Rhizanthes
''Rhizanthes'' is a genus of four species of parasitic flowering plants in the family Rafflesiaceae. They are without leaves, stems, roots, or photosynthetic tissue, and grow within the roots of a few species of ''Tetrastigma'' vines. The genus is limited to the tropical forests of Southeast Asia. The flowers of ''Rhizanthes'' are very large, they vary from 14 to 43 cm in diameter. At least one species of ''Rhizanthes'', ''Rh. lowii'', is endothermic. Names The Latin name derives from the compound of the Ancient Greek words ῥίζα (pronounced ''rhíza''), meaning 'root', with the word ἄνθος ( ''anthos'') meaning 'flower'. 'Malay' vernacular names used for ''Rhizanthes zippelii'' according to Betty Molesworth Allen in 1967 were ''bunga pakma'' and ''bunga padma'', presumably, with the taxonomic changes, those names could actually refer to any species except ''Rh. zippelii''. The word ''bunga'' means flower; both names are shared by plants in the related genus ''Ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizanthes Lowii
''Rhizanthes lowii'' is a species of parasitic flowering plant without leaves, stems, roots, or photosynthetic tissue. It grows on the roots of the ''Tetrastigma'' vine. It includes the specimens with the largest measured flowers in '' Rhizanthes'', from 25 to 43 cm across. They are endothermic, not only producing their own heat, but they also have the rare ability to regulate their own temperature. Taxonomy ''Rhizanthes lowii'' was originally described by Odoardo Beccari as ''Brugmansia lowii'' in 1868, being the second of such ''Brugmansia'' species (The name ''Brugmansia'' is now used for a Solanaceous genus related to Datura). Bénédict Pierre Georges Hochreutiner recombined the taxon in 1930 to a new genus, ''Mycetanthe'', but Hermann Harms recombined the taxon again in 1934, to give it its present name. Distribution It was first collected on a little islet (in a river?) near the Malaysian town of Limbang, almost at the border of Brunei. Originally, the species wa ...

Rhizanthes Zippelii
''Rhizanthes zippelii'' is a species of parasitic flowering plant without leaves, stems, roots, or photosynthetic tissue. Its flowers bud out of the roots of the ''Tetrastigma'' vine. It is found in the tropical rainforests of Java. The flowers are reddish-brown, with long hanging tips, and are from 12 to 29 cm across. Taxonomy ''Rhizanthes zippelii'' was first described as ''Brugmansia zippelii'' by Carl Ludwig Blume in Java in 1828, placed in a monotypic genus. A second species, ''B. lowii'', followed, described by Odoardo Beccari in 1868. ''B. bakhuizenii'' was the third species, named by Emil Johann Lambert Heinricher after his 1903/04 trip to the island for a taxon with a different flower colour on Java. Bénédict Pierre Georges Hochreutiner recombined the taxon in 1930 to another genus, ''Mycetanthe'', but then a few years later in 1934 Édouard Spach moved the species to another genus, ''Rhizanthes'', as it is still classified in today.

Rafflesiaceae
The Rafflesiaceae are a family of rare parasitic plants comprising 36 species in 3 genera found in the tropical forests of east and southeast Asia, including '' Rafflesia arnoldii'', which has the largest flowers of all plants. The plants are endoparasites of vines in the genus '' Tetrastigma'' ( Vitaceae) and lack stems, leaves, roots, and any photosynthetic tissue. They rely entirely on their host plants for both water and nutrients, and only then emerge as flowers from the roots or lower stems of the host plants. Description Flowers Rafflesiaceae flowers mimic rotting carcasses in scent, color, and texture to attract their pollinators, carrion flies. For this reason, some flowers of the family '' Rafflesia'' are nicknamed "corpse flowers". Most members of Rafflesiaceae possess a large, bowl-shaped floral chamber formed by a perianth tube and a diaphragm. This diaphragm is the opening for carrion fly pollinators and is surrounded by attractive sterile organs. Flowers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rafflesia
''Rafflesia'' () is a genus of parasitic flowering plants in the family Rafflesiaceae. The species have enormous flowers, the buds rising from the ground or directly from the lower stems of their host plants; one species has the largest flowers in the world. Plants of the World Online lists up to 41 species from this genus, all of them are found throughout Southeast Asia. Western Europeans first learned about plants of this genus from French surgeon and naturalist Louis Deschamps when he was in Java between 1791 and 1794; but his notes and illustrations, seized by the British in 1803, were not available to western science until 1861. The first British person to see one was Joseph Arnold in 1818, in the Indonesia rainforest in Bengkulu, Sumatra, after a Malay servant working for him discovered a flower and pointed it out to him. The flower, and the genus, was later named after Stamford Raffles, the leader of the expedition and the founder of the British colony of Singapore. T ...

