Taxonomic Rank: Magnoliopsida: Fabales: Fabaceae (Leguminosae)
Synonym(s): koa haole, lead tree
Native Range: Not Found (BAIL);

Appearance
Leucaena leucocephala is a shrub or small tree that can grow up to 16 ft. (5 m) in height.
Foliage
The bipinnate leaves are about 10 in. (25 cm) long. There are approximately 12 pairs of lanceolate shaped leaflets each about 0.35-0.47 in. (9-12 mm) long, 0.08-0.14 in. (2-3.5 mm) wide. Leaflets are oppositely arranged.
Flowers
Flowers grow clustered on the end of branches. Individual flowers are white, turning brown with maturity.
Fruit
Leucaena leucocephala is a prolific seed producer. The dark brown seed pods are flat, roughly 4-6 in. (10-15 cm) long, with about 20 seeds. Seeds are glossy brown, oval, flat, 0.24 in. (6 mm) long.
Ecological Threat
In areas where Leucaena leucocephala is considered an invasive weed, it will form dense thickets and displace the native vegetation. Disturbed, cleared areas, coastal strands, outskirts of forests and canopy gaps are some locations regularly invaded by Leucaena leucocephala.
