Olearia Microphylla
''Olearia microphylla'', commonly known as snow bush, small-leaved daisy-bush or twiggy daisy-bush, is a species of flowering plant in the family Asteraceae and is endemic to eastern Australia. It is a shrub with spatula-shaped leaves with the edges rolled under, and white and yellow, daisy-like inflorescences. Description ''Olearia microphylla'' is a shrub that typically grows to a height of up to . Its leaves are spatula-shaped, long and wide and more or less sessile, the upper surface pimply, the lower surface covered with greyish, woolly hairs and the edges rolled under. The heads or daisy-like "flowers" are arranged singly on the ends of side branches and are in diameter and sessile. Each head has six to eight white ray florets surrounding four to eight yellow disc florets. Flowering occurs from June to October and the fruit is a glandular achene, the pappus with 32 to 47 bristles. Taxonomy Snow bush was first formally described in 1804 by Étienne Pierre Ventenat who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Mountain (Australian Capital Territory)
Black Mountain, also known as Galambary to the Ngunnawal people, is a small mountain with an elevation of that is situated to the west of the Canberra central business district on the northern shore of Lake Burley Griffin, in the Australian Capital Territory of Australia. Black Mountain is protected from development by the Canberra Nature Park and is predominantly covered in native bushland and is a haven to native wildlife. Location and features The mountain is located west of the main campus of the Australian National University and, together with the ridge, forms a natural west and northwestern boundary for Canberra city. Black Mountain rises above the water level of Lake Burley Griffin that lies at its base.

Gland (botany)
In plants, a gland is defined functionally as a plant structure which secretes one or more products. This may be located on or near the plant surface and secrete externally, or be internal to the plant and secrete into a canal or reservoir. Examples include glandular hairs, nectaries, hydathodes, and the resin canals in Pinus. Notable examples Salt glands of the mangrove The salt glands of mangroves such as '' Acanthus'', ''Aegiceras'', ''Aegialitis'' and ''Avicennia'' are a distinctive multicellular trichome, a glandular hair found on the upper leaf surface and much more densely in the abaxial indumentum. On the upper leaf surface they are sunken in shallow pits, and on the lower surface they occur scattered among long nonglandular hairs composed of three or four cells. Development of the glands resembles that of the nonglandular hairs until the three-celled stage, when the short middle stalk cell appears. The salt gland continues to develop to produce two to four vacuola ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Queensland
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] |

Asterales Of Australia
Asterales () is an order of dicotyledonous flowering plants that includes the large family Asteraceae (or Compositae) known for composite flowers made of florets, and ten families related to the Asteraceae. While asterids in general are characterized by fused petals, composite flowers consisting of many florets create the false appearance of separate petals (as found in the rosids). The order is cosmopolitan (plants found throughout most of the world including desert and frigid zones), and includes mostly herbaceous species, although a small number of trees (such as the ''Lobelia deckenii'', the giant lobelia, and ''Dendrosenecio'', giant groundsels) and shrubs are also present. Asterales are organisms that seem to have evolved from one common ancestor. Asterales share characteristics on morphological and biochemical levels. Synapomorphies (a character that is shared by two or more groups through evolutionary development) include the presence in the plants of oligosaccharide ...

Olearia
''Olearia'', most commonly known as daisy-bush, is a genus of flowering plants belonging to the family Asteraceae, the largest of the flowering plant families in the world. Olearia are found in Australia, New Guinea and New Zealand. The genus includes herbaceous plants, shrubs and small trees. The latter are unusual among the Asteraceae and are called tree daisies in New Zealand. All bear the familiar daisy-like composite flowerheads in white, pink, mauve or purple. Description Plants in the genus ''Olearia'' are shrubs of varying sizes, characterised by a composite flower head arrangement with single-row ray florets enclosed by small overlapping bracts arranged in rows. The flower petals are more or less equal in length. The centre of the bi-sexual floret is disc shaped and may be white, yellowish or purplish, generally with 5 lobes. Flower heads may be single or clusters in leaf axils or at the apex of branchlets. Leaves may be smooth, glandular or with a sticky secretion. T ...

