Description

edit

Katmon is a medium-sized evergreen tree that grows as high as 10 to 15 meters. Its trunk is erect and the branches usually start midway of the trunk. The tree is buttress-forming, evergreen, and shade tolerant. The bark is smooth with shallow fissures. The leaves are leathery, shining, ovate, elliptic or oblong-ovate, about 12 to 25 centimeters long, and coarsely toothed at the margins. Its flowers are white, large, showy, and about 15 centimeters in diameter with reddish pistils and stamens. The edible fruits are rounded, about six to eight centimeters in diameter, with large fleshy sepals tightly enclosing the true fruit.

Uses

edit

The fruit, called "elephant apple", has a diameter that is around five to six centimeters. It contains a soft, fleshy, green, and edible pulp with a flavor similar to a sour green apple. It is used to make sauces, jams, and flavoring for fish. The fruit's acid is mixed with sugar to make a traditional cure for cough. It is also used to clean the hair.

The tree is harvested for its timber[1] as it is suitable for furniture and cabinet making. The wood has a beautiful silver grain similar to a quartered oak. A red dye can also be obtained from the bark.[3]
