Herbaceous plants that have two cotyledons in their seeds are called dicots. The family of dicotyledonous plants is called dicotyledonous family. Dr. Arthur Cronquist (1981) grouped all herbaceous plants into 380 genera. Among them, the number of two-seeded tribes is 315. The first family of dicots is Winteraceae, the 102nd family is Gadhasadhapavadhava and the last is 315th family Asteraceae.
