Caesalpininae

Caesalpininae is a subtribe of flowering plants in the family Fabaceae, which is the bean or legume family. This subtribe is part of the larger subfamily Caesalpinioideae. Plants within Caesalpininae are characterized by their distinct floral structures, often featuring a zygomorphic (bilaterally symmetrical) symmetry and a prominent banner petal. The leaves are typically pinnately compound.

The distribution of Caesalpininae is pantropical, meaning species can be found in tropical regions around the world. They are often found in a variety of habitats, including forests, savannas, and even arid environments. Many species in this subtribe are trees or shrubs, contributing significantly to forest ecosystems.

Economically, some members of Caesalpininae have importance. For instance, certain species yield valuable timber, while others are used for medicinal purposes or as ornamental plants due to their attractive flowers. The exact taxonomic classification and relationships within Caesalpininae are subjects of ongoing research, with genetic studies continually refining our understanding of its diversity and evolutionary history. This subtribe represents a significant component of the legume family's biodiversity.
