The eudicots or eudicotyledons are flowering plants that have 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-magnoliid dicots.

真双子叶植物（学名：eudicots）是被子植物的分支之一，由道利（Doyle）和霍顿（Hotton）在1991年提出来的，是划分被子植物门中“非木兰类双子叶植物”，也就是说花粉具有三孔的植物类群。

真双子叶植物[1] （学名： eudicots）是指 花粉 具有三孔（具三叉沟型花粉粒）的植物类群，属于 被子植物 的 演化支 之一。 该植物学术语由进化植物学家 詹姆斯·A·道尔 和古植物学家 卡罗尔·L·霍顿 在1991年所倡议，其划分出了 被子植物门 中的“非木兰类双子叶植物”，包括了绝大部分 双子叶植物纲 中的种类，而其他没有包括进去的双子叶植物被称为“ 类双子叶植物 ”或 古雙子葉植物 （并系群）。 有时也将真双子叶植物分支称为“三孔花粉组”，因为它们的花粉都具有三个或三 …

2025年2月14日 · Angiosperm - Eudicots, Flowering Plants, Monocots: The eudicots are characterized by pollen that fundamentally has three furrows or pores (tricolpate), in contrast to the single pore or furrow of the monocot and basal dicot group (monosulcates).

Compare and contrast monocots and eudicots. Differentiate between monocot and eudicot flowers and leaves. Of over 400 families of angiosperms, some 80 of them fall into a single clade, called monocots because their seeds have only a single cotyledon.

Monocots and eudicots are to major lineages within the angiosperms. There are several ways to differentiate between these evolutionary groups, including the number of cotyledons, number of floral …

The eudicots are one of the most diverse groups of flowering plants in terms of floral and vegetative shape, growth form, habitat, and association with animals for pollination, seed dispersal, or nutrition.

The eudicots (Eudicotyledoneae, sensu Cantino et al., 2007) are a large, monophyletic assemblage of angiosperms, comprising roughly 190,000 described species, or 75% of all angiosperms. The monophyly of eudicots is well supported from molecular data and delimited by at least one palynological apomorphy: a tricolpate or tricolpate-derived pollen ...

2022年2月2日 · We show that Buxus and Tetracentron are both characterized by independent WGDs, resolve relationships among early-diverging eudicots and their respective genomes, and use the RACCROCHE pipeline...

2015年4月9日 · The eudicots are the biggest group of plants on Earth. They make up over 75% of all angiosperms and over 50% of all plant species. New species are still being discovered and will be for a long time but estimates on the total diversity of eudicots are around 280,000 species. The group is separated into the core eudicots and basal eudicots.
