Botanical Description
A low tree (no more than 5 meters) with a wide domed crown .

Inflorescences are spherical, light yellow, grow several in groups, axillary . The flowering period falls on January - March . Do not smell.
The pods are narrow with the arrangement of seeds in length (unlike koa, in which the seeds are arranged across). Seeds are small relative to koa seeds. Seed quality depends on humidity: in a dry climate - high.

The wood is solid and dense.
Distribution
The tree is the endemic of the Hawaiian Islands (islands: Molokai , Lanai , Maui , Hawaii ) [2] . There is a danger of extinction.
Pests and Diseases
The disease is susceptible to rhizome. When bacterial symbiosis forms, a strong pungent odor appears. To avoid disease, do not recommend the use of pesticidal fertilizers.
Care
Fertilize the plant after young leaves appear with nitrogen fertilizers . Trees do not require pruning. The lower branches self-destruct. But if pruning is nevertheless necessary for the formation of the crown, then it should be minimal and without severe damage to the tree.
Watering is moderate. Young trees compensate for the lack of water with maximum light absorption. In drought, watering is recommended several times a month. Flooded plant dies. It tolerates drought and wind.
The soil is clayey, organic and ash. The roots are located close to the surface of the earth. It is not recommended to arrange walkways next to the tree.
