The Fabales is an order of dicotyledenous flowering plants with 3 families, Caesalpiniaceae, Fabaceae (Syn. Leguminosae), Mimosaceae, collectively known as Legumes.
The Fabales includes herbs, vines and trees with stipulate compound leaves. One of the unifying characteristics is the dehiscent seed pod with seeds present in a row, sometimes in individual sections. Flowers have 10 or more stamens. A common feature is symbiosis with nitrogen-fixing bacteria, which reside in special root nodules and assist the plants' growth on poor soils.
The Fabaceae includes several succulent, caudiciform plants in the genera
Cassia, Dolichos, Elephantorrhiza, Erythrina,
Neorautenania, & Senna.
