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 ...

Astelia Chathamica
''Astelia chathamica'', the Chatham Islands kakaha, Maori flax, or silver spear, is a species of flowering plant in the recently named family Asteliaceae. It is an evergreen silver-green perennial from the Chatham Islands of New Zealand, growing to about tall. Forming a large clump of sword-shaped leaves, it produces small green flowers and red berries (the latter only on the female plant). It grows best in partial shade and in fertile and well-drained soil with moderate water. The plant is hardy down to , but the foliage may be damaged by frost, so in colder areas the plant may require some winter protection. In cultivation in the UK, this plant has gained the Royal Horticultural Society The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (Nor ...’s Award of Garden Merit. References ...

Carpha Alpina
''Carpha alpina'', commonly known as small flower-rush, is a tufted perennial sedge from the family Cyperaceae. It is found primarily in south-east Australia and both islands of New Zealand, but also in Papua New Guinea. Description ''Carpha alpina'' grows as a short rhizomatous tufted perennial sedge. It has rigid, striated culms that are glabrous and can grow between 2-10 cm tall and 0.7-1.5 mm wide. The numerous grey-green or red-green leaf-blades are stiff and flattened, with a yellow-brown sheath and a width ranging from 0.5-2 mm. The inflorescence is made up of 1-3 loose clusters ranging from 1-10 cm long with singular or paired bracts slightly longer than the inflorescence. The spikelets are between 8-10 mm long and arranged in clusters of 2-10. The brown, acute and keeling glumes are separated into upper and lower parts, with the lowest 2 or 3 empty and half the size of the upper glumes. The upper glumes are larger - 8-9 mm long, with a bristlelike glume above; t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empodisma Minus
''Empodisma minus'', commonly known as (lesser) wire rush or spreading rope-rush, is a perennial evergreen belonging to the southern-hemisphere family of monocotyledons called the Restionaceae. The Latin name ''Empodisma minus'' translates to “tangle-foot” “small”. ''E. minus'' is found from Queensland to South Australia, Tasmania and throughout New Zealand south of 38 ° latitude, or the central north island. Its current conservation status is “Least concerned”. In 2012 the new species '' Empodisma robustum'' was described in New Zealand, with what was previously described as ''E. minus'' from the lowland raised bogs of Waikato and Northland now being re-classified as ''E. robustum''. ''E. minus'' remains an important peatformer in the south of New Zealand and in high altitude peatlands. Description The stems are 15–200 cm long, numerously branched, semi-terete and dark green to dark brown in colour. The stem keeps upright when short, yet becomes procumbent wh ...

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 ...

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 ...

Dioecious Species
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raceme
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...
