Gleichenia Dicarpa
''Gleichenia dicarpa'', commonly known as pouched coral fern or tangle fern, is a small fern of the family Gleicheniaceae found in eastern Australia, New Caledonia and New Zealand. It forms tangled thickets in wet places such as swamps and riverbanks. Taxonomy Collected by Joseph Banks and Daniel Solander in November 1769 at Mercury Bay in New Zealand, ''G. dicarpa'' appeared in the 1810 work ''Prodromus Florae Novae Hollandiae'', authored by prolific botanist Robert Brown. Its genus name honours the German botanist W.F. von Gleichen, and its species name is Ancient Greek for "two fruit". Common names in New Zealand include tangle fern, Spider fern, and swamp umbrella fern. Australian common names include pouched coral fern, and wiry coral fern. The taxonomy of ''G. dicarpa'' is more complicated than previously thought; a genetic study of the DNA of Gleicheniaceae from New Zealand and Tasmania indicate that a smaller shorter-branched "upland" form from New Zealand is in fact ...

Ferns Of New Zealand
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.

Flora Of Victoria (Australia)
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 Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pioneer Species
Pioneer species are hardy species that are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by wildfire. Pioneer flora Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants.LICHEN BIOLOGY AND THE ENVIRONMENT, LICHENS OF NORTH AMERICA, Sylvia and Stephen Sharnoff/ref> Since some uninhabited land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing Diazotroph, nitrogen-fixing bacteria, and leaves that employ transpiration. Note that they are often photosynthetic plants, as no other source of energy (such as other species) except light energy is often available in the early stages of succession, thus making it less likely for a pioneer species to be non-photosynthetic. The plants that are often pioneer species also tend to be wind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetlands Of New Zealand
New Zealand has several notable wetlands but 90% of wetland areas have been lost following European settlement. The Resource Management Act 1991, the major Act of Parliament determining land use, defines wetlands as "permanently or intermittently wet areas, shallow water, and land water margins that support a natural ecosystem of plants and animals that area adapted to wet conditions". The Ramsar Convention, an international conservation agreement for wetlands to which New Zealand signed up to in 1971, has a wider definition of wetland. Since the mid-19th century, New Zealand has lost about 90% of its wetland areas due to draining for farming. Many remaining wetlands are also degraded due to pollution, grazing, drainage and presence of invasive plants. In the late 20th and early 21st century, efforts have been made towards wetland conservation. Ramsar sites The Department of Conservation currently administers seven Ramsar sites protected under the Ramsar Convention, covering a ...

Rhizome
In botany and dendrology, a rhizome (; , ) is a modified subterranean plant stem that sends out roots and shoots from its nodes. Rhizomes are also called creeping rootstalks or just rootstalks. Rhizomes develop from axillary buds and grow horizontally. The rhizome also retains the ability to allow new shoots to grow upwards. A rhizome is the main stem of the plant that runs underground horizontally. A stolon is similar to a rhizome, but a stolon sprouts from an existing stem, has long internodes, and generates new shoots at the end, such as in the strawberry plant. In general, rhizomes have short internodes, send out roots from the bottom of the nodes, and generate new upward-growing shoots from the top of the nodes. A stem tuber is a thickened part of a rhizome or stolon that has been enlarged for use as a storage organ. In general, a tuber is high in starch, e.g. the potato, which is a modified stolon. The term "tuber" is often used imprecisely and is sometimes applied to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
