Grevillea Juniperina
''Grevillea juniperina'', commonly known as juniper- or juniper-leaf grevillea or prickly spider-flower, is a plant of the family Proteaceae native to eastern New South Wales and southeastern Queensland in Australia. Scottish botanist Robert Brown described the species in 1810, and seven subspecies are recognised. One subspecies, ''G. j. juniperina'', is restricted to Western Sydney and environs and is threatened by loss of habitat and housing development. A small, prickly-leaved shrub between high, ''G. juniperina'' generally grows on clay-based or alluvial soils in eucalypt woodland. The flower heads, known as inflorescences, appear from winter to early summer and are red, orange or yellow. Birds visit and pollinate the flowers. ''Grevillea juniperina'' plants are killed by bushfire, regenerating afterwards from seed. ''Grevillea juniperina'' adapts readily to cultivation and has been important in horticulture as it is the parent of many popular garden hybrids. Descrip ...

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 ...

Axillary Bud
The axillary bud (or lateral bud) is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots (flowers). Once formed, a bud may remain dormant for some time, or it may form a shoot immediately. Overview An axillary bud is an embryonic or organogenic shoot which lies dormant at the junction of the stem and petiole of a plant. It arises exogenously from outer layer of cortex of the stem. Axillary buds do not become actively growing shoots on plants with strong apical dominance (the tendency to grow just the terminal bud on the main stem). Apical dominance occurs because the shoot apical meristem produces auxin which prevents axillary buds from growing. The axillary buds begin developing when they are exposed to less auxin, for example if the plant naturally has weak apical dominance, if apical dominance is broken by removi ...

Prodromus Florae Novae Hollandiae Et Insulae Van Diemen
''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'' (Prodromus of the Flora of New Holland and Van Diemen's Land) is a flora of Australia written by botanist Robert Brown and published in 1810. Often referred to as ''Prodromus Flora Novae Hollandiae'', or by its standard botanical abbreviation ''Prodr. Fl. Nov. Holland.'', it was the first attempt at a survey of the Australian flora. It described over 2040 species, over half of which were published for the first time. Brown's ''Prodromus'' was originally published as Volume One, and following the ''Praemonenda'' (Preface), page numbering commences on page 145. Sales of the ''Prodromus'' were so poor, however, that Brown withdrew it from sale. Due to the commercial failure of the first volume, pages 1 to 144 were never issued, and Brown never produced the additional volumes that he had planned. In 1813, a book of illustrations for the ''Prodromus'' was published separately by Ferdinand Bauer under the title ''Ferdinandi Ba ...

Prospect, New South Wales
Prospect is a suburb of Sydney, in the state of New South Wales, Australia. Prospect is located 32 kilometres west of the Sydney central business district in the local government area of the City of Blacktown and is part of the Greater Western Sydney region. One of the oldest suburbs in Sydney, Prospect takes its name from the prominent nearby landmark of Prospect Hill - from the top of which people could ''get a prospect of'' (see a great distance) the surrounding countryside. Initially a settlement for emancipated convicts, it later became a village. Since colonisation, settlers cleared larger areas of land to raise livestock, build churches, inns, schools, shops and a large reservoir. Naturalist Charles Darwin visited Prospect in January 1836, to observe the geology. History Prior to the arrival of the First Fleet in 1788, Prospect was inhabited by different groups of the Darug people including the Warmuli. The Aboriginals there were of the woods culture. As European settl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Caley
George Caley (10 June 1770 – 23 May 1829) was an English botanist and explorer, active in Australia for the majority of his career. Early life Caley was born in Craven, Yorkshire, England, the son of a horse-dealer. He was educated at the Free Grammar School at Manchester for around four years and was then taken into his father's stables. According to a letter which was sent to William Withering on 15 June 1798, he started teaching himself botany after he coming across a volume of book about farriery which was written by William Gibson cause he became interested in the herbs mentioned in prescriptions. He started learning botany by studying Botanical arrangement (1787-92) by William Withering. He changed his job to that of a weaver in order to allow himself to spent more time with his associate in Manchester School of Botanists which consist of John Mellor, James Crowther, and John Dewhurst. This school was also attended by John Horsefield on 1808. In March 1795 he wrote t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donald McGillivray (botanist)
Donald John McGillivray (20 August 1935 – 17 August 2012) in New South Wales, Australia, usually known as D.J. McGillivray, was an Australian botanical taxonomist. He was trained in forestry, and became interested in plant taxonomy just before he transferred in 1964 to the National Herbarium of the Royal Botanic Gardens in Sydney, New South Wales. From 1969 to 1970, he was the Australian Botanical Liaison Officer at the Royal Botanic Gardens in Kew, London. McGillivray specialised in the ''Grevillea'' genus Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus com ..., and in 1993 published ''Grevillea – Proteaceae: A Taxonomic Revision'', a definitive scientific survey of the prolific Australian plant genus.

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Juniper
Junipers are coniferous trees and shrubs in the genus ''Juniperus'' () of the cypress family Cupressaceae. Depending on the taxonomy, between 50 and 67 species of junipers are widely distributed throughout the Northern Hemisphere, from the Arctic, south to tropical Africa, throughout parts of West Asia, western, Central Asia, central and South Asia, southern Asia, east to eastern Tibet in the Old World, and in the mountains of Central America. The highest-known juniper forest occurs at an altitude of in southeastern Tibet and the northern Himalayas, creating one of the highest tree lines on earth. Description Junipers vary in size and shape from tall trees, tall, to columnar or low-spreading shrubs with long, trailing branches. They are evergreen with needle-like and/or scale-like leaves. They can be either monoecious or dioecious. The female Conifer cone, seed cones are very distinctive, with fleshy, fruit-like coalescing scales which fuse together to form Juniper berry, a&n ...

Port Jackson
Port Jackson, consisting of the waters of Sydney Harbour, Middle Harbour, North Harbour and the Lane Cove and Parramatta Rivers, is the ria or natural harbour of Sydney, New South Wales, Australia. The harbour is an inlet of the Tasman Sea (part of the South Pacific Ocean). It is the location of the Sydney Opera House and Sydney Harbour Bridge. The location of the first European settlement and colony on the Australian mainland, Port Jackson has continued to play a key role in the history and development of Sydney. Port Jackson, in the early days of the colony, was also used as a shorthand for Sydney and its environs. Thus, many botanists, see, e.g, Robert Brown's ''Prodromus Florae Novae Hollandiae et Insulae Van Diemen'', described their specimens as having been collected at Port Jackson. Many recreational events are based on or around the harbour itself, particularly Sydney New Year's Eve celebrations. The harbour is also the starting point of the Sydney to Hobart Yacht ...
