Bentham's taxonomic arrangement of Dryandra
George Bentham's taxonomic arrangement of ''Dryandra'' (now ''B.'' ser. ''Dryandra'') was published in 1870, in Volume 5 of Bentham's ''Flora Australiensis''. It replaced the 1856 arrangement of Carl Meissner, and stood for over a century before being replaced by the 1996 arrangement of Alex George.
==Background==
The dryandras are a group of proteaceous shrubs endemic to southwest Western Australia. For nearly two hundred years they were considered a separate genus, having been published at that rank in 1810 by Robert Brown. In 2007 it was transferred into the genus ''Banksia'' as ''B.'' ser. ''Dryandra''. There are now just under 100 species, plus numerous subspecies and varieties.
The first infrageneric arrangement of ''Dryandra'' was Brown's 1810 arrangement, which listed 13 species, but did not attempt an infrageneric classification. Twenty years later, Brown published a revised arrangement which divided 23 recognised species in three subgenera, and placed one further species in a separate genus ''Hemiclidia''. This was followed by the 1856 arrangement of Carl Meissner, which recognised 53 species and six varieties, dividing them into three sections and eight series, and maintaining the monospecific genus ''Hemiclidia''.
