The Umbelliferae are a family of dicotyledon plants that includes about 3000 species divided into 420 genera present in all temperate areas of the world.
It is a relatively homogeneous family, characterized by a typical inflorescence.
The dried fruits are diakenes that split into two when they ripe, each part containing a seed. They are very diversified in their external forms: there may be hooks or thorns, protuberances or hairs, sometimes wings and they are important in order to observe the determination of the species.
