Austrobaileyales
Austrobaileyales is an order of flowering plants consisting of about 100 species of woody plants growing as trees, shrubs and lianas. The best-known species is ''Illicium verum'', commonly known as star anise. The order belongs to the group of basal angiosperms, the ANA grade (Amborellales, Nymphaeales, and Austrobaileyales), which diverged earlier from the remaining flowering plants. Austrobaileyales is sister to all remaining extant angiosperms outside the ANA grade.Insights into the dynamics of genome size and chromosome evolution in the early diverging angiosperm lineage Nymphaeales (water lilies), Jaume Pellicer, Laura J Kelly, Carlos Magdalena, Ilia Leitch, 2013, Genome, 10.1139/gen-2013-0039 The order includes just three families of flowering plants, the Austrobaileyaceae, a monotypic family containing the sole genus, ''Austrobaileya scandens'', a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing essential oils, and the Trimeniaceae, essentia ...

Basal Angiosperms
The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of '' Amborella'' (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody aromatic plants including star anise). ''ANITA'' stands for ''Amborella'', ''N''ymphaeales, ''I'' lliciales, ''T''rimeniaceae, and '' Austrobaileya''. Some authors have shortened this to ''ANA''-grade for the three orders, ''A''mborellales, ''N''ymphaeales, and ''A''ustrobaileyales, since the order Iliciales was reduced to the family Illiciaceae and placed, along with the family Trimeniaceae, within the Austrobaileyales. The basal angiosperms are only a few hundred species, compared with hundreds of thousands of species of eudicots, monocots, and magnoliids. They diverged from the ancestral angiosperm lineage before ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trimeniaceae
Trimeniaceae is a family of flowering plants recognized by most taxonomists, at least for the past several decades. It is a small family of one genus, '' Trimenia'', with eight known species (Christenhusz & Byng 2016) of woody plants, bearing essential oils. The family is subtropical to tropical and found in Southeast Asia, eastern Australia and on several Pacific Islands. Taxonomy APG IV The APG IV system, of 2016, recognizes this family and places it in order Austrobaileyales, an order which is accepted as being among the most basal lineages in the clade angiosperms. APG III The APG III system, of 2009, also recognizes such a family and places it in order Austrobaileyales, an order which is accepted as being among the most basal lineages in the clade angiosperms. APG II The APG II system, of 2003, also recognizes such a family and places it in order Austrobaileyales, an order which is accepted as being among the most basal lineages in the clade angiosperms.

Austrobaileyaceae
''Austrobaileya'' is the sole genus consisting of a single species that constitutes the entire flowering plant family Austrobaileyaceae. The species ''Austrobaileya scandens'' grows naturally only in the Wet Tropics rainforests of northeastern Queensland, Australia. The name ''A. maculata'' is recognized as a synonym of ''A. scandens''. ''Austrobaileya'' plants grow as woody lianas or vines. Their main growing stems loosely twine, with straight, extending, leafy branches. The leaves are leathery, veined and simple. The leaves produce essential oils in spherical ethereal oil cells. Their foliage is damaged by oxidation in direct sunlight, so it tends to grow beneath the rainforest canopy, in low-sunlight and very humid conditions. Like many other flowering plants growing in the understory of tropical rainforest, it does not have palisade mesophyll tissue or low leaf photosynthetic rates. It relies strongly on vegetative reproduction for continuation of the species. ''Aus ... [...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. 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] |
Schisandraceae
Schisandraceae is a family of flowering plants with 3 known genera and a total of 92 known species. Such a family has been recognized by most taxonomists, at least for the past several decades. Before that, the plants concerned were assigned to family Magnoliaceae and Illiciaceae. The APG IV and APG III systems of taxonomy recognize this family and place it on the order Austrobaileyales. The APG II system, of 2003, also recognizes such a family. It places the family in order Austrobaileyales, which in turn is accepted as being among the most basic lineages in the clade angiosperms. APG II assumes this to be a family of three genera, the Schisandraceae ''sensu lato''. This family consists of woody plants, containing essential oils. However, APG II does allow the option of segregating the genus ''Illicium'' as the family Illiciaceae. This leaves only two genera in the family Schisandraceae ''sensu stricto'', consisting of ''Schisandra'' and ''Kadsura'', totalling several dozen s ...

