Acacia koa

Common Name: koa

Family: Fabaceae

Country of Origin: Hawaii (endemic)

Description: Initially, bipinnately compound leaves with 12–24 pairs of leaflets grow on the koa plant, much like other members of the pea family. At about 6–9 months of age, however, thick sickle-shaped "leaves" that are not compound begin to grow. These are phyllodes, blades that develop as an expansion of the leaf petiole. The vertically flattened orientation of the phyllodes allows sunlight to pass to lower levels of the tree. True leaves are entirely replaced by 7–25-centimetre (2.8–9.8 in) long, 0.5–2.5-centimetre (0.20–0.98 in) wide phyllodes on an adult tree.
