Rukam Manis trees in Taman Tugu
Rukam Manis tree is an indigenous rainforest tree amongst the 4,100 trees being added to the Taman Tugu site, selected in collaboration with Forest Research Institute of Malaysia (“FRIM”) and Malaysian Nature Society (“MNS”).
It is a small-sized tree that grows up to 14m tall. The younger tree has thorns on its trunk and branches. The tree becomes thornless with age. The leaves are narrow ovate to ovate-oblong, measuring about 10cm long and 4cm wide. The tree produces fragrant flowers. Male flowers and female flowers are borne on separate tree. The fruits are round-shaped 1cm-3cm in diameter which ripen to dark-reddish purple to purplish black with 4-5 seeds.
The fruits are edible and most commonly used to make jelly and jams. The leaves and bark contain tannins and are used to treat diarrhea. The trees are also commonly planted for ornamental purposes.
These trees grow on well-drained soils or fertile loamy soils and are native to Malaysia, Thailand, Myanmar, and Nepal.