APG II System
The APG II system (Angiosperm Phylogeny Group II system) of plant classification is the second, now obsolete, version of a modern, mostly molecular-based, system of plant taxonomy that was published in April 2003 by the Angiosperm Phylogeny Group.Angiosperm Phylogeny Group (2003)An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG II.''Botanical Journal of the Linnean Society'' 141(4): 399-436. doi: 10.1046/j.1095-8339.2003.t01-1-00158.x It was a revision of the first APG system, published in 1998, and was superseded in 2009 by a further revision, the APG III system.

Nymphaeales
The Nymphaeales are an order (biology), order of flowering plants, consisting of three Family (biology), families of aquatic plants, the Hydatellaceae, the Cabombaceae, and the Nymphaeaceae (water lilies). It is one of the three orders of basal angiosperms, an Basal (phylogenetics), early-diverging Evolutionary grade, grade of flowering plants. At least 10 Plant morphology, morphological Phenotypic trait, characters unite the Nymphaeales.Peter F. Stevens. 2001 onwards. Angiosperm Phylogeny Website At: Missouri Botanical Garden Website. (see ''External links'' below). One of the traits is the absence of a vascular cambium, which is required to produce both xylem (wood) and phloem, which therefore are missing. Molecular phylogenetics, Molecular synapomorphies are also known. The Plant List, created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden recognizes about 70 species in 11 genera within the order,The Plant List (website). 2010.

Reveal System
A 20th-century system of plant taxonomy, the Reveal system (see also the Thorne & Reveal system) of plant classification was drawn up by the American botanist James Reveal (1941-2015). The system was published online in 1997 in ten parts as lecture notes comparing the major systems in use at that time. Subsequently, Reveal became an author with the consensus Angiosperm Phylogeny Group (APG) on the APG II 2003 and APG III 2009 processes. Although this largely supplanted the earlier and competing systems, he collaborated with Robert Thorne on his system (2007), and subsequently continued to develop his own system. 1997 system * division Magnoliophyta angiosperms*: class Magnoliopsida *:: subclass Magnoliidae *: class Piperopsida *:: subclass Piperidae *:: subclass Nymphaeidae *:: subclass Nelumbonidae *: class Liliopsida monocots*:: subclass Triurididae *:: subclass Aridae *:: subclass Liliidae *:: subclass Arecidae *:: subclass Commelinidae *:: subclass Zingiberida ...

Illiciaceae
Illiciaceae A.C.Sm. was a family of flowering plants recognized in a number of systems of plant taxonomy. The Illiciaceae is not recognized as a distinct family by the APG III system of plant taxonomy, the most well accepted system in use today. The APG II system treated Illiciaceae as a family that may either be treated as part of another family, the Schisandraceae or allows for the optional segregation of the Illiciaceae from the Schisandraceae. The Illiciaceae as an optional segregate family then has the traditional circumscription of other taxonomic systems, consisting of a single genus, ''Illicium''. The updated APG III system of 2009 does not recognize this family and includes ''Illicium'' in the Schisandraceae. Description The family consists of shrubs or small trees usually with volatile aromatic compounds. The leaves are evergreen, simple, alternate, spiral (sometimes crowded towards the tips of the twigs), leathery, petiolate, pinnately veined, non-sheathing, gland ...

Vine
A vine (Latin ''vīnea'' "grapevine", "vineyard", from ''vīnum'' "wine") is any plant with a growth habit of trailing or scandent (that is, climbing) stems, lianas or runners. The word ''vine'' can also refer to such stems or runners themselves, for instance, when used in wicker work.Jackson; Benjamin; Daydon (1928). ''A Glossary of Botanic Terms with their Derivation and Accent'', 4th ed. London: Gerald Duckworth & Co. In parts of the world, including the British Isles, the term "vine" usually applies exclusively to grapevines (''Vitis''), while the term "climber" is used for all climbing plants. Growth forms Certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, but will become vines when support is available. A vine displays a growth form based on very long stems. This has two purposes. A vine may use rock exposures, other plants, or other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
