Trilliaceae
Trilliaceae was a family of flowering plants. The family has been recognised as distinct since 1846 when it was recognized; this tablfor a summarizes the placement of these taxa. The family has been recognized by taxonomists such as Takhtajan, Dahlgren, Thorne, and Watson & Dallwitz; other taxonomists have considered these plants to belong to the family Liliaceae. The APG IV system, of 2016 (unchanged from the APG system, of 1998), does not recognize such a family either and assigns the plants involved to family Melanthiaceae, tribe Parideae. One problem with this recognition is the lack of morphological synapomorphies for the family Melanthiaceae; this charprovides a summary of the characters in each of the major groups. Nevertheless, some taxonomists still recognize a separate family Trilliaceae. The most important genus in North America is ''Trillium'', and the taxonomy of that genus has always been controversial. To paraphrase what Steven Elliott wrote of the genus ''Trill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trillium
''Trillium'' (trillium, wakerobin, toadshade, tri flower, birthroot, birthwort, and sometimes "wood lily") is a genus of about fifty flowering plant species in the family Melanthiaceae. ''Trillium'' species are native to temperate regions of North America and Asia, with the greatest diversity of species found in the southern Appalachian Mountains in the southeastern United States. Description Plants of this genus are perennial herbs growing from rhizomes. There are three large leaf-like bracts arranged in a whorl about a scape that rises directly from the rhizome. There are no true aboveground leaves but sometimes there are scale-like leaves on the underground rhizome. The bracts are photosynthetic and are sometimes called leaves. The inflorescence is a single flower with three green or reddish sepals and three petals in shades of red, purple, pink, white, yellow, or green. At the center of the flower there are six stamens and three stigmas borne on a very short style, if any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanthiaceae
Melanthiaceae, also called the bunchflower family, is a family of flowering herbaceous perennial plants native to the Northern Hemisphere. Along with many other lilioid monocots, early authors considered members of this family to belong to the family Liliaceae, in part because both their sepals and petals closely resemble each other and are often large and showy like those of lilies, while some more recent taxonomists have placed them in a family Trilliaceae. The most authoritative modern treatment, however, the APG III system of 2009 (unchanged from the 2003 APG II system and the 1998 APG system), places the family in the order Liliales, in the clade monocots. Circumscribed in this way, the family includes up to 17 genera. Familiar members of the family include the genera ''Paris'' and ''Trillium''. Genera and species , the World Checklist of Selected Plant Families accepted 17 genera in the family.Search for "Melanthiaceae", They have been divided into five tribes. It h ...

Paris (plant)
''Paris'' is a genus of flowering plants described by Linnaeus in 1753. It is widespread across Europe and Asia, with a center of diversity in China. It consists of less than two dozen herbaceous plants: the best known species is ''Paris quadrifolia''. Some ''Paris'' species are used in traditional Chinese medicine for their analgesic and anticoagulant properties, most notably as an ingredient of Yunnan Baiyao. Intense ethnopharmaceutical interest has significantly reduced their numbers. These plants are closely related to ''Trillium'', with the distinction traditionally being that ''Trillium'' contains species which have trimerous (three-petaled) flowers, and ''Paris'' contains species which have 4- to 11-merous flowers. A recent analysis places the genera ''Daiswa'' and ''Kinugasa'' in ''Paris'', though the actual circumscription of the genus is debated.

Pseudotrillium
''Pseudotrillium'' is a monotypic genus of flowering plants in the family Melanthiaceae containing the single species ''Pseudotrillium rivale''. The genus was proposed in 2002 on the basis of morphology and molecular evidence that suggest the plant should no longer be included in genus ''Trillium''. ''Pseudotrillium rivale'', known by the common name brook wakerobin, is endemic to the Siskiyou Mountains of southern Oregon and northern California, usually on soils of ultramafic origin.. The Latin specific epithet ''rivale'' means “growing by streams”, with reference to a preferred habitat. Description ''Pseudotrillium rivale'' is a rhizomatous herbaceous perennial growing up to in height. The three bracts have generally lance-shaped blades up to long borne on petioles in length. The blades are glossy blue-green with silvery venations. Atop the whorl of bracts, on a pedicel high, is a single nodding non-fragrant flower with green sepals and pink-blushed white petals up to ...

Paris Quadrifolia
''Paris quadrifolia'', the herb Paris or true lover's knot, is a species of flowering plant in the family Melanthiaceae. It occurs in temperate and cool areas throughout Eurasia, from Spain to Yakutia, and from Iceland to Mongolia. It prefers calcareous soils and lives in damp and shady places, especially old established woods and stream banks. ''P. quadrifolia'' is in decline in Europe due to loss of habitat. In Iceland, for example, it is on the red list. Characteristics ''P. quadrifolia'' is a perennial herbaceous plant that is tall. It may have 3–8 leaves but typically there are four leaves arranged as opposing pairs. The flowers are wispy and inconspicuous. The plant flowers during the months of June and July. It has a solitary flower with four narrow greenish filiform (threadlike) petals, four green petaloid sepals, eight golden yellow stamens, and a round purple to red ovary. The flower is borne above a single whorl of four leaves. Each plant produces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kinugasa Japonica
is a Japanese species of plants in the genus ''Paris'' in the family Melanthiaceae.Ohwi, J. (1984). Flora of Japan (in English): 1-1067. Smithsonian Institution, Washington, D.C.. It is native to sub-alpine regions of Japan. A slow growing perennial, it flowers in July. The rare, showy white star-like flower is borne above a single whorl of about eight stem leaves. It prefers cool, humid, shady places. Genetics ''Paris japonica'' has the largest genome of any plant yet assayed, about 150 billion base pairs long. An octoploid and suspected allopolyploid hybrid of four species, it has 40 chromosomes. With 150 billion base pairs of DNA per cell (50 times larger than that of a human haploid genome), ''Paris japonica'' may possess the largest known genome of any living organism; the DNA from a single cell stretched out end-to-end would be longer than . The flower has 19 billion more base pairs than the previous record holder, the marbled lungfish, whose 130 billion base pairs weig ...

Stephen Elliott (botanist)
Stephen Elliott (November 11, 1771 – March 28, 1830) was an American legislator, banker, educator, and botanist who is today remembered for having written one of the most important works in American botany, ''A Sketch of the Botany of South-Carolina and Georgia''."Stephen Elliott (1771-1830) Papers" In: Archives of the Gray Herbarium. In: The Harvard University Herbaria. (see External links below). The plant genus '' Elliottia'' is named after him. Life Stephen Elliott was born in Beaufort, South Carolina, on November 11, 1771. He grew up there, then moved to New Haven, Connecticut, to attend Yale University. He graduated in 1791 as the valedictorian of his class. From Yale, he returned to South Carolina to work the plantation that he had inherited. He was elected to the legislature in South Carolina in 1793 or 1796 (sources disagree) and served until about 1800. He then left the legislature and devoted himself to the management of his plantation. He was re-elected to the legi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Synapomorphies
In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to have evolved in their most recent common ancestor. ) In cladistics, synapomorphy implies homology. Examples of apomorphy are the presence of erect gait, fur, the evolution of three middle ear bones, and mammary glands in mammals but not in other vertebrate animals such as amphibians or reptiles, which have retained their ancestral traits of a sprawling gait and lack of fur. Thus, these derived traits are also synapomorphies of mammals in general as they are not shared by other vertebrate animals. Etymology The word —coined by German entomologist Willi Hennig—is derived from the Ancient Greek words (''sún''), meaning "with, together"; (''apó''), meaning "away from"; and (''morphḗ''), meaning "shape, form".
