Thorn forest occurs in several places in Mexico, not just in the Yucatan. Along the Pacific coast of southern and central Mexico as far south as Acapulco there's a lot, and pockets of it appear in Tamaulipas and Veracruz. Wherever it appears in Mexico, members of the Bean Family, the Leguminoseae, are foremost among the woody plants, and these trees and bushes usually bear spines and/or thorns. The main Bean-Family genera are Acacias, Caesalpinia, Cassia and Mimosa.
