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, there is no Aquifoliales order: the Aquifoliaceae are placed within the order Celastrales The Celastrales are an order of flowering plants found throughout the tropics and subtropics, with only a few species extending far into the temperate regions.

Cardiopteridaceae
Cardiopteridaceae is a eudicot family of flowering plants. It consists of about 43 species of trees, shrubs, and woody vines, mostly of the tropics, but with a few in temperate regions.Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. (2007). . It contains six genera, the largest of which is '' Citronella'', with 21 species. The other genera are much smaller.David J. Mabberley. 2008. ''Mabberley's Plant-Book'' third edition (2008).

Helwingiaceae
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, but eventually fuse 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 strange floral position upon a leaf is believed to be an adaption to insect pollination. Pollinators, which are too large for the flowers, land on the leaf surfaces and can pollinate the flowers, which would not be able to support the pollinators themselves. Taxonomy The APG II classification (2003) places them in the order Aquifoliales, along with the hollies and Phyllonomaceae, ...

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 Ilex, hollies and Helwingiaceae 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 leave .... In the Cronquist system, Cronquist classification (1981) this family does not exist: the genus ''Phyllonoma'' is included in the family Grossulariaceae (gooseberry or currant family).

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 ...

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. History APG II was published as: *Angiosperm Phylogeny Group (2003). "An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG II".

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Celastrales
The Celastrales are an order of flowering plants found throughout the tropics and subtropics, with only a few species extending far into the temperate regions. The 1200"Lepidobotryaceae", "Parnassiaceae", and "Celastraceae" In: Klaus Kubitzki (ed.). ''The Families and Genera of Vascular Plants'' vol. VI. Springer-Verlag: Berlin;Heidelberg, Germany. (2004). (vol. VI). to 1350Peter F. Stevens (2001 onwards)CelastralesAtaMissouri Botanical Garden/ref> species are in about 100 genera. All but seven of these genera are in the large family Celastraceae. Until recently, the composition of the order and its division into families varied greatly from one author to another. Description The Celastrales are a diverse order that has no conspicuous distinguishing characteristic, so is consequently hard to recognize. The flowers are usually small with a conspicuous nectary disk. The stipules are small or rarely absent. The micropyle has two openings and is therefore called a bistomal micro ...

Cronquist System
The Cronquist system is a taxonomic classification system of 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). 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 and 19 orders and 65 families in class Liliopsida. ''The Evo ...

Angiosperm Phylogeny Group
The Angiosperm Phylogeny Group (APG) is an informal international group of systematic botanists who collaborate to establish a consensus on the taxonomy of flowering plants (angiosperms) that reflects new knowledge about plant relationships discovered through phylogenetic studies. , four incremental versions of a classification system have resulted from this collaboration, published in 1998, 2003, 2009 and 2016. An important motivation for the group was what they considered deficiencies in prior angiosperm classifications since they were not based on monophyletic groups (i.e., groups that include all the descendants of a common ancestor). APG publications are increasingly influential, with a number of major herbaria changing the arrangement of their collections to match the latest APG system. Angiosperm classification and the APG In the past, classification systems were typically produced by an individual botanist or by a small group. The result was a large number of systems ( ...

Yerba Mate
Yerba mate or yerba-maté (''Ilex paraguariensis''; from Spanish ; pt, erva-mate, or ; gn, ka'a, ) is a plant species of the holly genus ''Ilex'' native to South America. It was named by the French botanist Augustin Saint-Hilaire. The leaves of the plant can be steeped in hot water to make a beverage known as ''mate''. Brewed cold, it is used to make ''tereré''. Both the plant and the beverage contain caffeine. The indigenous Guaraní and some Tupí communities (whose territory covered present-day Paraguay) first cultivated and consumed yerba mate prior to European colonization of the Americas. Its consumption was exclusive to the natives of only two regions of the territory that today is Paraguay, more specifically the departments of Amambay and Alto Paraná. After the Jesuits discovered its commercialization potential, yerba mate became widespread throughout the province and even elsewhere in the Spanish Crown. Mate is traditionally consumed in central and southern regi ...
