Flower of Liriodendron tulipifera, a Mesangiosperm. Mesangiospermae is a clade that contains the majority of flowering plants (angiosperms). Mesangiosperms are therefore known as the core angiosperms, in contrast to the three orders of earlier-diverging species known as the basal angiosperms: Nymphaeales (including water lilies), Austrobaileyales (including star anise), and Amborellales.
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.
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (/ ˌ æ n dʒ i ə ˈ s p ər m iː /). [5] [6] The term 'angiosperm' is derived from the Greek words ἀγγεῖον / angeion ('container, vessel') and σπέρμα / sperma ('seed'), meaning that the seeds are enclosed within a fruit.
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 ...
This category lists angiosperm families which have been recognized historically, but are not used currently (e.g. not used in the APG III system). Currently used families are listed at Category:Angiosperm families. Non-angiosperm families (bryophytes, pteridophytes, gymnosperms) are listed at Category:Historically recognized plant families.
The rosids are members of a large clade (monophyletic group) of flowering plants, containing about 70,000 species, [2] more than a quarter of all angiosperms. [3]The clade is divided into 16 to 20 orders, depending upon circumscription and classification.
A floral diagram is a graphic representation of the structure of a flower. It shows the number of floral organs, their arrangement and fusion. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding angiosperm evolution.
This category should contain only articles about the families of angiosperms (flowering plants), 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.
