Discussion
Gliricidia sepium is native to seasonally dry neotropical forests of Mesoamerica and is now widely introduced in tropical regions (M. Lavin and M. Sousa S. 1995).
Economic uses of Gliricidia sepium were reported by C. E. Hughes (1987). The wood is used in construction, the leaves for medical purposes and livestock fodder, and the tree is cultivated as an ornamental, as shade for coffee and cacao trees, and as part of a living fence system. Common names in Latin America, including madricacao, madriado, and mataratón, reflect the broad economic importance of this species.
