Dilleniales
The Dilleniales are an order of flowering plants, potentially containing one family, Dilleniaceae. The APG III system of 2009, like the earlier APG II system of 2003, left the Dilleniaceae unplaced as to order, while noting that the name Dilleniales was available. Stevens at the Angiosperm Phylogeny Website has subsequently placed Dilleniaceae in the order Dilleniales. The Cronquist system, of 1981, recognized such an order and placed it in subclass Dilleniidae. It used the following circumscription: *order Dilleniales *: family Dilleniaceae The Takhtajan system of 1969 had the families Dilleniaceae and Crossosomataceae in the order. The APG III system assigned the second of these families, the Paeoniaceae, to the order Saxifragales Saxifragales is an order (biology), order of flowering plants in the Superrosids, superrosid clade of the eudicots. It contains 15 Families (biology), families and around 100 genera, with nearly 2,500 species. Well-known and economica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Core Eudicots
The eudicots or eudicotyledons are flowering plants that have two seed leaves (cotyledons) upon germination. The term derives from ''dicotyledon'' (etymologically, ''eu'' = true; ''di'' = two; ''cotyledon'' = seed leaf). Historically, authors have used the terms tricolpates or non-magnoliid dicots. The current botanical terms were introduced in 1991, by evolutionary botanist James A. Doyle and paleobotanist Carol L. Hotton, to emphasize the later evolutionary divergence of tricolpate dicots from earlier, less specialized, dicots. Scores of familiar plants are eudicots, including many commonly cultivated and edible plants, numerous trees, tropicals and ornamentals. Among the most well-known eudicot genera are those of the sunflower (''Helianthus''), dandelion (''Taraxacum''), forget-me-not ('' Myosotis''), cabbage ('' Brassica''), apple (''Malus''), buttercup ('' Ranunculus''), maple ('' Acer'') and macadamia (''Macadamia''). Most leafy, mid-latitude trees are also classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dilleniaceae
Dilleniaceae is a family of flowering plants with 11 genera and about 430 known species. It is known to gardeners for the genus '' Hibbertia'', which contains many commercially valuable garden species. Description and distribution The family is found in the tropics and subtropics plus all of Australia. Most of the members in it are woody plants - lianas or trees such as '' Dillenia'' - but herbaceous species such as ''Hibbertia'' are also present in Dilleniaceae. The leaves of the plants in the family are wide and well-developed, but in certain species of '' Hibbertia'' they are strongly modified. The flowers are mainly showy and colorful with visible reproductive components. Buzz pollination is common in the group. Fruits of some species, such as ''Dillenia indica'' (elephant apple), are edible. Taxonomy and phylogeny left, '' Dillenia suffruticosa'' The position of the family in the phylogenetic tree and its classification among the other eudicots is uncertain. Some studies ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, 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 commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cronquist System
The Cronquist system is a list of systems of plant taxonomy, taxonomic classification system of angiosperms, 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, 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 a ...

Dilleniidae
Dilleniidae 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 Dilleniaceae. A well-known system that uses this name is the Cronquist system, and in the original 1981 version of the system the circumscription was: * subclass Dilleniidae *: order Dilleniales *: order Theales *: order Malvales *: order Lecythidales *: order Nepenthales *: order Violales *: order Salicales *: order Capparales *: order Batales *: order Ericales *: order Diapensiales *: order Ebenales *: order Primulales Recent molecular systematic studies have shown that this group is polyphyletic. The APG II system does not use formal botanical names above the rank of order but assigns the plants involved to various orders in the asterids and rosids clades.

Saxifragales
Saxifragales is an order (biology), order of flowering plants in the Superrosids, superrosid clade of the eudicots. It contains 15 Families (biology), families and around 100 genera, with nearly 2,500 species. Well-known and economically important members of this order include Saxifraga, saxifrages (after whom the order is named), blackcurrants, redcurrants, Gooseberry, gooseberries, Peony, peonies, liquidambars, witch-hazel, Parrotia persica, Persian ironwood, Cercidiphyllum, katsura, Crassula ovata, jade plant, Sempervivum, houseleeks, and Myriophyllum, water milfoil. Of the 15 families, many are small, with eight of them being Monotypic taxon, monotypic (having only a single genus). The largest family is the Crassulaceae (stonecrops), a diverse group of mostly Succulent plant, succulent plants, with about 35 genera. Saxifragales are found worldwide, primarily in Temperate climate, temperate to Subtropics, subtropical zones, rarely being encountered growing wild in the tropi ...

Paleogene
The Paleogene Period ( ; also spelled Palaeogene or Palæogene) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period Ma (million years ago) to the beginning of the Neogene Period Ma. It is the first period of the Cenozoic Era, the tenth period of the Phanerozoic and is divided into the Paleocene, Eocene, and Oligocene epochs. The earlier term Tertiary Period was used to define the time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognized as a formal stratigraphic term, "Tertiary" still sometimes remains in informal use. Paleogene is often abbreviated "Pg", although the United States Geological Survey uses the abbreviation "" for the Paleogene on the Survey's geologic maps. Much of the world's modern vertebrate diversity originated in a rapid surge of diversification in the early Paleogene, as survivors of the Cretaceous–Paleogene extinction event took advantage of empty ecolo ...

Hibbertia Stellaris
''Hibbertia stellaris'', commonly known as star guinea flower or orange stars, is a brilliantly orange flowering ground cover from the South Western Australian botanical province. It naturally grows in swamps; despite this, it is extremely sensitive to ''phytophthora'' and needs to be grown in well-drained soil in cultivation. Description ''Hibbertia stellaris'' grows as a small shrub 30–70 cm high and 30–60 cm across. The stems are often red-tinged. The linear to narrow-spathulate (spoonshaped) leaves measure 1.5-2.5 cm long and 0.5-2.5 mm across. The orange flowers appear from August to February, with populations from the more northern parts of its range having more yellowish flowers. Taxonomy Austrian botanist Stephan Endlicher described ''Hibbertia stellaris'' in his 1837 work ''Enumeratio plantarum quas in Novae Hollandiae ora austro-occidentali ad fluvium Cygnorum et in sinu Regis Georgii collegit Carolus Liber Baro de Hügel'', from a specimen col ...

Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and 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. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
APG III System
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system. Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society: * The first, by Chase & Reveal, was a formal phylogenetic classification of all land plants (embryophytes), compatible with the APG III classification. As the APG have chosen to eschew ranks above order, this paper was meant to fit the system into the existing Linnaean hierarchy for those that prefer such a classification. The result was that all land plants were placed in the class Equisetopsida, which was then divided into 16 subclasses and a multitude of superorders. * The second, by Haston ''et al.'', was a linear sequence of families fol ...
