The eudicots are the largest monophyletic group within the dicotyledons. They are distinguished from all other flowering plants by the structure of their pollen. Other dicotyledons and the monocotyledons have monosulcate pollen (or derived forms): grains with a single sulcus.
The eudicots, Eudicotidae, or eudicotyledons are a clade of flowering plants (angiosperms) which are mainly characterized by having two seed leaves (cotyledons) upon germination. [1] The term derives from dicotyledon (etymologically, eu = true; di = two; cotyledon = seed leaf). Historically, authors have used the terms tricolpates or non ...
Syncolpate pollen grains have two or more colpi that are fused at the ends. [17] [14] Eudicots have pollen with three colpi or with shapes that are evolutionarily derived from tricolpate pollen. [18] The evolutionary trend in plants has been from monosulcate to polycolpate or polyporate pollen. [14]
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 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 evolution of having one or two cotyledons may have arisen 200-150 Mya when monocots and dicots are thought to have diverged. [ 3 ] [ 4 ] Furthermore, the cotyledons in dicot seeds contain the endosperm which acts as the seed’s food storage, while in monocot the endosperm is separated from the cotyledon. [ 1 ]
They are eudicots, characterized by their flower petals growing in groups of five parts. They have two embryonic leaves, which are also known as the cotyledon. In addition, their leaves are also veined. They are from the genus Abelmoschus, family Malvacea, and belong to the clade angiosperms, and are classified as magnoliophyta. [2]
This category should contain only articles about the families of eudicots, when the articles are at the scientific name, or redirects from the scientific name in the case of monotypic taxa or articles at the English name.
