Acacia Gillii
''Acacia gillii'', commonly known as Gill's wattle, is a shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae'' that is native to parts of southern Australia. It is named after Austrian botanist Alexander Gilli. Description The shrub typically grows to a height of and has a straggly open habit. It has pendulous branches with flexuous branchlets that are flat or angled at extremities The glabrous branchlets are a dark red-brown colour. The evergreen, patent and sometimes reflexed phyllodes have a narrowly oblanceolate shape that is sometimes linear to shallowly incurved. The phyllodes have a length of and a width of and are tapered at the base with prominent margins and midrib. The simple inflorescences have spherical flower-heads containing 43 to 72 densely packed golden flowers. The linear brown seed pods that form after flowering have a length of up to and a width of and contain dull black elliptic seeds with a length of . Taxonomy The species was firs ...

Joseph Maiden
Joseph Henry Maiden (25 April 1859 – 16 November 1925) was a botanist who made a major contribution to knowledge of the Australian flora, especially the genus ''Eucalyptus''. This botanist is denoted by the author abbreviation when citing a botanical name. Life Joseph Maiden was born in St John's Wood in northwest London. He studied science at the University of London, but due to ill health he did not complete the course. As part of his treatment he was advised to take a long sea voyage, and so in 1880 he sailed for New South Wales. In 1881, Maiden was appointed first curator of the Technological Museum in Sydney (now the Powerhouse Museum), remaining there until 1896. While there, he published an article in 1886 describing what he called "some sixteenth century maps of Australia". These were the so-called Dieppe maps, the Rotz (1547), the Harleian or Dauphin (mid-1540s), and the Desceliers (1550), photo-lithographic reproductions of which had been published by the Briti ...

Acacia Cretacea
''Acacia cretacea'', also known as chalky wattle, is a shrub belonging to the genus ''Acacia'' and the subgenus ''Phyllodineae'' that is endemic to South Australia. Description The shrub or small tree usually has a single stem and can grow to a height of and has a spindly habit with an open crown. It has smooth grey or reddish-brown bark found on the on lower trunk. The grey to medium green coloured phyllodes have a narrowly elliptic to narrowly oblanceolate shape with a length of up to around and a width of . It blooms intermittently between July and January producing inflorescences containing 5 to 14 spherical coloured flower-heads. The flower-heads have a diameter of and contain 35 to 45 densely packed lemon yellow to golden yellow coloured flowers. The straight to slightly curved pale brown coloured seed pods that form after flowering have a length of up to and a width of and contain black, oblong to ovoid shaped seeds with a length of around and a width of .

Plants Described In 1927
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Flora Of South Australia
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Acacia Species
Several Cladistics, cladistic analyses have shown that the genus ''Acacia sensu lato, Acacia'' is not monophyletic. While the subg. ''Acacia'' and subg. ''Phyllodinae'' are monophyletic, subg. ''Aculeiferum'' is not. This subgenus consists of three clades. Therefore, the following list of ''Acacia'' species cannot be maintained as a single entity, and must either be split up, or broadened to include species previously not in the genus. This genus has been provisionally divided into 5 genus, genera, ''Acacia'', ''Vachellia'', ''Senegalia'', ''Acaciella'' and ''Mariosousa''. The proposed type species of ''Acacia'' is ''Acacia penninervis''. Which of these segregate genera is to retain the name ''Acacia'' has been controversial. The genus was previously typified with the African species ''Acacia scorpioides'' (L.) W.F.Wright, a synonym of ''Acacia nilotica'' (L.) Delile. Under the original typification, the name ''Acacia'' would stay with the group of species currently recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Phenax
''Eucalyptus phenax'', commonly known as green dumosa mallee or white mallee, is a species of Mallee (habit), mallee that is Endemism, endemic to southern Australia. It has smooth bark, lance-shaped adult leaves, flower buds in groups of seven or nine, white flowers and cup-shaped to cylindrical fruit. Description ''Eucalyptus phenax'' is a mallee or shrub that typically grows to a height of and forms a lignotuber. It has smooth, creamy grey bark that is shed in ribbons. Young plants and coppice regrowth have egg-shaped to lance-shaped leaves that are long and wide. Adult leaves are the same glossy green on both sides, lance-shaped, long and wide on a Petiole (botany), petiole long. The flower buds are arranged in leaf wikt:axil, axils, usually in groups of seven or nine on an unbranched Peduncle (botany), peduncle long, the individual buds Sessility (botany), sessile or on Pedicel (botany), pedicels up to long. Mature buds are cylindrical to oval, long and wide with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
