Icacinales
Icacinales is an order of flowering plants. The order did not exist in the 2009 APG III system, and was added in the 2016 APG IV system, including two families, Icacinaceae The Icacinaceae, also called the white pear family, are a family (biology), family of flowering plants,"Icacinaceae" At: Angiosperm Phylogeny Website At: Missouri Botanical Garden Website (see ''External links'' below). consisting of trees, shrub ... and Oncothecaceae, which were both unplaced families in APG III.

APG IV System
The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG). It was published in 2016, seven years after its predecessor the APG III system was published in 2009, and 18 years after the first APG system was published in 1998. In 2009, a linear arrangement of the system was published separately; the APG IV paper includes such an arrangement, cross-referenced to the 2009 one. Compared to the APG III system, the APG IV system recognizes five new orders ( Boraginales, Dilleniales, Icacinales, Metteniusales and Vahliales), along with some new families, making a total of 64 angiosperm orders and 416 families. In general, the authors describe their philosophy as "conservative", based on making changes from APG III only where "a well-supported need" has been demonstrated. This has sometimes resulted in placements th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Asterids
Asterids are a large clade (monophyly, monophyletic group) of flowering plants, composed of 17 Order_(biology), orders and more than 80,000 species, about a third of the total flowering plant species. The asterids are divided into the unranked clades lamiids (8 orders) and campanulids (7 orders), and the single orders Cornales and Ericales. Well-known asterids include Cornus, dogwoods and hydrangeas (order Cornales), Camellia sinensis, tea, blueberry, blueberries, Cranberry, cranberries, kiwifruit, Brazil nuts, Argania, argan, sapote, and azaleas (order Ericales), common sunflower, sunflowers, lettuce, Bellis perennis, common daisy, yacon, carrots, celery, parsley, parsnips, Panax ginseng, ginseng, Hedera, ivies, holly, honeysuckle, Sambucus, elder, and Valerian (herb), valerian (clade campanulids), borage, Myosotis, forget-me-nots, Symphytum, comfrey, Coffea, coffee, Plumeria, frangipani, Gentiana, gentian, Cerbera odollam, pong-pong, Nerium oleander, oleander, Vinca, periwinkle, ...

Icacinaceae
The Icacinaceae, also called the white pear family, are a family (biology), family of flowering plants,"Icacinaceae" At: Angiosperm Phylogeny Website At: Missouri Botanical Garden Website (see ''External links'' below). consisting of trees, shrubs, and lianas, primarily of the tropics. The family was traditionally Circumscription (taxonomy), circumscribed quite broadly, with around 55 genera totalling over 400 species. In 2001, though, this circumscription was found to be polyphyletic, and the family was split into four families in three different Order (biology), orders: Icacinaceae ''sensu stricto'' (then unplaced at order rank), Pennantiaceae (Apiales), Stemonuraceae (Aquifoliales) and Cardiopteridaceae (also Aquifoliales). Other genera have later been moved to Metteniusaceae (Metteniusales),Stull, G. W., R. Duno de Stefano, D. E. Soltis, and P. S. Soltis (2015).

Oncothecaceae
''Oncotheca'' is a genus of tree endemic to New Caledonia. There are two species, ''Oncotheca balansae'' and ''Oncotheca humboldtiana''. ''Oncotheca'' is the sole genus of the Oncothecaceae, which is one of three families of flowering plants endemic to New Caledonia. Its placement has been enigmatic for a long time, but a recent phylogenetic analysisStull, G. W., R. Duno de Stefano, D. E. Soltis, and P. S. Soltis. (2015).

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...

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 ...

Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...
