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.

Divisions

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.
