Fabaceae (Leguminosae) (pea, bean)
- Leaves often pinnately or palmately compound
- 5 petals form "banner", "wings", and "keel" in zygomorphic (bilaterally symmetric) flower
- Superior ovary ripens to form a legume ("pod"), whose two sides split apart with the seeds attached to one edge of the valves
- Symbiotic rhizobia in root nodules fix nitrogen
