Wow! I didn't know they had these in the Philippines!
I would have definitely tried to find one.
I have been intrigued by this flower since i was a young boy and i did a presentation on them in like the 3rd grade. But i think mine was on the amazon forest or something like that.
Can you tell me more about where in Negros you saw it ?
