Richea Scoparia
''Richea scoparia (formerly known as R. angustifolia)'', is a wide spread Tasmanian endemic plant. The genus ''Richea,'' forms part of the Ericaceae (formerly Epacridaceae) family, which are commonly heath-like shrubs. The name refers to the erect bushy growth habit, described as a broom-like shrub, most commonly referred to as the honey bush or simply scoparia to many bushwalkers. Description ''Richea scoparia'' is 1-3m high and commonly grows in wind-swept regions of mountains. The leaves persist for a number of years, even when dead. Leaves are crowded, sharp pointed, linear-lanceolate with a broad sheathing base, 3-6cm long. Inflorescences are terminal spikes 4-12cm in varying colours of orange, yellow, red, pink or white, flowering in January- March. Flowers with caps of joined petals, which a deciduous, exposing 5mm long stamens and a short style. Hybrid ''Richea scoparia'' forms a hybrid species with ''Richea pandanifolia''. The hybrid species, Richea curtisiae' is rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Field National Park
Mount Field National Park is a national park in Tasmania, Australia, 64 km northwest of Hobart. The landscape ranges from eucalyptus temperate rainforest to alpine moorland, rising to 1,434 metres (4,705 ft) at the summit of Mount Field West. History Mount Field National Park was founded in 1916, making it, along with Freycinet National Park, Tasmania's oldest national park. The area around Russell Falls has been protected for its natural beauty since 1885, when it was set aside as Tasmania's first nature reserve. The last known wild thylacine was captured in the region in 1933. The reserve was called "National Park" before 1946, but was officially renamed to its present name in 1947. Etymology Mount Field National Park was named for Judge Barron Field, who visited Tasmania as an itinerant judge in 1819 and 1821. Geology During the Pleistocene period, a snowfield covered the top of the Mount Field plateau and fed glaciers in the surrounding valleys. A large, 12&nb ...

Richea Pandanifolia
''Richea pandanifolia'', the pandani or giant grass tree, is a distinctive endemic Tasmanian angiosperm. It is dicot of the family Ericaceae and is found in central, western and south west Tasmania. It is a favourite among hikers and nature lovers. Description ''Richea pandanifolia'' can be described as an erect tree or shrub. It grows from in height. While it usually grows from just one stem, it can sometimes be branched. This branching occurs in the lowland subspecies as well as in damaged alpine plants. The species has strap-like leaves that taper to points and can grow up to long. These are dense and form from terminus branches. As the leaves age they are persistent, meaning that they remain on the plant. Young leaves are green in colour but as they age they become a greyish brown. The margins of these leaves are serrated and can cut human skin. Inflorescences emerge from the leaf axils on structures called panicles (branched inflorescence) which can grow up to long. ...

Ericales Of Australia
The Ericales are a large and diverse order of dicotyledons. Species in this order have considerable commercial importance including for tea, persimmon, blueberry, kiwifruit, Brazil nuts, argan, and azalea. The order includes trees, bushes, lianas, and herbaceous plants. Together with ordinary autophytic plants, the Ericales include chlorophyll-deficient mycoheterotrophic plants (e.g., '' Sarcodes sanguinea'') and carnivorous plants (e.g., genus ''Sarracenia''). Many species have five petals, often grown together. Fusion of the petals as a trait was traditionally used to place the order in the subclass Sympetalae. Mycorrhizal associations are quite common among the order representatives, and three kinds of mycorrhiza are found exclusively among Ericales (namely, ericoid, arbutoid and monotropoid mycorrhiza). In addition, some families among the order are notable for their exceptional ability to accumulate aluminum. Ericales are a cosmopolitan order. Areas of distribution of fa ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sclerophyll
Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat. The plants feature hard leaf, leaves, short Internode (botany), internodes (the distance between leaves along the stem) and leaf orientation which is parallel or oblique to direct sunlight. The word comes from the Greek ''sklēros'' (hard) and ''phyllon'' (leaf). The term was coined by Andreas Franz Wilhelm Schimper, A.F.W. Schimper in 1898 (translated in 1903), originally as a synonym of xeromorph, but the two words were later differentiated. Sclerophyllous plants occur in many parts of the world, but are most typical of areas with low rainfall or seasonal droughts, such as Australia, Africa, and western North and South America. They are prominent throughout Flora of Australia, Australia, parts of Flora of Argentina, Argentina, the Cerrado biogeographic region of Geography of Bolivia, Bolivia, Geography of Paraguay, Paraguay and Flora of Brazil, Brazil, and in the Mediterranean forests, woo ...

Montane Ecosystems
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid Speciation
Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare. With DNA analysis becoming more accessible in the 1990s, hybrid speciation has been shown to be a somewhat common phenomenon, particularly in plants. In botanical nomenclature, a hybrid species is also called a nothospecies. Hybrid species are by their nature polyphyletic. Ecology A hybrid may occasionally be better fitted to the local environment than the parental lineage, and as such, natural selection may favor these individuals. If reproductive isolation is subsequently achieved, a separate species may arise. Reproductive isolation may be genetic, ecological, behavioral, spatial, or a combination of these. If reproductive isolation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
