Didymocheton Mollis
''Didymocheton mollis'' is a species of flowering plant in the family Meliaceae. It is a tree native to Sulawesi, the Maluku Islands, New Guinea, and the Bismarck Archipelago. It is most closely related to '' Didymocheton mollissimus'' of Malesia and mainland Southeast Asia, '' D. alliaceus'' of the Solomon Islands and western Pacific Islands, and '' D. muelleri'' of northeastern Australia. Taxonomy The species was first described as ''Dysoxylum molle'' by Friedrich Anton Wilhelm Miquel in 1868, from a holotype collected in southwestern New Guinea. In 1994 David Mabberley reclassified it as ''Dysoxylum mollissimum'' subsp. ''molle'', which included the populations in Sulawesi, Maluku, New Guinea, and the Bismarck Archipelago, along with Australian populations previously classified as ''Dysoxylum muelleri''. A 2021 study by Holzmeyer, Hauenschild, Mabberley, ''et al.'' concluded that ''Dysoxylum'' was polyphyletic, and that the Australian population constituted a distinct species ...

Friedrich Anton Wilhelm Miquel
Friedrich Anton Wilhelm Miquel (24 October 1811 – 23 January 1871) was a Dutch botanist, whose main focus of study was on the flora of the Dutch East Indies. Early life Miquel was born in Neuenhaus and studied medicine at the University of Groningen, where, in 1833, he received his doctorate. After starting work as a doctor at the Buitengasthuis Hospital in Amsterdam, in 1835, he taught medicine at the clinical school in Rotterdam. In 1838 he became correspondent of the Royal Institute, which later became the Royal Netherlands Academy of Arts and Sciences, and in 1846 he became member. He was professor of botany at the University of Amsterdam (1846–1859) and Utrecht University (1859–1871). He directed the Rijksherbarium (National Herbarium) at Leiden from 1862. In 1866, he was elected a foreign member of the Royal Swedish Academy of Sciences. Research Miquel did research on the taxonomy of plants. He was interested in the flora of the Dutch Empire, specifically the Dutch E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Sulawesi
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''. 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 Thurman ...

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index The Australian Plant Name Index (APNI) is an online database of all published names of Australian vascular plants. It covers all names, whether current names, synonyms or invalid names. It includes bibliographic and typification details, informati ... * Convention on Biological Diversity * W ...

Didymocheton
''Dysoxylum'' is a flowering plant genus of trees and shrubs from the mahogany family, Meliaceae. Botanical science has recorded about eighty species in this genus, growing widely across the regions of Malesia, the western Pacific ocean, Australia and south & southeastern Asia; centred on the tropics between the Pacific and Indian Oceans. They grow naturally in New Guinea, eastern and northern Australia, New Caledonia, Fiji, SE Asia, southern China, the Indian subcontinent, the Philippines, Taiwan, and in the western Pacific Ocean their most easterly occurrences, in the Caroline Islands, New Zealand and Niue. The etymology of its name ''Dysoxylum'' derives from the Greek word ‘''Dys''’ meaning "bad" referring to "ill-smelling" and ‘''Xylon''’ meaning "wood". Distribution New Guinea has records of twenty eight species growing naturally, sixteen of them endemic. New Caledonia has recorded nine, eight of them endemic. Fiji has recorded nine, seven of them endemic. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with syste ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...

Didymocheton Muelleri
''Didymocheton muelleri'', the red bean or Miva mahogany, is a rainforest tree in the family Meliaceae. It occurs in tropical, sub-tropical and littoral rainforests in eastern Australia, from the Bellinger River in New South Wales in the south, to the wet tropics of north-eastern Queensland. A signposted red bean tree may be seen near the car park of Victoria Park Nature Reserve in north-eastern New South Wales. Description It is a large and impressive tree, up to tall and a trunk diameter of . It is usually buttressed or flanged at the base, and the trunk is scaly and rough, grey or brown in colour. Freshly cut bark has an onion type scent. Leaves Leaflets are usually opposite on the stem, without serrations, and distinctly asymmetrical at the leaf base. Leaflets are long and wide, and are mid green above, paler below, and sometimes softly hairy under the leaf. ''True leaves'' are long, pinnate. Leaf stem swollen where joining the larger branch. Leaf venation is evident a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. They include all forbs (flowering plants without a woody stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. The term "angiosperm" is derived from the Greek words ἀγγεῖον / ('container, vessel') and σπέρμα / ('seed'), meaning that the seeds are enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Angiosperms are distinguished from the other seed-producing plants, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the common ance ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
