It has large leaves, and large yellow flowers. The flowers open at 3 am and last only a day. The ripe fruit splits open also at 3 am, into pinkish star-shaped segments to reveal seeds covered in red arils. The plant blooms from age 3-4 and can live for 50-100 years! The Simpoh Air sends out very deep tap roots to reach underground water sources. The tree is used to detect water as it always grows near water. The special thing about this useful plant is that the leaves can be used to wrap food and can also be used by tailor birds to make nests.
Simpoh Air is used to staunch bleeding wounds, and the fruit pulp may be used to wash the hair (Brunei).
