Helwingia
The genus ''Helwingia'' consists of shrubs or rarely small trees native to eastern Asia, the Himalayas, and northern Indochina. It is the only genus in the family Helwingiaceae. Description The plants have alternate, evergreen or deciduous leaves and small inflorescences that are epiphyllous (growing from the leaf surface). During development, the flowers appear separate from the leaves,, eventually fusing with the leaf midrib. Flowers are small and yellow-green or purple, followed by red or black berries. Plants are dioecious. Epiphyllous inflorescences This trait is rather unusual among plants. This atypical floral position upon a leaf is believed to be an adaption to insect pollination. Pollinators which are too large to be supported by the floral pedicels, land on the leaf surface and can pollinate the flowers, which would not be able to support the pollinators on their own. Taxonomy The APG II classification (2003) places them in the order Aquifoliales, along with the holl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aquifoliales
The Aquifoliales are an order of flowering plants, including the Aquifoliaceae (holly) family, and also the Helwingiaceae (2-5 species of temperate Asian shrubs) and the Phyllonomaceae (4 species of Central American trees and shrubs). In 2001, the families Stemonuraceae and Cardiopteridaceae were added to this order. This circumscription of Aquifoliales was recognized by the Angiosperm Phylogeny Group when they published the APG II system in 2003. In the 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 ..., there is no Aquifoliales order: the Aquifoliaceae are placed within the order Celastrales and the others are in other families.

Phyllonomaceae
''Phyllonoma'' is a genus consisting of 4 species of trees and shrubs. ''Phyllonoma'' is the sole genus in the family Phyllonomaceae (an alternative name for the family is Dulongiaceae). ''Phyllonoma'' species are native to South and Central America (from Peru to Mexico). They can be recognized by the structure of their flowers (like the Helwingiaceae, they have epiphyllous inflorescences). The APG II classification (2003) places them in the order Aquifoliales, along with the hollies and Helwingiaceae. In the Cronquist classification (1981) this family does not exist: the genus ''Phyllonoma'' is included in the family Grossulariaceae ''Ribes'' () is a genus of about 200 known species of flowering plants, most of them native to the temperate regions of the Northern Hemisphere. The species may be known as various kinds of currants, such as redcurrants, blackcurrants, and whi ... (gooseberry or currant family). References External links Aquifoliales - Angiosperm Phyloge ...

Georg Andreas Helwing
Georg Andreas Helwing () (14 December 1666 – 3 January 1748) was a botanist and Lutheran pastor. Helwing was born in Angerburg (Węgorzewo) in Brandenburg-Prussia's Duchy of Prussia. He became a "remote member" of the Prussian Academy of Sciences on 31 August 1709. Helwing discovered and introduced several plants: '' Helwingia'' is named after him. He became known as the ''Tournefortius Borussicus'' and ''Prussian Plinius''. In 1999, the University of Warmia and Mazury in Olsztyn was founded with reference to him. It has been suggested that Georg Andreas Helwing was the inspiration for the character Abraham Van Helsing in Bram Stoker's famous novel ''Dracula ''Dracula'' is an 1897 Gothic fiction, Gothic horror fiction, horror novel by Irish author Bram Stoker.

Holly
''Ilex'' () or holly is a genus of over 570 species of flowering plants in the family Aquifoliaceae, and the only living genus in that family. ''Ilex'' has the most species of any woody dioecious angiosperm genus. The species are evergreen or deciduous trees, shrubs, and climbers from tropics to temperate zones worldwide. The type species is '' Ilex aquifolium'', the common European holly used in Christmas decorations and cards. Description The genus is widespread throughout the temperate and subtropical regions of the world. It includes species of trees, shrubs, and climbers, with evergreen or deciduous foliage and inconspicuous flowers. Its range was more extended in the Tertiary period and many species are adapted to laurel forest habitats. It occurs from sea level to more than with high mountain species. It is a genus of small, evergreen trees with smooth, glabrous, or pubescent branchlets. The plants are generally slow-growing with some species growing to tall. The ...

World Checklist Of Selected Plant Families
The World Checklist of Selected Plant Families (usually abbreviated to WCSP) was an "international collaborative programme that provides the latest peer reviewed and published opinions on the accepted scientific names and synonyms of selected plant families." Maintained by the Royal Botanic Gardens, Kew, it was available online, allowing searches for the names of families, genera and species, as well as the ability to create checklists. The project traced its history to work done in the 1990s by Kew researcher Rafaël Govaerts on a checklist of the genus ''Quercus''. Influenced by the Global Strategy for Plant Conservation, the project expanded. , 173 families of seed plants were included. Coverage of monocotyledon families was completed and other families were being added. There is a complementary project called the International Plant Names Index (IPNI), in which Kew is also involved. The IPNI aims to provide details of publication and does not aim to determine which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araliaceae
The Araliaceae are a family of flowering plants composed of about 43 genera and around 1500 species consisting of primarily woody plants and some herbaceous plants commonly called the ginseng family. The morphology of Araliaceae varies widely, but it is predominantly distinguishable based on its woody habit, tropical distribution, and the presence of simple umbels. There are numerous plants of economic importance. Some genera, such as ''Hedera'' (the ivies), '' Fatsia'' (Japanese aralias) and '' Heptapleurum'' (formerly ''Schefflera'', the umbrella trees), are used as ornamental foliage plants. The family also includes '' Panax ginseng'', the root of which is ginseng, used in traditional Chinese medicine. Overview The morphology of Araliaceae varies widely. Many studies have found that there is no unifying characteristic capable of classifying the family. In general, Araliaceae species have large, usually alternate leaves, often with aromatic ethereal oils, five-petaled fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornaceae
The Cornaceae are a cosmopolitan family of flowering plants in the order Cornales. The family contains approximately 85 species in two genera, '' Alangium'' and '' Cornus''. They are mostly trees and shrubs, which may be deciduous or evergreen, although a few species are perennial herbs. Members of the family usually have opposite or alternate simple leaves, four- or five-parted flowers clustered in inflorescences or pseudanthia, and drupaceous fruits.Kubitzki, K. (2004). Cornaceae. In ''The Families and Genera of Vascular Plants Volume 6: Flowering Plants: Dicotyledons: Celastrales, Oxidales, Rosales, Cornales, Ericales'' (Kubitzki, ed.). Springer-Verlag, New York. The family is primarily distributed in northern temperate regions and tropical Asia. In northern temperate areas, Cornaceae are well known from the dogwoods '' Cornus''. The systematics of Cornaceae has been remarkably unsettled and controversial, and many genera have been added to it and removed from it over time. ...

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 ...
