Acacia Leiocalyx
''Acacia leiocalyx'' (black wattle, early flowering black wattle, lamb's tail wattle, curracabah) grows in Queensland, Australia and as far south as Sydney. It is widespread and common in eucalypt woodlands, especially on well-drained, shallow soils. It is short-lived and grows 6–7 metres (20–23 ft.) tall, with a trunk about 180 mm (7 inches) in diameter. Description This is a small ''Acacia'' tree with furrowed bark. It has sickle-shaped green leaves with prominent veins, with the bottom two joined near the base. Its flowers are yellow, in narrow spikes. Its seeds pods are narrow and rather curly and grow in loose bunches. It usually flowers from June to October. Taxonomy There were several closely related trees which used to all come under the name of ''Acacia cunninghamii'', but have been now identified as a number of separate species. The ''Acacia cunninghamii'' 'group' all have spiky inflorescences and large phyllodes. They are closely interrelated and taxono ...

Domin
Karel Domin (4 May 1882, Kutná Hora, Kingdom of Bohemia – 10 June 1953, Prague) was a Czech botanist and politician. After gymnasium school studies in Příbram, he studied botany at the Charles University in Prague, and graduated in 1906. Between 1911 and 1913 he published several important articles on Australian taxonomy. In 1916 he was named as professor of botany. Domin specialised in phytogeography, geobotany and plant taxonomy. He became a member at the Czechoslovak Academy of Sciences, published many scientific works and founded a botany institute at the university. The Domin scale, a commonly used means of classifying a standard area by the number of plant species found in that area, is named after him. In the academic year 1933-34 he was rector of Charles University and was one of the participants of a struggle for ancient academic insignia between the Czech and German universities of Prague (the ''insigniáda'') that resulted in street-fights and looting.

Leslie Pedley
Leslie Pedley (19 May 1930 – 27 November 2018)IPNILeslie Pedley/ref> was an Australian botanist who specialised in the genus ''Acacia''. He is notable for bringing into use the generic name ''Racosperma'', creating a split in the genus, which required some 900 Australian species to be renamed, because the type species of ''Acacia'', ''Acacia nilotica'', now ''Vachellia nilotica'', had a different lineage from the Australian wattles. However, the International Botanical Congress (IBC), held in Melbourne in 2011, ratified its earlier decision to retain the name ''Acacia'' for the Australian species, but to rename the African species. See also: ''Acacia'' and ''Vachellia nilotica'' regarding the dispute, anAPNIfor a brief history of the name, ''Racosperma''. In 2018, Japanese botanists Hiroyoshi Ohashi and Kazuaki K.

Australasian Virtual Herbarium
The ''Australasian Virtual Herbarium'' (AVH) is an online resource that allows access to plant specimen data held by various Australian and New Zealand herbaria. It is part of the Atlas of Living Australia (ALA), and was formed by the amalgamation of ''Australia's Virtual Herbarium'' and ''NZ Virtual Herbarium''. As of 12 August 2014, more than five million specimens of the 8 million and upwards specimens available from participating institutions have been databased. Uses This resource is used by academics, students, and anyone interested in research in botany in Australia or New Zealand, since each record tells all that is known about the specimen: where and when it was collected; by whom; its current identification together with the botanist who identified it; and information on habitat and associated species. ALA post processes the original herbarium data, giving further fields with respect to taxonomy and quality of the data. When interrogating individual specimen record ...

Acacia Cunninghamii Banks
''Acacia'', commonly known as the wattles or acacias, is a large genus of shrubs and trees in the subfamily Mimosoideae of the pea family Fabaceae. Initially, it comprised a group of plant species native to Africa and Australasia. The genus name is New Latin, borrowed from the Greek (), a term used by Pedanius Dioscorides, Dioscorides for a preparation extracted from the leaves and fruit pods of ''Vachellia nilotica'', the original type of the genus. In his ''Pinax'' (1623), Gaspard Bauhin mentioned the Greek from Dioscorides as the origin of the Latin name. In the early 2000s it had become evident that the genus as it stood was not Monophyly, monophyletic and that several divergent lineages needed to be placed in separate genera. It turned out that one lineage comprising over 900 species mainly native to Australia, New Guinea, and Indonesia was not closely related to the much smaller group of African lineage that contained ''A. nilotica''—the type species.

