Faboideae

Faboideae is a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family.
This subfamily is widely distributed and members are adapted to a wide variety of environments. Faboideae may be trees, shrubs or herbs. The flowers are usually papilionaceous and root nodulation is very common. Vetch, Laburnum, and Sweet pea are all members of Faboideae.
