Orites Acicularis
''Orites acicularis'', commonly known as yellow bush, is an angiosperm endemic to Tasmania, Australia and is a member of the genus ''Orites'' within the family Proteaceae. The species was first described in 1810 by Scottish botanist Robert Brown in ''Transactions of the Linnean Society of London.'' Description ''Orites acicularis'' is a yellow-green coloured, woody, rounded shrub growing to approximately 1–1.5 m (3.28–4.92 ft) in height and 0.5–1 m (1.64–3.28 ft) in width, with many ascending branches. The leaves are of a conspicuous yellow-green colour; they are glabrous, sclerophyllous, approximately 10-35mm long, and rounded. They taper to a sharp point, which is typically more yellow than the rest of the leaf. The adaxial surface of the leaf has a shallow central groove, and the leaf margins are entire. Leaves attach to the woody stem by a 2–5 mm petiole. Flowering occurs in December, and presents upon a rachis which can be terminal or axill ...

Mount Wellington (Tasmania)
Mount Wellington (officially kunanyi / Mount Wellington ()) is a mountain in the southeast of Tasmania, Australia. It is the summit of the Wellington Range and is within Wellington Park reserve. Hobart, Tasmania's capital city, is located at the foot of the mountain. The mountain rises to above sea level and is frequently covered by snow, sometimes even in summer, and the lower slopes are thickly forested, but crisscrossed by many walking tracks and a few fire trails. There is also a sealed narrow road to the summit, about from Hobart central business district. An enclosed lookout near the summit has views of the city below and to the east, the Derwent estuary, and also glimpses of the World Heritage Area nearly west. From Hobart, the most distinctive feature of Mount Wellington is the cliff of dolerite columns known as the Organ Pipes. Geology The low-lying areas and foothills of Mount Wellington were formed by slow geological upsurge when the whole Hobart area was a lo ...

Diorite
Diorite ( ) is an intrusive igneous rock formed by the slow cooling underground of magma (molten rock) that has a moderate content of silica and a relatively low content of alkali metals. It is intermediate in composition between low-silica (mafic) gabbro and high-silica ( felsic) granite. Diorite is found in mountain-building belts (''orogens'') on the margins of continents. It has the same composition as the fine-grained volcanic rock, andesite, which is also common in orogens. Diorite has been used since prehistoric times as decorative stone. It was used by the Akkadian Empire of Sargon of Akkad for funerary sculptures, and by many later civilizations for sculptures and building stone. Description Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and sometimes pyroxene. The chemical composition of diorite is intermediate, between that of mafic gabbro and felsic grani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Cuticle
A plant cuticle is a protecting film covering the outermost skin layer (epidermis) of leaves, young shoots and other aerial plant organs (aerial here meaning all plant parts not embedded in soil or other substrate) that have no ''periderm''. The film consists of lipid and hydrocarbon polymers impregnated with wax, and is synthesized exclusively by the epidermal cells. Kolattukudy, PE (1996) Biosynthetic pathways of cutin and waxes, and their sensitivity to environmental stresses. In: Plant Cuticles. Ed. by G. Kerstiens, BIOS Scientific publishers Ltd., Oxford, pp 83-108 Description The plant cuticle is a layer of lipid polymers impregnated with waxes that is present on the outer surfaces of the primary organs of all vascular land plants. It is also present in the sporophyte generation of hornworts, and in both sporophyte and gametophyte generations of mosses The plant cuticle forms a coherent outer covering of the plant that can be isolated intact by treating plant tissue with ...

Tasmannia Lanceolata
''Tasmannia lanceolata'' ( syn. ''Drimys lanceolata''), commonly known as Tasmanian pepperberry or mountain pepper, is a shrub native to woodlands and cool temperate rainforest of south-eastern Australia. The shrub varies from 2 to 10 m high. The aromatic leaves are lanceolate to narrow-elliptic or oblanceolate, 4–12 cm long, and 0.7–2.0 cm wide, with a distinctly pale undersurface. Stems are quite red in colour. The small cream or white flowers appear in summer and are followed by black, globose, two-lobed berries 5–8 mm wide, which appear in autumn. There are separate male and female plants. Originally described by French botanist Jean Louis Marie Poiret, it gained its current name in 1969 by A.C. Smith.

