Berberidopsidaceae is the botanical name for a family of flowering plants. Such a family has been recognized by only a few taxonomists: the plants involved have often been treated as belonging to family Flacourtiaceae. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms (as opposed to folk taxonomy). ...

In the APG and APG II system for classification of angiosperms, the names eudicots or tricolpates are applied to a clade, a monophyletic group. ... A botanical name is a formal name conforming to the ICBN. As with its zoological and bacterial equivalents it may also be called a scientific name. Botanical names may be in one part (genus and above), two parts (species) or three parts (below the rank of species). ... In biological classification, family (Latin: familia, plural familiae) is 1) a rank or 2) a taxon in that rank. ... Classes Magnoliopsida - Dicots Liliopsida - Monocots The flowering plants (also angiosperms or Magnoliophyta) are one of the major groups of modern plants, comprising those that produce seeds in specialized reproductive organs called flowers, where the ovulary or carpel is enclosed. ...

The APG II system, of 2003 (unchanged from the APG system, of 1998), does recognize this family, unplaced as to order and merely assigned to the clade core eudicots. The family consists of one or two genera, Berberidopsis, with two species and Streptothamnus, with a single species. A modern system of plant taxonomy, the APG II system of plant classification was published in 2003 by the Angiosperm Phylogeny Group, APG, in Angiosperm Phylogeny Group (2003). ... A modern system of plant taxonomy, the APG system of plant classification was published in 1998 by the Angiosperm Phylogeny Group. ... In the APG and APG II system for classification of angiosperms, the names eudicots or tricolpates are applied to a clade, a monophyletic group. ... Species Berberidopsis beckleri - montane tape vine Berberidopsis corallina - coral plant Berberidopsis is a genus of flowering plants and the sole reason anarchy exists. ...


However, APG II mentions the possibility of recognizing an order Berberidopsidales, which would comprise the two families Aextoxicaceae and Berberidopsidaceae. Although APG II decides not to do so, the AP-Website does assume such an order, suggesting that this may be taken up in APG III. Families Berberidopsidaceae Aextoxicaceae The Berberidopsidales are a tiny order of dicotyledons, comprising the families Berberidopsidaceae and Aextoxicaceae. ... species Aextoxicon punctatum is a tree native to southern Chile, commonly known as the Olivillo or Aceitunillo. ...

Berberidopsidales (1278 words)
Berberidopsidaceae are woody scramblers that can be recognised by their exstipulate, sometimes spiny-toothed leaf blades with palmate venation; the veins run straight into the spines, when present.
In Streptothamnus the disc is absent, or perhaps it is to be found between the stamens and the gynoecium.
Berberidopsidaceae were included in Flacourtiaceae by Cronquist (1981) and in Violales by Takhtajan (1997).
Core Eudicots (4199 words)
Recent studies identified Gunnerales as the sister to all other core eudicots (D. Soltis et al., 2003; Hilu et al., 2003); however, relationships among the remaining lineages are largely unresolved.
Like Gunnerales, "Berberidopsidales" comprise two small and morphologically disparate families: Berberidopsidaceae (Berberidopsis and Streptothamnus; the latter is sometimes included in Berberidopsis) and Aextoxicaceae (Aextoxicon, one species).
Although this clade has not been recognized at the ordinal level by APG (hence the quotation marks), it is strongly supported by molecular data and is isolated from all other clades.
