Recent studies, as by the APG, show that the monocots form a monophyletic group (clade) but that the dicots do not (they are paraphyletic). Nevertheless, the majority of dicot species do form a monophyletic group, called the eudicots or tricolpates. Of the remaining dicot species, most belong to a third major clade known as the magnoliids, containing about 9,000 species. The rest include a paraphyletic grouping of primitive species known collectively as the basal angiosperms, plus the families Ceratophyllaceae and Chloranthaceae.
What type of groups do monocots form, based on a recent APG studies? Eudicots or tricolpates are part of a monophyletic group formed by what species? What third major clade can many dicot species be found in? How many species dicot species are magnoliids? Basal angiosperms are what type of grouping of primitive species?