Richea Sprengelioides
''Richea sprengelioides'' is a species of flowering plant in the family Ericaceae. It is one of the 11 species within the genus ''Richea'' that are endemic to Australia, of which 9 are found only in Tasmania. The species was first formally described by botanist Robert Brown in 1810 in ''Prodromus Florae Novae Hollandiae''. He gave it the name ''Cystanthe sprengelioides''. ">/sup> In 1867 Victorian Government Botanist Ferdinand von Mueller transferred the species to the genus ''Richea''. It is found throughout the mountainous regions of Tasmania. Description ''Richea sprengelioides'' can grow as an erect shrub up to 1.2m in height. Older stems are devoid of leaves but bear numerous angular scars. Its leaves follow the distinctive habit of its genus, sheathing the stem before curling away and tapering to a point. Its inflorescence is roughly 2 centimeters wide and tall, with some 20 flowers clustered together at the end of the stems. ''Richea sprengelioides'' in general is eas ...

Orites Revolutus
''Orites revolutus '', also known as narrow-leaf orites, is a Tasmanian endemic plant species in the family Proteaceae. Scottish botanist Robert Brown formally described the species in ''Transactions of the Linnean Society of London'' in 1810 from a specimen collected at Lake St Clair. Abundant in alpine and subalpine heath, it is a small to medium shrub tall, with relatively small, blunt leaves with strongly revolute margins. The white flowers grow on terminal spikes during summer. Being proteaceaous, ''O. revolutus'' is likely to provide a substantial food source for nectivorous animal species within its range. Description ''Orites revolutus'' grows as a spreading bush or an erect, woody shrub, usually in height. Branching is dense and the leaves are alternate up the stem. Leaf shape is narrow and fairly blunt at the apex, 7–20 mm long, 1-1.5 mm wide, with tightly revolute margins and a hairy surface on the underside. Flowering occurs in early to mid-summer with ...

Gleichenia Alpina
''Gleichenia alpina'', commonly known as alpine coral-fern, is a small fern species that occurs in Tasmania and New Zealand. It grows in alpine and subalpine areas with moist soils and is a part of the Gleichrniaceae family. The species was first formally described by botanist Robert Brown in 1810. Description ''Gleichenia alpina'' is a common native ground-fern that grows in boggy alpine and subalpine vegetation. It has the typical ''Gleichenia'' foliage, which is repeatedly dichotomously divided before ending in pinnate laminas. The distinctive feature is deep pouches densely covered with hairs on the underside of the pinnules. ''Gleichenia alpina'' is characterised by comparatively short frond axes and the dense orange-brown (becoming pale) scales that obscure the abaxial surface of the lamina. Its strongly pouched ultimate segments mean it can be confused only with ''G. dicarpa''. From that species, ''G. alpina'' can be distinguished by: the absence of stellate scales wi ...

Peat
Peat (), also known as turf (), is an accumulation of partially decayed vegetation or organic matter. It is unique to natural areas called peatlands, bogs, mires, moors, or muskegs. The peatland ecosystem covers and is the most efficient carbon sink on the planet, because peatland plants capture carbon dioxide (CO2) naturally released from the peat, maintaining an equilibrium. In natural peatlands, the "annual rate of biomass production is greater than the rate of decomposition", but it takes "thousands of years for peatlands to develop the deposits of , which is the average depth of the boreal orthernpeatlands", which store around 415 gigatonnes (Gt) of carbon (about 46 times 2019 global CO2 emissions). Globally, peat stores up to 550 Gt of carbon, 42% of all soil carbon, which exceeds the carbon stored in all other vegetation types, including the world's forests, although it covers just 3% of the land's surface. ''Sphagnum'' moss, also called peat moss, is one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
