Rafflesiales
Rafflesiales is a botanical name of an order of flowering plants. The name was first published by Oliver in 1895. The Cronquist system used this name for an order placed in subclass Rosidae with the following circumscription (1981) : * order Rafflesiales *: family Hydnoraceae *: family Mitrastemonaceae *: family Rafflesiaceae The APG II system regards Rafflesiaceae as an unplaced family of three genera. Also unplaced is the genus ''Mitrastema''. However, APG II does have a placement for family Hydnoraceae, in the order Piperales. According to the AP-Website recent research places Rafflesiaceae in order Malpighiales The Malpighiales comprise one of the largest orders of flowering plants, containing about 36 families and more than species, about 7.8% of the eudicots. The order is very diverse, containing plants as different as the willow, violet, poinsett .... Historically recognized angiosperm orders {{angiosperm-stub ...

Rosidae
Under the International Code of Nomenclature for algae, fungi, and plants (ICN), Rosidae is a botanical name at the rank of subclass. Circumscription of the subclass will vary with the taxonomic system being used; the only requirement being that it includes the family Rosaceae. Under Phylocode, Rosidae is a clade defined as the most inclusive crown clade containing ''Rosa cinnamomea'',''sensu'' L. 1753 ''non'' L. 1759 but not '' Berberidopsis corallina'' nor ''Dillenia indica'' nor ''Gunnera manicata'' nor '' Helianthus annuus'' nor ''Saxifraga mertensiana'' nor '' Stellaria media'' nor ''Viscum album''. A well-known example of Rosidae as governed by the ICN was in the Cronquist system. In the 1981, original, version of that system, the circumscription was as follows. Arthur John Cronquist. 1981. ''An Integrated System of Classification of Flowering Plants''. Columbia University Press: New York, NY, USA. * subclass Rosidae The Phylocode definition includes Crossosomatales, G ...

Mitrastemonaceae
''Mitrastemon'' is a genus of two widely disjunct species of parasitic plants. It is the only genus within the family Mitrastemonaceae. ''Mitrastemon'' species are root endoparasites, which grow on Fagaceae. It is also a non-photosynthetic plant that parasitizes other plants such as ''Castanopsis sieboldii''. The parasitic plant was first discovered by botanist Eizi Matuda during an expedition to Mt. Ovand in the state of Chiapas, Mexico (Matuda, 1947). The different species were originally named by a friend of Matuda, Yamamoto in 1925–1926. ''Mitrastemon yamamotoi'' is a protandrous plant. Its flowers go through a male phase before transforming into their final female form. The flowers of ''M. yamamotoi'' attract a variety of insects ranging from wasps to flies and beetles. Among these, beetles are the best pollinators for this plant since their visit to the flower would pick up a large amount of pollen and they would pollinate from each of the flowers that they had already v ...

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 are gener ...

Rafflesia Kerrii Khao Sok
''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. The f ...

Cronquist System
The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of Flowering Plants'' (1968; 2nd edition, 1988) and ''An Integrated System of Classification of Flowering Plants'' (1981) (''see'' Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida ( dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. While the scheme was widely used, in either the original form or in adapted versions, many botanists now use the Angiosperm Phylogeny Group classification for the orders and families of flowering plants, first developed in 1998. The system as laid out in Cronquist's ''An Integrated System of Classification of Flowering Plants'' (1981) counts 64 orders and 321 families in class Magnoliopsida and 19 orders and 65 families in class Liliopsida.

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds 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 (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daniel Oliver (botanist)
Daniel Oliver, FRS (6 February 1830, Newcastle upon Tyne – 21 December 1916) was an English botanist. He was Librarian of the Herbarium, Royal Botanic Gardens, Kew from 1860–1890 and Keeper there from 1864–1890, and Professor of Botany at University College, London from 1861–1888. In 1864, while at UCL, he published ''Lessons in Elementary Biology'', based upon material left in manuscript by John Stevens Henslow, and illustrated by Henslow's daughter, Anne Henslow Barnard of Cheltenham. With a second edition in 1869 and a third in 1878 this book was reprinted until at least 1891. Oliver regarded this book as suitable for use in schools and for young people remote from the classroom and laboratory. He was elected a member of the Linnean Society, awarded their Gold Medal in 1893, and awarded a Royal Medal by the Royal Society in 1884. He married in 1861 and was the father of two daughters and a son, Francis Wall Oliver. In 1895, botanist Tiegh published '' Oliverella'', a ...

Hydnoraceae
Hydnoroideae is a subfamily of parasitic flowering plants in the order Piperales. Traditionally, and as recently as the APG III system it given family rank under the name Hydnoraceae. It is now submerged in the Aristolochiaceae. It contains two genera, ''Hydnora'' and ''Prosopanche'': * ''Prosopanche'' is native to Central and South America ; * ''Hydnora'' can be found in semi-arid to desert regions of Africa, the Arabian Peninsula, and Madagascar. Members of this subfamily have been described as the strangest plants in the world. Description The most striking aspect of the Hydnoroideae is probably the complete absence of leaves (not even in modified forms such as scales). Some species are mildly thermogenic (capable of producing heat), presumably as a means of dispersing their scent.
