Buckinghamia
''Buckinghamia'' is a genus of only two known species of trees, belonging to the plant family Proteaceae. They are endemic to the rainforests of the wet tropics region of north eastern Queensland, Australia. The ivory curl flower, ''B. celsissima'', is the well known, popular and widely cultivated species in gardens and parks, in eastern and southern mainland Australia, and additionally as street trees north from about Brisbane. The second species, ''B. ferruginiflora'', was only recently described in 1988. History, classification and evolution The genus was named in 1868 by Ferdinand von Mueller in honour of Richard Grenville, the Duke of Buckingham, who was Secretary of State for the Colonies from 1866 to 1868. It was initially placed in a tribe Grevilleae, but the feature of having four ovules per carpel led C. Venkata Rao to classify it in the tribe Telopeae, and within this a new subtribe Hollandaeae based on the antero-posterior orientation of the perianth, with the g ...

Buckinghamia Celsissima
''Buckinghamia celsissima'', commonly known as the ivory curl tree, ivory curl flower or spotted silky oak, is a species of tree in the family Proteaceae. It is endemic to the tropical rainforests of northeastern Queensland, Australia. Description ''Buckinghamia celsissima'' is a large tree growing up to tall in its natural rainforest habitat, but is much smaller when cultivated. The leaves are dark green above and somewhat glaucous or whitish below, held on petioles about long. While the first few leaves on a new shoot may be deeply lobed, those on older twigs are simple with entire margins (see gallery). These mature leaves are elliptic and grow to lengths of around and wide. The showy cream-coloured flowers appear over summer and autumn. The inflorescence is an axillary or terminal pendant raceme up to in length. Individual flowers are densely clustered on the axis, on pedicels about long and have tepals around long. Fruits of the ivory curl tree are follicl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buckinghamia Ferruginiflora
''Buckinghamia ferruginiflora'', also known as Noah's oak or spotted oak, is a species of rainforest tree in the Proteaceae, protea family, one of two in the genus that is endemism, endemic to the Wet Tropics of Queensland, north-eastern Australia. Although the tree's differences from its Congener (biology), congener had been known since the 1970s, it was only species description, formally described by Donald Foreman and Bernard Hyland in 1988 in the journal ''Muelleria (journal), Muelleria''. Description The species grows naturally up to about in height. It has branchlets which are often hairy; leaves long, wide; buds, shoots and flower structures with dense ferruginous (rusty coloured) hairs. The flowers form compound inflorescences long; individual flowers are creamy brown, with dense rusty hairs on the tepals' outer surfaces; the Style (flower), styles are shorter () than those of ''B. celsissima'' (). The fruit Follicle (fruit), follicles are long; the seeds flat with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grevilleoideae
The Grevilleoideae are a subfamily of the plant family Proteaceae. Mainly restricted to the Southern Hemisphere, it contains around 46 genera and about 950 species. Genera include ''Banksia'', ''Grevillea'', and '' Macadamia''. Description The Grevilleoideae grow as trees, shrubs, or subshrubs. They are highly variable, making a simple, diagnostic identification key for the subfamily essentially impossible to provide. One common and fairly diagnostic characteristic is the occurrence of flowers in pairs that share a common bract. However, a few Grevilleoideae taxa do not have this property, having solitary flowers or inflorescences of unpaired flowers. In most taxa, the flowers occur in densely packed heads or spikes, and the fruit is a follicle. Distribution and habitat Grevilleoideae are mainly a Southern Hemisphere family. The main centre of diversity is Australia, with around 700 of 950 species occurring there, and South America also contains taxa. However, the Grevilleoid ...

Opisthiolepis
''Opisthiolepis'' is a genus of a sole described species of large trees, constituting part of the plant family Proteaceae. The species ''Opisthiolepis heterophylla'' most commonly has the names of blush silky oak, pink silky oak, brown silky oak and drunk rabbit. These large trees, up to tall, are endemic to the rainforests of the wet tropics region of north eastern Queensland, Australia. While restricted to this region, within their range they occur widely in rainforests, more common in the tablelands and mountains and described as common on the Atherton Tableland. Taxonomy and naming Queensland botanist Lindsay Smith named the species in 1952, from a collection from the Atherton area in the Cook District. Material had been collected earlier by C.T. White in 1918, but lacked flowers or fruit. They are reported to share their evolutionary closest correlates with the genera ''Buckinghamia'', '' Finschia'', ''Grevillea'' and ''Hakea'' in the subtribe Hakeinae. The genetics ...

Proteaceae
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include '' Protea'', '' Banksia'', '' Embothrium'', '' Grevillea'', '' Hakea'' and '' Macadamia''. Species such as the New South Wales waratah (''Telopea speciosissima''), king protea ('' Protea cynaroides''), and various species of ''Banksia'', ''soman'', and ''Leucadendron'' are popular cut flowers. The nuts of '' Macadamia integrifolia'' are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale. Australia and South Africa have the greatest concentrations of diversity. Etymology The name Proteaceae was adapted by Robert Brown from the name Proteae coined in 1789 for the family by Antoine Laurent de Jussieu, based on the genus ''Protea'', which in 1767 Carl Linnaeus de ...

Royal Botanic Gardens, Melbourne
Royal Botanic Gardens Victoria are botanic gardens across two sites–Melbourne and Cranbourne. Melbourne Gardens was founded in 1846 when land was reserved on the south side of the Yarra River for a new botanic garden. It extends across that slope to the river with trees, garden beds, lakes and lawns. It displays almost 50,000 individual plants representing 8,500 different species. These are displayed in 30 living plant collections. Cranbourne Gardens was established in 1970 when land was acquired by the Gardens on Melbourne's south-eastern urban fringe for the purpose of establishing a garden dedicated to Australian plants. A generally wild site that is significant for biodiversity conservation, it opened to the public in 1989. On the site, visitors can explore native bushland, heathlands, wetlands and woodlands. One of the features of Cranbourne is the Australian Garden, which celebrates Australian landscapes and flora through the display of approximately 170,000 plan ...

Chromosome
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated ( S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Guilfoyle
William Robert Guilfoyle (8 December 1840 – 25 June 1912) was an English landscape gardener and botanist in Victoria, Australia, acknowledged as the architect of the Royal Botanic Gardens, Melbourne and was responsible for the design of many parks and gardens in Melbourne and regional Victoria. Early life and family Guilfoyle was born in Chelsea, England, to Charlotte (née Delafosse) and Michael Guilfoyle (1809–1884), a landscape gardener and nurseryman. William was one of four children. The family migrated to Sydney in 1849 on board the ''Steadfast''. Later after arriving, Michael Guilfoyle established ''Guilfoyle's Exotic Nursery'' in Double Bay on land owned by Thomas Sutcliffe Mort. Here he was a leading supplier of the exotic Jacaranda tree using his own grafting methods. William Guilfoyle was privately educated at Lyndhurst College, Glebe where he received botanical instruction by William Woolls, William Sharp MacLeay (1792–1865) and John MacGillivray (1821–1867 ...
