Ryparosa scortechinii: Philosophically at MacRitchie Forest

This species was once regarded as being survived by only 2 remnant trees in the 6-hectare Rain Forest in Singapore Botanic Garden. However, I found a few small to large trees in MacRitchie over the years.


It was quite unfortunate then that not long ago I found one of 'my tree, my old friend' knocked down by a  neighbouring giant. 'A Ryparosa scortechinii killed by a Calophyllum teysmannii', I mused morbidly. The question about reality felled on me at that moment. Only I knew... probably... if a tree falls in a forest and no one is around to hear it, does it make a sound?


Now you know. Here's the fruits and photos of my tree, my old friend... it's real.
