The legume family, former known as leguminosae, is a large one, with
members as varied as vegetables (peas and beans), garden flowers (sweet
peas, baptisia), shrubs (indigofera, bush clover), and trees. They all
have podded fruit, and have nitrogen-fixing nodules at their roots, through
a symbiotic relationship with soil micro-organisms.
