The basal eudicots are a group of 13 related families of flowering plants in four orders: Buxales, Proteales, Ranunculales and Trochodendrales. [1] [a] Like the core eudicots (the rest of the eudicots), they have pollen grains with three colpi (grooves) or other derived structures, [4] and usually have flowers with four or five petals (sometimes multiples of four or five, sometimes reduced or ...
Basal eudicot is an informal name for a paraphyletic group. The core eudicots are a monophyletic group. [11] A 2010 study suggested the core eudicots can be divided into two clades, Gunnerales and a clade called Pentapetalae, comprising all the remaining core eudicots. [12] The Pentapetalae can be then divided into three clades: [citation needed]
The traditionally listed differences between monocots and dicots are as follows. This is a broad sketch only, not invariably applicable, as there are a number of exceptions. The differences indicated are more true for monocots versus eudicots. [35] [36] [37]
Sections from the whole tree can be transcluded separately. For example, the following code extracts the monocot tree. The sections are marked in the template using <section begin=SECTION_NAME /> and <section end=SECTION_NAME />. In this example the SECTION_NAME is Monocots.
Recent studies, as per the APG, show that the monocots form a monophyletic group (a clade), but that the dicots are paraphyletic; nevertheless, the majority of dicot species fall into a clade with the eudicots (or tricolpates), with most of the remaining going into another major clade with the magnoliids (containing
Evolution of angiosperms shown in diagram format, per APG IV. The APG IV system of flowering plant classification is the fourth version of a modern, mostly molecular-based, system of plant taxonomy for flowering plants (angiosperms) being developed by the Angiosperm Phylogeny Group (APG).
The APG system (Angiosperm Phylogeny Group system) of plant classification is the first version of a modern, mostly molecular-based, system of plant taxonomy.Published in 1998 by the Angiosperm Phylogeny Group, it was replaced by the improved APG II in 2003, APG III system in 2009 and APG IV system in 2016.
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG).
