The term angiosperm fundamentally changed in meaning in 1827 with Robert Brown, when angiosperm came to mean a seed plant with enclosed ovules. [35] [36] In 1851, with Wilhelm Hofmeister's work on embryo-sacs, Angiosperm came to have its modern meaning of all the flowering plants including Dicotyledons and Monocotyledons.
Dicotyledon plantlet Young castor oil plant showing its prominent two embryonic leaves (), which differ from the adult leaves. The dicotyledons, also known as dicots (or, more rarely, dicotyls), [2] are one of the two groups into which all the flowering plants (angiosperms) were formerly divided.
Nymphaea alba, from the Nymphaeales. The basal angiosperms are the flowering plants which diverged from the lineage leading to most flowering plants. In particular, the most basal angiosperms were called the ANITA grade, which is made up of Amborella (a single species of shrub from New Caledonia), Nymphaeales (water lilies, together with some other aquatic plants) and Austrobaileyales (woody ...
Angiosperms, plants that produce flowers and generate their seeds in fruits, encompass about 330,000 species and comprise about 80% of the world's plants. They include, among others, all the major ...
The monocots form one of five major lineages of mesangiosperms (core angiosperms), which in themselves form 99.95% of all angiosperms. The monocots and the eudicots are the largest and most diversified angiosperm radiations, accounting for 22.8% and 74.2% of all angiosperm species respectively. [43]
The fossil history of flowering plants records the development of flowers and other distinctive structures of the angiosperms, now the dominant group of plants on land.The history is controversial as flowering plants appear in great diversity in the Cretaceous, with scanty and debatable records before that, creating a puzzle for evolutionary biologists that Charles Darwin named an "abominable ...
Alectryon subdentatus is a tall shrub/small tree in the Sapindaceae family, and was first described in 1863 as Nephelium subdentatum by Ferdinand von Mueller, [2] [3] and then in 1879 was assigned to the genus, Alectryon, by Ludwig Radlkofer.
This is the top level category for the angiosperms (flowering plants) and their subdivisions (clades, orders, families, genera and species).; Most entries should be put in one of the subcategories, but a small number of articles relating to clades, orders, families or genera too small to have their own categories are put directly here.
