Taxonomy Of The Euphorbiaceae
Here is a full taxonomy of the family Euphorbiaceae, according to the most recent molecular research. This complex family previously comprising 5 subfamilies: the Acalyphoideae, the Crotonoideae, the Euphorbioideae, the Phyllanthoideae and the Oldfieldioideae. The 3 first ones are uni-ovulate families while the 2 last one are bi-ovulate. Now the Euphorbiaceae has been split into 5 families: The 3 uni-ovulate subfamilies have become the Euphorbiaceae in the strict sense, with the tribe Galearieae in the Acalyphoideae forming the most of the family Pandaceae. Part of the bi-ovulate subfamily Phyllanthoideae has become the family Phyllanthaceae, with the tribe Drypeteae as family Putranjivaceae and the tribe Centroplaceae part of the Pandaceae. The other bi-ovulate subfamily Oldfieldioideae has become the Picrodendraceae. Subfamily Acalyphoideae Tribe Acalypheae There are 12 subtribes and 32 genera: :Subtribe Acalyphinae ::''Acalypha'' (also ''Acalyphes'', ''Acalyphopsis'', ''Ca ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