Eucalyptus Sclerophylla
''Eucalyptus sclerophylla'', known as the scribbly gum, is a tree native to eastern Australia. Very similar to the related Scribbly Gum (''E. haemastoma''), a better known tree. The best way of distinguishing the species is the smaller hemispherical to pear shaped gumnuts of ''Eucalyptus sclerophylla'', being 0.6 cm by 0.6 cm in size. Flower buds are also smaller. ''sclerophylla'' literally means ''hard leaf''. Both species have hard leaves, but Eucalyptus sclerophylla's leaves are particularly hard edged. Occurring on the poorer sandstone soils in mid to high rainfall areas. Around Sydney it often occurs on the higher ridges, where the soil is drier and less fertile. It ranges north from Jervis Bay, to near the Watagan district near Newcastle Newcastle usually refers to: *Newcastle upon Tyne, a city and metropolitan borough in Tyne and Wear, England *Newcastle-under-Lyme, a town in Staffordshire, England *Newcastle, New South Wales, a metropolitan area in Australia, ...

Eucalyptus Sieberi
''Eucalyptus sieberi'', commonly known as the silvertop ash or black ash, is a species of medium-sized to tall tree that is endemic to south-eastern Australia. It has rough bark on the trunk and the base of larger branches, smooth bark above, lance-shaped to curved adult leaves, flower buds in groups of seven to fifteen, white flowers and barrel-shaped or conical fruit. Description ''Eucalyptus sieberi'' is a tree that typically grows to a height of but does not form a lignotuber. It has rough bark on the trunk and the larger branches, smooth, white to yellow bark above. The rough bark is thin and flaky on younger trees, but becomes thick and dark grey to black and furrowed with age. Young plants have egg-shaped to lance-shaped or curved, bluish green to glaucous leaves that are long and wide. Adult leaves are the same shade of glossy green on both sides, lance-shaped to curved, long and wide on a petiole long. The flower buds are arranged in leaf axils in groups of betwe ...

Botanical Nomenclature
Botanical nomenclature is the formal, scientific naming of plants. It is related to, but distinct from Alpha taxonomy, taxonomy. Plant taxonomy is concerned with grouping and classifying plants; botanical nomenclature then provides names for the results of this process. The starting point for modern botanical nomenclature is Carl Linnaeus, Linnaeus' ''Species Plantarum'' of 1753. Botanical nomenclature is governed by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN''), which replaces the ''International Code of Botanical Nomenclature'' (''ICBN''). Fossil plants are also covered by the code of nomenclature. Within the limits set by that code there is another set of rules, the ''International Code of Nomenclature for Cultivated Plants, International Code of Nomenclature for Cultivated Plants (ICNCP)'' which applies to plant cultivars that have been deliberately altered or selected by humans (see cultigen). History and scope Botanical nomenclature has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Pierre Ventenat
Étienne Pierre Ventenat (1 March 1757 – 13 August 1808) was a French botanist born in Limoges. He was the brother of naturalist Louis Ventenat (1765–1794). While employed as director of the ecclesiastic library Sainte-Geneviève in Paris, Ventenat took a trip to England. Here he investigated the country's botanical gardens, inspiring him to pursue a vocation in sciences. Following his time at library he became an active botanist, studying under and collaborating with botanist Charles Louis L'Héritier de Brutelle (1746–1800). In 1795 he was elected a member of the ''Institut national des sciences et des arts'', later known as the ''Académie des sciences''. In 1794 he wrote a treatise on the principles of botany titled ''Principes de botanique, expliqués au Lycée républicain par Ventenat''. After publication he became so disappointed with its mediocrity that he reportedly made efforts to procure all copies of the book and have them destroyed. In 1798 he published a Fren ...

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
