Drosera Paradoxa
''Drosera paradoxa'' is a carnivorous plant in the genus ''Drosera'' and is endemism, endemic to the Northern Territory and Western Australia. It is a perennial plant, perennial herbaceous plant, herb with a woody stem that can grow as tall as . The leaves on the single terminal rosette (botany), rosette are erect or horizontal (with age) and held at the end of leaf shape, linear petiole (botany), petioles, which are typically 20–35 mm (approximately 1 inch) long at flowering time. The carnivorous leaves are leaf shape, sub-orbicular and small at 2.5–3 mm (approximately 1/10 inch) wide and 2–3 mm (approximately 1/10 inch) long. Inflorescences are long with pink or white flowers being produced on 50- to 70-flowered crowded racemes from July to September during the dry season.Lowrie, A. 1997''Drosera paradoxa'' (Droseraceae), a new species from northern Australia.''Nuytsia (journal), Nuytsia'', 11(3): 347–351.

Allen Lowrie
Allen Lowrie (10 October 1948 - 30 August 2021) was a Western Australian botanist. He was recognised for his expertise on the genera ''Drosera'' and '' Stylidium''.Council of Heads of Australasian HerbariaResources of Australian Herbaria: Western Australian Herbarium accessed 21 June 2013. Lowrie, originally a businessman and inventor, first experienced the carnivorous flora of Western Australia in the late sixties and studied it as an amateur. Over time, his hobby turned into a profession and Lowrie discovered and described numerous species (especially ''Drosera'', ''Byblis'' and ''Utricularia''), partly together with Neville Marchant. From 1987 to 1998 he published ''Carnivorous Plants of Australia ''Carnivorous Plants of Australia'' is a three-volume work on carnivorous plants by Allen Lowrie. The three tomes were published in 1987, 1989, and 1998, by University of Western Australia Press. An entirely updated three-volume work by Lowrie w ...'' in three volumes; a fourth i ...

Arnhem Land
Arnhem Land is a historical region of the Northern Territory of Australia, with the term still in use. It is located in the north-eastern corner of the territory and is around from the territory capital, Darwin. In 1623, Dutch East India Company captain Willem Joosten van Colster (or Coolsteerdt) sailed into the Gulf of Carpentaria and Cape Arnhem is named after his ship, the ''Arnhem'', which itself was named after the city of Arnhem in the Netherlands. The area covers about and has an estimated population of 16,000, of whom 12,000 are Aboriginal and Torres Strait Islander people. Two regions are often distinguished as East Arnhem (Land) and West Arnhem (Land), and North-east Arnhem Land is known to the local Yolŋu people as Miwatj. The region's service hub is Nhulunbuy, east of Darwin, set up in the early 1970s as a mining town for bauxite. Other major population centres are Yirrkala (just outside Nhulunbuy), Gunbalanya (formerly Oenpelli), Ramingining, and Maningrida. ...

Eudicots Of Western Australia
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants mainly characterized by having two seed leaves upon germination. The term derives from Dicotyledons. Traditionally they were called tricolpates or non-magnoliid dicots by previous authors. The botanical terms were introduced in 1991 by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Numerous familiar plants are eudicots, including many common food plants, trees, and ornamentals. Some common and familiar eudicots include sunflower, dandelion, forget-me-not, cabbage, apple, buttercup, maple, and macadamia. Most leafy trees of midlatitudes also belong to eudicots, with notable exceptions being magnolias and tulip trees which belong to magnoliids, and ''Ginkgo biloba'', which is not an angiosperm.

Caryophyllales Of Australia
Caryophyllales ( ) is a diverse and heterogeneous order of flowering plants that includes the cacti, carnations, amaranths, ice plants, beets, and many carnivorous plants. Many members are succulent, having fleshy stems or leaves. The betalain pigments are unique in plants of this order and occur in all its families with the exception of Caryophyllaceae and Molluginaceae. Description The members of Caryophyllales include about 6% of eudicot species. This order is part of the core eudicots. Currently, the Caryophyllales contains 37 families, 749 genera, and 11,620 species The monophyly of the Caryophyllales has been supported by DNA sequences, cytochrome c sequence data and heritable characters such as anther wall development and vessel-elements with simple perforations. Circumscription As with all taxa, the circumscription of Caryophyllales has changed within various classification systems. All systems recognize a core of families with centrospermous ovules and seeds. More ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnivorous Plants Of Australia
''Carnivorous Plants of Australia'' is a three-volume work on carnivorous plants by Allen Lowrie. The three tomes were published in 1987, 1989, and 1998, by University of Western Australia Press. An entirely updated three-volume work by Lowrie was published by Redfern Natural History Productions in December 2013 as ''Carnivorous Plants of Australia Magnum Opus''.Lowrie, A. 2013. ''Carnivorous Plants of Australia Magnum Opus - Volume Three''. Redfern Natural History Productions, Poole. . Content The first volume deals exclusively with tuberous sundews (genus ''Drosera''). The second is devoted to pygmy sundews, but also includes three tuberous species described since the publication of the first volume, as well as two other sundews that do not fit elsewhere ('' D. glanduligera'' and '' D. hamiltonii''). The final volume includes the remaining sundews of Australia, together with native species of ''Aldrovanda'', ''Byblis'', ''Cephalotus'', ''Nepenthes'', and ''Utricular ...

Taxonomy Of Drosera
The genus ''Drosera'' was divided in 1994 by Seine & Barthlott into three subgenera and 11 sections on the basis of morphological characteristics. Discovery and description of new species has been occurring since the 10th century, and as recently as the 1940s barely more than 80 species were known. In recent years, Australian Allen Lowrie has done extensive work in the genus, particularly in describing numerous new species from Australia. His classification of the genus was replaced by Jan Schlauer's work in 1996, although the correct classification is still disputed. ''Drosera'' subg.

Drosera Petiolaris
''Drosera petiolaris'' is a carnivorous plant in the genus ''Drosera'' and is the eponymous species of the ''petiolaris'' species complex, which mostly refers to the entire subgenus '' Lasiocephala''. It is native to Northern Australia, including the northern regions of Western Australia, the Northern Territory, and Queensland, and New Guinea; this distribution is the largest in the subgenus and the only that extends beyond Australia. Its leaves are arranged in a compact basal rosette with long, narrow petioles emerging from the center of the rosette. Carnivorous leaves are held at the end of the petiole with long retentive glands.Lowrie, A. 1990The ''Drosera petiolaris'' complex.''

Conservation Status
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use. International systems IUCN Red List of Threatened Species The IUCN Red List of Threatened Species is the best known worldwide conservation status listing and ranking system. Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmentation. Also included are species that have gone ext ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Type
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. The length of growing seasons and period in which they take place vary according to geographical location, and may not correspond to the four traditional seasonal divisions of the year. With respect to the traditional seasons, annual plants are generally categorized into summer annuals and winter annuals. Summer annuals germinate during spring or early summer and mature by autumn of the same year. Winter annuals germinate during the autumn and mature during the spring or summer of the following calendar year. One seed-to-seed life cycle for an annual plant can occur in as little as a month in some species, though most last several months. Oilseed rapa can go from seed-to-seed in about five weeks under a bank of fluorescent lamps. This style of growing is often used in classrooms for education. Many desert annuals are therophytes, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
