The morphological characteristics of the fruits and seeds, germination and seedling growth performance of Ipil-Ipil (Leucaena leucocephala (Lam.) The dark brown seed pods are flat, roughly 4 to 6 inches long, with about 20 seeds. L. leucocephala constitutes a threat to native biodiversity. The use of L. leucocephala as an agroforestry species continues to increase its spread and it is from such plantings that it often spreads to degraded lands, livestock pastures, forest plantations and wild vegetation areas. Flowers grow clustered on the end of branches. It forms a small to medium-sized thornless tree 3-15 (-20)m tall and 5-50cm bole diameter. The leaves (up to 35 cm long) are twice-compound (bipinnate) and have 3-10 pairs of branchlets (pinnae). There are no known mechanical controls for lead tree. Lead tree is a prolific seed producer.
