An iconic Australian wildflower and popular garden plant, they are recognised by their flower spikes or domes, and their fruiting "cones". They grow in forms varying from prostrate woody shrubs to trees up to 35 metres tall, and occur in all but the most arid areas of Australia. As heavy producers of nectar, they are important sources of food for nectariferous animals such as honeyeaters and honey possum, and they are of economic importance to the nursery and cut flower industries. However they are seriously threatened by a number of processes including land clearing, frequent burning, and disease, and a number of species are rare and endangered.
