Here are the samaras of the Kempas tree, Koompassia malaccensis strewn along a part of the HSBC Nature Trail at Macritichie. I guess its part of the mast fruiting that’s going on right now. Picture taken yesterday on the 11 June 2005.
The timber was once rated as Malaya’s 3rd most abindant timber tree. On a herbarium specimen that I chanced across once, I read that the Macaques eat the seed of the fruit and access it by bending the samara. The samara is twisted at the base, which enables the fruit to spin in the wind. The flowers are tiny, just 0.5 cm in diameter.
