Dryandra Ser. Ilicinae
''Dryandra'' ser. ''Ilicinae'' is an obsolete series within the former genus ''Dryandra'' (now ''Banksia'' ser. ''Dryandra''). It was first published by Carl Meissner in 1856, but was discarded by George Bentham in 1870. It was reinstated with a new circumscription by Alex George in 1996, but was ultimately discarded again in 2007 when Austin Mast and Kevin Thiele sunk ''Dryandra'' into '' Banksia''. According to Meissner This taxon was first published by Meissner in his 1856 chapter on the Proteaceae in A. P. de Candolle's ''Prodromus systematis naturalis regni vegetabilis''.. Meissner's arrangement followed that of Robert Brown in segregating a single species into the genus ''Hemiclidia'', and dividing the remaining species into three sections according to what were perceived to be variations in the number of seed separators. Meissner then further divided ''D.'' sect. ''Eudryandra'' into eight unranked groups signified by the symbol "§". The first of these, ''Dry ...

Banksia Undata 9
''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. ...

Banksia Heliantha
''Banksia heliantha'', commonly known as oak-leaved dryandra, is a species of shrub that is endemic to Western Australia. It has hairy stems, serrated, egg-shaped to wedge-shaped leaves, golden yellow flowers and partly woolly follicles. Description ''Banksia heliantha'' is a robust, openly-branched shrub that typically grows to a height of and has hairy stems but does not form a lignotuber. The leaves are wedge-shaped to egg-shaped with the narrower end towards the base, long and wide on a petiole up to long. The leaves have between five and fifteen sharply-pointed teeth up to long on each side. The flowers are borne in groups of between 140 and 160 in a head on the ends of branches with hairy, tapering linear involucral bracts up to long at the base of the head. The flowers have a golden yellow perianth is long that is hairy at its base and a yellow pistil long and glabrous. Flowering occurs in March or from July to October and the follicles are egg-shaped, long an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Australiensis
''Flora Australiensis: a description of the plants of the Australian Territory'', more commonly referred to as ''Flora Australiensis'', and also known by its standard abbreviation ''Fl. Austral.'', is a seven-volume flora of Australia published between 1863 and 1878 by George Bentham, with the assistance of Ferdinand von Mueller. It was one of the famous Kew series of colonial floras, and the first flora of any large continental area that had ever been finished. In total the flora included descriptions of 8125 species.Orchard, A. E. 1999. Introduction. In A. E. Orchard, ed. ''Flora of Australia - Volume 1'', 2nd edition pp 1-9. Australian Biological Resources Study Bentham prepared the flora from Kew; with Mueller, the first plant taxonomist residing permanently in Australia, loaning the entire collection of the National Herbarium of Victoria to Bentham over the course of several years. Mueller had been dissuaded from preparing a flora from Australia while in Australia by Bentham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Sessilis
''Banksia sessilis'', commonly known as parrot bush, is a species of shrub or tree in the plant genus ''Banksia'' of the family Proteaceae. It had been known as ''Dryandra sessilis'' until 2007, when the genus '' Dryandra'' was sunk into ''Banksia''. The Noongar peoples know the plant as budjan or butyak. Widespread throughout southwest Western Australia, it is found on sandy soils over laterite or limestone, often as an understorey plant in open forest, woodland or shrubland. Encountered as a shrub or small tree up to in height, it has prickly dark green leaves and dome-shaped cream-yellow flowerheads. Flowering from winter through to late spring, it provides a key source of food—both the nectar and the insects it attracts—for honeyeaters in the cooler months, and species diversity is reduced in areas where there is little or no parrot bush occurring. Several species of honeyeater, some species of native bee, and the European honey bee seek out and consume the nectar, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryandra Ser
''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] |
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 ...
