Angiosperms are a group of spermatophytes (seed-bearing plants). They share the ability to flower to reproduce. This ability is considered to be a novelty technique evolved some 140 million years ago to involve mobile animals (insects) into their reproductive process, which greatly helps pollinisation. As a matter of fact, it is nowadays the dominant group of land plants.
The group is subdivided into eight divisions:
- Amborella, a rare single species shrub from New Caledonia;
- Nymphaeales, a group including water lilies;
- Austrobaileyales, about 100 species, including notably the star anice;
- Chloranthales, several dozen aromatic plants
- Ceratophyllum,6 aquatic plants popular in aquariums
- Magnoliids, some 9,000 species, including magnolia and laurel
- Eudicots, some 175,000 species, including sunflowers, petunia, apple trees and oaks.
- Monocots, some 70,000 species, among which all of the grasses, orchids and palm.