Brugmansia
''Brugmansia'' is a genus of seven species of flowering plants in the nightshade family Solanaceae. They are woody trees or shrubs, with pendulous flowers, and have no spines on their fruit. Their large, fragrant flowers give them their common name of angel's trumpets, a name sometimes used for the closely related genus ''Datura''. ''Brugmansia'' species are amongst the most toxic of ornamental plants, containing tropane alkaloids of the type also responsible for the toxicity and deliriant effects of both jimsonweed and the infamous deadly nightshade. All seven species are known only in cultivation or as escapees from cultivation, and no wild plants have ever been confirmed. They are therefore listed as Extinct in the Wild by the IUCN Red List, although they are popular ornamental plants and still exist wild outside their native range as introduced species. It is suspected that their extinction in the wild is due to the extinction of some animal which previously dispersed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barthélemy Charles Joseph Dumortier
Barthélemy Charles Joseph Dumortier (; 3 April 1797 in Tournai – 9 July 1878) was a Belgian who conducted a parallel career of botanist and Member of Parliament. Biography Barthélemy Dumortier was a son of the merchant and city councillor Barthélemy-François Dumortier and of Mariue-Jeanne Willaumez. He married Philippine Ruteau and they had a son, Barthélemy-Noël Dumortier (1830-1915). Barthélemy-Charles became politically active in the early eighteen twenties. In 1824 he founded the ''Courrier de l'Escaut'', a paper critical of the government. He adhered in 1830 to the Belgian revolution. In 1831 he became a member of the first elected parliament of the new kingdom, as the member for Tournai. He remained elected until 1847. He then switched seats, and was now elected for the city of Roulers and held this seat until his death. In 1872 he was awarded the honorary title of Minister of State. He also was awarded nobility with the title of earl. However, for unknown reaso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Datura
''Datura'' is a genus of nine species of highly poisonous, vespertine-flowering plants belonging to the nightshade family Solanaceae. They are commonly known as thornapples or jimsonweeds, but are also known as devil's trumpets (not to be confused with angel's trumpets, which are placed in the closely related genus '' Brugmansia''). Other English common names include moonflower, devil's weed, and hell's bells. All species of ''Datura'' are extremely poisonous and potentially psychoactive, especially their seeds and flowers, which can cause respiratory depression, arrhythmias, fever, delirium, hallucinations, anticholinergic syndrome, psychosis, and even death if taken internally. Due to their effects and symptoms, they have occasionally been used not only as poisons, but also as hallucinogens by various groups throughout history. Traditionally, psychoactive administration of ''Datura'' species has often been associated with witchcraft and sorcery or similar practices in m ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perianth
The perianth (perigonium, perigon or perigone in monocots) is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals) or tepals when called a perigone. The term ''perianth'' is derived from Greek περί (, "around") and άνθος (, "flower"), while ''perigonium'' is derived from περί () and γόνος (, "seed, sex organs"). In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure (or developing sporophyte). Flowering plants In flowering plants, the perianth may be described as being either dichlamydeous/heterochlamydeous in which the calyx and corolla are clearly separate, or homochlamydeous, in which they are indistinguishable (and the sepals and petals are collectively referred to as tepals). When the perianth is in two whorls, it is described as biseriate. While the ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
