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 ...

Flora Australiensis V5 Title Page
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phyt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banksia Squarrosa Subsp
''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 (100 ft) 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. Heavy producers of nectar, ''banksias'' are a vital part of the food chain in the Australian bush. They are an important food source for nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare and endangered. ...
