A tree of up to 18m, Adinandra dumosa is the dominant species in the Adinandra belukar forest, the forest type in Kent Ridge. The leaves are very easily identifiable; being folded upwards along the mid-vein, with the entire leaves also pointing upwards along the branch. The leaves also have indistinguishable secondary venation. The new leaves are yellowish to reddish in colour.

Interesting Facts:

Tiup-Tiup is such a common tree in the Adinandra belukar that the forest type is named after it! Its flowers usually does not open at all thus suspected by Corner (1997) to be self-pollinated. The seeds are dispersed by small fruit bats which suck out the pulpy contents of the fruit and disgorge the seeds (Corner, 1997).

One of the many Tiup-Tiup trees in Kent Ridge.

Bark, mostly gaining a rusty color from fungus.

Characteristic upward pointing leaves.

The white flower is almost always unopen.
