Background
See also: Banksia ser. DryandraThe 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.

Famous quotes containing the word background:
“In the true sense one’s native land, with its background of tradition, early impressions, reminiscences and other things dear to one, is not enough to make sensitive human beings feel at home.”
—Emma Goldman (1869–1940)
“They were more than hostile. In the first place, I was a south Georgian and I was looked upon as a fiscal conservative, and the Atlanta newspapers quite erroneously, because they didn’t know anything about me or my background here in Plains, decided that I was also a racial conservative.”
—Jimmy Carter (James Earl Carter, Jr.)
“I had many problems in my conduct of the office being contrasted with President Kennedy’s conduct in the office, with my manner of dealing with things and his manner, with my accent and his accent, with my background and his background. He was a great public hero, and anything I did that someone didn’t approve of, they would always feel that President Kennedy wouldn’t have done that.”
—Lyndon Baines Johnson (1908–1973)