Sydney
Sydney ( ) is the capital city of the state of New South Wales, and the most populous city in both Australia and Oceania. Located on Australia's east coast, the metropolis surrounds Sydney Harbour and extends about towards the Blue Mountains to the west, Hawkesbury to the north, the Royal National Park to the south and Macarthur to the south-west. Sydney is made up of 658 suburbs, spread across 33 local government areas. Residents of the city are known as "Sydneysiders". The 2021 census recorded the population of Greater Sydney as 5,231,150, meaning the city is home to approximately 66% of the state's population. Estimated resident population, 30 June 2017. Nicknames of the city include the 'Emerald City' and the 'Harbour City'. Aboriginal Australians have inhabited the Greater Sydney region for at least 30,000 years, and Aboriginal engravings and cultural sites are common throughout Greater Sydney. The traditional custodians of the land on which modern Sydney stands are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalypt
Eucalypt is a descriptive name for woody plants with capsule fruiting bodies belonging to seven closely related genera (of the tribe Eucalypteae) found across Australasia: ''Eucalyptus'', '' Corymbia'', '' Angophora'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum''. Taxonomy For an example of changing historical perspectives, in 1991, largely genetic evidence indicated that some prominent ''Eucalyptus'' species were actually more closely related to ''Angophora'' than to other eucalypts; they were accordingly split off into the new genus ''Corymbia''. Although separate, all of these genera and their species are allied and it remains the standard to refer to the members of all seven genera ''Angophora'', ''Corymbia'', ''Eucalyptus'', ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' as "eucalypts" or as the eucalypt group. The extant genera ''Stockwellia'', ''Allosyncarpia'', ''Eucalyptopsis'' and ''Arillastrum'' comprise six k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phyllode
Phyllodes are modified petioles or leaf stems, which are leaf-like in appearance and function. In some plants, these become flattened and widened, while the leaf itself becomes reduced or vanishes altogether. Thus the phyllode comes to serve the purpose of the leaf. Some important examples are ''Euphorbia royleana'' which are cylindrical and '' Opuntia'' which are flattened. They are common in the genus ''Acacia'', especially the Australian species, at one time put in ''Acacia'' subg. ''Phyllodineae''. Sometimes, especially on younger plants, partially formed phyllodes bearing reduced leaves can be seen. The illustration (to the right) of ''Acacia suaveolens'' from ''Novae Hollandiae plantarum specimen'' shows the juvenile true leaves, together with the developing phyllodes, and the phyllodes of the mature plant. The genus, ''Daviesia'', in the family Fabaceae, is characterised in part by the plants having phyllodes. File:Acacia suaveolens 9064505997 9f14f5f117 o.jpg, ''Acacia ...

Acacia Concurrens
''Acacia concurrens'', commonly known as curracabah or black wattle, is a shrub native to Queensland in eastern Australia. Formerly known as ''Acacia cunninghamii'', the new name ''Acacia concurrens'' describes the converging primary veins on the phyllodes. It is very similar to Acacias such as ''Acacia leiocalyx'' and '' Acacia disparrima''. Description The shrub can grow as high as but is typically smaller. The glossy green phyllodes have an obliquely obovate shape with the lower margin that is almost straight. It has fissured and fibrous, grey-black coloured bark and stout, angular branchlets The phyllodes have a length of up to . It blooms between March and September producing rod shaped flowers are bright yellow that are found in pairs in the leaf axils. The flower-spikes are around in length. The linear, slightly moniliform, semicircular seed pods that form after flowering are in length. The pods contain brownish black seeds with an elliptic shape that are in length. T ...

Pulvinus
A pulvinus (pl. ''pulvini'') is a joint-like thickening at the base of a plant leaf or leaflet that facilitates growth-independent movement. Pulvini are common, for example, in members of the bean family Fabaceae (Leguminosae) and the prayer plant family Marantaceae. Pulvini may be present at the base of the Petiole (botany), leaf stalk or on its other end (Apex (leaf), apex), where the leaf is attached, or in a compound leaf at the place where the leaflets are joined to its Rachis#In botany, middle stem. They consist of a core of vascular tissue within a flexible, bulky cylinder of thin-walled Ground tissue#Parenchyma, parenchyma cells. A pulvinus is also sometimes called a geniculum (meaning a knee-like structure in Latin). Pulvinar movement is caused by changes in turgor pressure leading to a contraction or expansion of the parenchyma tissue. The response is initiated when sucrose is unloaded from the phloem into the apoplast. The increased sugar concentration in the apoplast d ...
