Description ''Commersonia densiflora'' is a dense, low-growing shrub that typically grows to high and wide, its new growth densely covered with white, star-shaped hairs. The leaves are pinnate, elliptic to narrowly oblong, long and wide on a petiole long with stipules long at the base. The edges of the leaves are rolled under and wavy with irregular teeth, the upper surface has prominent veins, and both surfaces are densely covered with white, star-shaped hairs. The flowers are arranged in dense clusters of 20 to 100 or more on the ends of branches on a peduncle long, each flower on a pedicel long with a bract long at the base.

Australian National Botanic Gardens
The Australian National Botanic Gardens (ANBG) is a heritage-listed botanical garden located in , Canberra, in the Australian Capital Territory, Australia. Established in 1949, the Gardens is administered by the Australian Government's Department of Agriculture, Water and the Environment. The botanic gardens was added to the Commonwealth Heritage List on 22 June 2004. The botanic gardens is the largest living collection of native Australian flora. The mission of the ANBG is to "study and promote Australia's flora". The gardens maintains a wide variety of botanical resources for researchers and cultivates native plants threatened in the wild. The herbarium code for the Australian National Botanic Gardens is ''CANB''. History When Canberra was being planned in the 1930s, the establishment of the gardens was recommended in a report in 1933 by the Australian Capital Territory Advisory Council. In 1935, The Dickson Report set forth a framework for their development. A large site fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staminode
In botany, a staminode is an often rudimentary, sterile or abortive stamen, which means that it does not produce pollen.Jackson, Benjamin, Daydon; ''A Glossary of Botanic Terms with their Derivation and Accent''; Published by Gerald Duckworth & Co. London, 4th ed 1928 Staminodes are frequently inconspicuous and stamen-like, usually occurring at the inner whorl of the flower, but are also sometimes long enough to protrude from the corolla. Sometimes, the staminodes are modified to produce nectar, as in the witch-hazel ''(Hamamelis)''.jin lu mei shu. Hamamelis Linnaeus, Sp. Pl. 1: 124. 1753. Flora of China 9: 32. 2003 Staminodes can be a critical characteristic for differentiating between species, for instance in the orchid genus ''Paphiopedilum'', and among the penstemons. In the case of cannas, the petals are inconsequential and the staminodes are refined into eye-catching petal-like replacements. A spectacular example of staminode is given by ''Couroupita guianensis ''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Avon Wheatbelt
The Avon Wheatbelt is a bioregion in Western Australia. It has an area of . It is considered part of the larger Southwest Australia savanna ecoregion. Geography The Avon Wheatbelt bioregion is mostly a gently undulating landscape with low relief. It lies on the Yilgarn craton, an ancient block of crystalline rock, which was uplifted in the Tertiary and dissected by rivers. The craton is overlain by laterite deposits, which in places have decomposed into yellow sandplains, particularly on low hills. Steep-sided erosional gullies, known as breakaways, are common.

Shark Bay
Shark Bay () is a World Heritage Site in the Gascoyne region of Western Australia. The area is located approximately north of Perth, on the westernmost point of the Australian continent. UNESCO's listing of Shark Bay as a World Heritage Site reads: The bay features Australia's most abundant marine ecosystems. It is a popular fishing spot. History The record of Indigenous Australians, Australian Aboriginal occupation of Shark Bay extends to years Before Present, BP. At that time most of the area was dry land, and rising sea levels flooded Shark Bay between BP and BP. A considerable number of Aboriginal midden sites have been found, especially on Peron Peninsula and Dirk Hartog Island, which provide evidence of some of the foods gathered from the waters and nearby land areas. An expedition led by Dirk Hartog happened upon the area in 1616, becoming the second group of Europeans known to have visited Australia, after the crew of ''Duyfken'' under Willem Janszoon had visi ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ferdinand Von Mueller
Baron Sir Ferdinand Jacob Heinrich von Mueller, (; 30 June 1825 – 10 October 1896) was a German-Australian physician, geographer, and most notably, a botanist. He was appointed government botanist for the then colony of Victoria, Australia by Governor Charles La Trobe in 1853, and later director of the Royal Botanic Gardens in Melbourne. He also founded the National Herbarium of Victoria. He named many Australian plants. Early life Mueller was born at Rostock, in the Grand Duchy of Mecklenburg-Schwerin. After the early death of his parents, Frederick and Louisa, his grandparents gave him a good education in Tönning, Schleswig. Apprenticed to a chemist at the age of 15, he passed his pharmaceutical examinations and studied botany under Professor Ernst Ferdinand Nolte (1791–1875) at Kiel University. In 1847, he received his degree of Doctor of Philosophy from Kiel for a thesis on the plants of the southern regions of Schleswig. Mueller's sister Bertha had been advi ...

James Drummond (botanist)
James Drummond (late 1786 or early 1787 – 26 March 1863) was an Australian botanist and naturalist who was an early settler in Western Australia. Early life James Drummond was born in Inverarity, near Forfar, Angus, Scotland, the eldest son of Thomas Drummond, a gardener and botanist. His younger brother Thomas Drummond (1793–1835) was also a botanist. The latter emigrated to Cuba and died there. Both brothers originally worked with their father on the Fothringham estate in Inverarity. He was baptised on 8 January 1787. His father, Thomas Drummond, was a gardener at Fotheringham estate. Little is known of his early life, but he certainly followed the usual course of apprenticeship leading to his "qualification" as a gardener. In 1808, he was employed by Mr Dickson (most probably George Dickson of Leith Walk, Edinburgh). In the mid-1808, Drummond (aged 21) he was appointed curator of the botanic garden that was being established by the Cork Institution, in the city ...

Moscow Society Of Naturalists
Moscow Society of Naturalists () is one of Russia's oldest learned societies. In 1805 it was founded as the Imperial Society of Naturalists of Moscow () under the auspices of two noblemen, Mikhail Muravyov and Alexis Razumovsky, by Johann Fischer von Waldheim in 1805. Princess Zenaǐde Wolkonsky made a gift of her own library to the society.'' Ю. В. Чайковский''Старейшее общество и его библиотека.Москва научная. — М.: Янус-К, 1997. — С. 392—415. The tasks of the society were considered to be the development of general scientific problems of natural science, the study of the natural resources of Russia, including "the discovery of such works, which could constitute a new branch of Russian trade." From the very beginning of its existence, the society began organizing expeditions and excursions to study the nature of Russia and collect natural history collections. MOIP organized expeditions to explore Alta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
