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 ...
The eudicots can be divided into two groups: the basal eudicots and the core eudicots. [10] 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 ...
Ranunculales belongs to a paraphyletic group known as the basal eudicots. It is the most basal clade in this group; in other words, it is sister to the remaining eudicots. Widely known members include poppies, barberries, hellebores, and buttercups.
The Buxales are placed within the eudicots but outside the core eudicots, in a paraphyletic group of basal eudicots. The monophyly of the order and its general position relative to other eudicots has been confirmed by many studies. [2] One possible phylogenetic tree is shown below, where the precise ordering of the basal eudicots is still ...
Khan et al. (2025) describe fossil material of palms with one metaxylem vessel in each fibrovascular bundle from the Maastrichtian-Danian Deccan Intertrappean Beds (), and interpret the studied fossils as Cocos-type palms belonging to the subfamily Arecoideae that likely grew in a tropical rainforest.
In phylogenetic nomenclature, the Pentapetalae are a large group of eudicots that were informally referred to as the "core eudicots" in some papers on angiosperm phylogenetics. [2] They comprise an extremely large and diverse group accounting for about 65% of the species richness of the angiosperms , with wide variability in habit , morphology ...
The top level category for the Eudicots — a clade of angiosperms (flowering plants) in the APG IV system (2016).; Most entries should be put in one of the subcategories of the clade (orders, families, genera and species)., but a small number of articles relating to orders, families or genera too small to have their own categories are put directly here.
The superasterids are members of a large clade (monophyletic group) of flowering plants, containing more than 122,000 species. [citation needed]The clade is divided into 20 orders as defined in APG IV system.
