The Faboideae are 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 herbaceous plants. Members include the pea, the sweet pea, the laburnum, and other legumes. The pea-shaped flowers are characteristic of the Faboideae subfamily and root nodulation is very common.

Genera

The type genus, Faba, is a synonym of Vicia, and is listed here as Vicia.

Systematics

Modern molecular phylogenetics recommend a clade-based classification of Faboideae as a superior alternative to the traditional tribal classification of Polhill: Note: Minor branches have been omitted.
