In Fabales: Ecological and economic importance Various forms of leucaena (such as Leucaena leucocephala) have been developed for animal forage, firewood, and construction, as well as for the high production of nitrogen that enriches impoverished soils, especially in the Asiatic tropics. In Uganda, it was introduced in tea plantations and as a host for the vanilla orchid (Vanilla planifolia) and later planted among other crops as a nitrogen fixer. One of the principle factors limiting the use of this plant is the presence of an unusual amino acid, mimosine.
