Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. ... For other uses, see Plant (disambiguation). ... The name magnoliids (plural, not capitalized) or magnoliid complex is used by the APG II system for a clade within the angiosperms. ... Arthur J. Cronquist (1919–1992) was a North American botanist, a specialist on Compositae, most famous for the Cronquist system, laid down in An Integrated System of Classification of Flowering Plants (1981) and The Evolution and Classification of Flowering Plants (1988). ...
Canellales is the botanical name for an order of flowering plants. It is only rarely recognized by systems of plant classification. 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). ... 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. ... This list of systems of plant taxonomy presents “taxonomic systems†used in plant classification. ...
The APG II system, of 2003, does accept this order and places it in the clade magnoliids, using this circumscription: 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). ... The name magnoliids (plural, not capitalized) or magnoliid complex is used by the APG II system for a clade within the angiosperms. ...
Apparently there has been no system except APG II that brings these two families together in an exclusive unit. These two families have always been placed among the most primitive angiosperms. This includes the APG system, of 1998, which did not recognize such an order and placed these two families among the basal lineages in the angiosperms. Genera Canella Capiscodendron Cinnamodendron Cinnamosma Pleiodendron Warburgia The Canellaceae are a family of flowering plants. ... Genera Belliolum Bubbia Drimys Exospermum Pseudowintera Takhtajania Tasmannia Tetrathalamus Zygogynum The Winteraceae are a family of flowering plants belonging to the Antarctic flora. ...

Some (although obscure) possible synapomorphies (shared, derived characteristics) include entire leaf margins, extrorse anthers, ephemeral antipodal cells, the presence of hypostase, the presence of a nucellar cap, and raphal bundle branches at the chalaza (Angiosperm Phylogeny Website, 2005).
Within the magnoliids, researchers have identified four evolutionary lineages and clarified their evolutionary relationships: Magnoliales and Laurales are sisters, and Piperales and Canellales are sisters.
Possible synapomorphies for Canellales are a well-differentiated pollen tube transmitting tissue, an outer integument with only two to four cell layers, and seeds with a palisade exotesta (Doyle and Endress, 2000).
The family is found tropical climate regions in the Afrotropic and Neotropic ecozones, including South America, the West Indies and Florida, East Africa, and Madagascar.
The APG II system (2003) assigns it to the order Canellales in the clade magnoliids.
This represents a change from the 1998 APG system, which left the family unplaced as to order and merely listed it among the basal lineages of the angiosperms.
