Brown's Taxonomic Arrangement Of Dryandra
Robert Brown's taxonomic arrangement of ''Dryandra'' was the first arrangement of what is now ''Banksia'' ser. ''Dryandra''. His initial arrangement was published in 1810, and a further arrangement, including an infrageneric classification, followed in 1830. Aspects of Brown's arrangements can be recognised in the later arrangements of George Bentham and 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 they were transferred into the genus '' Banksia'' as ''B.'' ser. ''Dryandra''. There are now nearly 100 species, plus numerous subspecies and varieties. Brown's 1810 arrangement The genus ''Dryandra'' was first published by Brown in "On the natural order of plants called Proteaceae", which was read to the Linnean Society of London in 1809, and published the following year in Vo ...

Robert Brown (botanist, Born 1773)
Robert Brown (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms and angiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, notably erecting a number of plant families that are still accepted today; and numerous Australian plant genera and species, the fruit of his exploration of that continent with Matthew Flinders. Early life Robert Brown was born in Montrose on 21 December 1773, in a house that existed on the site where Montrose Library currently stands. He was the son of James Brown, a minister in the ...

Dryandra Sect
''Banksia'' ser. ''Dryandra'' is a series of 94 species of shrub to small tree in the plant genus ''Banksia''. It was considered a separate genus named ''Dryandra'' until early 2007, when it was merged into ''Banksia'' on the basis of extensive molecular and morphological evidence that ''Banksia'' was paraphyletic with respect to ''Dryandra''. Taxonomy The dryandras were named in honour of Swedish botanist Jonas C. Dryander. The first specimens of a ''Dryandra'' were collected by Archibald Menzies, surgeon and naturalist to the Vancouver Expedition. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of '' B. sessilis'' (Parrotbush) and '' B. pellaeifolia''. Upon Menzies' return to England, he turned his specimens over to Banks; as with most other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryandra Verae
''Dryandra'' subg. ''Dryandra'' is an obsolete clade of plant. It was a series within the former genus ''Dryandra'' (now ''Banksia'' ser. ''Dryandra''). The name was first published at sectional rank as ''Dryandra verae'' in 1830, before being renamed ''Eudryandra'' in 1847, the replaced by the autonym at subgenus rank in 1996. It was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk ''Dryandra'' into '' Banksia''. Brown's ''Dryandra verae'' ''Dryandra verae'' ("True Dryandra") was published by Brown in his 1830 ''Supplementum primum Prodromi florae Novae Hollandiae''. Brown's arrangement of ''Dryandra'' split a single species out into a separate genus, and divided the remaining ''Dryandra'' species into three groups according to what Brown perceived to be variations in the number of seed separators. He allowed for these groups to be treated at subgenus or section rank, but they are now treated as having been published as sections. ''Dryandra verae'' was ...

Follicle (fruit)
In botany, a follicle is a dry unilocular fruit formed from one carpel, containing two or more seeds. It is usually defined as dehiscing by a suture in order to release seeds, for example in ''Consolida'' (some of the larkspurs), peony and milkweed (''Asclepias''). Some difficult cases exist however, so that the term indehiscent follicle is sometimes used, for example with the genus ''Filipendula'', which has indehiscent fruits that could be considered intermediate between a (dehiscent) follicle and an (indehiscent) achene. An aggregate fruit that consists of follicles may be called a follicetum. Examples include hellebore, aconite, ''Delphinium'', ''Aquilegia'' or the family Crassulaceae, where several follicles occur in a whorl on a shortened receptacle, or ''Magnolia'', which has many follicles arranged in a spiral on an elongated receptacle. The follicles of some species dehisce by the ventral suture (as in ''Banksia''), or by the dorsal suture (as in ''Magnolia'').Kapil, R. ...
