In the Yucatan no plant group contains more species of trees and bushes than the Bean Family, the Fabaceae -- also known as the Legume or Pea Family. Usually it's relatively easy to recognize members of the Bean Family because they produce legume-type fruits, plus the vast majority of Bean Family members bear compound leaves. Compound leaves are those divided into leaflets.

However, remember that in the Yucatan several common tree and bush species bear perfectly nice compound leaves, but they aren't members of the Bean Family. The legume-type fruit is the clincher.
