Rukam is a fruit which has originated in South East Asia. It can be se seen bothg wild as well as cultivated in Malaysia. It has also been introduced into Thailand and India. A small tree, trunk and old branches usually crooked, furrowed, branched near the base; woody, simple or branched spines, usually absent in clonally propagated trees. Leaves ovate-oblong or elliptic, shiny dark green above, brownish-red and drooping when young, margins coarsely toothed. Fruits a globose, depressed-globose to obovate berry, light-green to pink or purplish-green to dark red with whitish, juicy, acid pulp, crowned by the small peg-like styles set in a circle. The ripe fruit can be eaten raw. Usually people rub the fruits between the palms of the hand before eating because bruising the flesh eliminates astringency. Fruits are also served in rujak, a fruit salad with spicy sauce, pickled, or sweetened with sugar to make jam or confectionaries. The young leaves are eaten raw in side dishes. Immature fruit is used to prepare traditional medicine against diarrhea and dysentery. The juice of the leaves is applied to inflamed eye-lids. In the Philippines a root decoction is taken by women after childbirth. Rukam grows best under humid tropical conditions. The tree appears to be fairly adaptable to a range of temperature, rainfall and soil conditions. Rukam is usually grown from seed, but the tree produces root suckers which can be used for vegetative propagation, e.g. of spineless trees. Budding or grafting, also on other Flacourtia species, is possible. In Indonesia, the plants are budded on Flacourtia inermis seedlings. The young plants, if nursed well, bear much larger leaves than the full-grown tree. Shoot growth occurs in more or less synchronous flushes. The length of the juvenile phase is not known. In Java the trees flower between June and August; the fruit ripens after about 14 weeks. Occasionally flowering occurs at other times of the year. Rukam has receives little attention and it is so often confused with other species, particularly Flacourtia inermis. There is wide variation in the fruits.
