Pteris Platyzomopsis
''Pteris platyzomopsis'', synonym ''Platyzoma microphyllum'', is a species of fern in the family Pteridaceae. When placed in the genus ''Platyzoma'', it was the only species; the genus was sometimes placed in its own family, Platyzomaceae. The species is native to northern Australia, occurring in the Kimberley region of Western Australia, in the Northern Territory and Queensland, and in northern New South Wales, where it is considered endangered. Vernacular names include braid fern. Characteristics ''Pteris platyzomopsis'' is unusual among ferns in that it may display incipient heterospory. Microsporangia produce 32 microspores, each 71-101μm in diameter. Megasporangia produce 16 megaspores, each 163-183μm in diameter. Microspores produce a filamentous microgametophyte, which lacks rhizoids and gives rise only to antheridia. Megaspores produce spatulate megagametophytes with rhizoids, which produce archegonia. Megagametophytes may later produce antheridia, making them functi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mor ...

Flora Of Queensland
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. 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) ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Pteris
''Pteris'' (brake) is a genus of about 300 species of ferns in the subfamily Pteridoideae of the family Pteridaceae. They are native to tropical and subtropical regions, southward to New Zealand, Australia, and South Africa, north to Japan and North America. 78 species (35 endemic) are found in China. Some species of ''Pteris'' have considerable economic and ecological value, such as ''Pteris multifida'', ''Pteris ensiformis'', ''Pteris vittata'' can be used for ornamental purposes; as a hyperaccumulator, ''Pteris multifida'' and ''Pteris vittata'' can be used to control soil pollution. Many of them have linear frond segments, and some have sub-palmate division. Like other members of the Pteridaceae, the frond margin is reflexed over the marginal sorus, sori. The outermost layer is the single layered epidermis without stomata. The cortex is differentiated into outer and inner cortical region. The vascular cylinder is an wikt:amphiphloic, amphiphloic siphonostele. The term "brak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gleichenia
''Gleichenia'' is a genus of ferns. Its closest relative is the genus '' Stromatopteris'', restricted to New Caledonia. Description These ferns have creeping rhizomes. The compound eaves fork multiple times, with the final leaf lobes ending in a pinnate arrangement. The sori are found at the bottom of the leaves and are made of a few sporangia. They are not covered by an indusium (protective covering). The sori occur in a unique chamber in the laminar pits - a feature found only in this genus. Fossil record The fossil record indicates that this genus had emerged by the late Jurassic period, although it was far more common in the early Cretaceous period. There is some evidence that it may have emerged even earlier - in the upper Triassic period. There are, however, multiple genera in the fossil record that show a similar leaf branching pattern to ''Gleichenia'', which can make it difficult to determine the exact identity of a specimen that does not have adequately preserved f ...

Gleichenia Rupestris
''Gleichenia rupestris'' is a small fern growing in eastern Australia. Referred to as one of the coral ferns. The specific epithet ''rupestris'' refers to it being seen growing near rocks. A common plant, often seen growing under waterfalls, in swamps, under cliffs, on rocks and in tall open forest. It prefers high humidity and good levels of sunshine and moisture. It sometimes seen growing next to ''Gleichenia dicarpa'' and ''Gleichenia microphylla'', however those plants have a rough hairy stem, and the stem of ''Gleichenia rupestris'' is smooth and glossy. This plant first appeared in scientific literature in the ''Prodromus Florae Novae Hollandiae'' in the year 1810, authored by Robert Brown Robert Brown may refer to: Robert Brown (born 1965), British Director, Animator and author Entertainers and artists * Washboard Sam or Robert Brown (1910–1966), American musician and singer * Robert W.

Fern
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses 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 leaf, leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled Fiddlehead fern, 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 (plant), Polypodiidae) and eusporangiate ferns, the latter group including horsetails, Psilotaceae, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
