  Apiaceae
The Apiaceae is one of the large families of angiosperms, having around 300 genera and 2,500-3,000 species.
In the Apiaceae, the stamens usually mature before the pistils, a situation which is called protandry; if the pistil matures first, the term is protogyny.
The gynoecium of the Apiaceae consists of a single, bicarpellate pistil with an inferior ovary.

The Apiaceae are mostly temperate herbs almost always with umbellate inflorescences comprising about 300 genera and 3,000 species that are commonly further distinguished by the presence of hollow stems and sheathing petioles.
The leaves are nearly always alternate and pinnately or palmately compound or more than once compound; stipules are generally absent.
However, the inflorescence type and floral construction are still typical for the family.
