Corpse Flower/Elephant foot yam - Amorphophallus paeoniifolius
I wish I would have seen this when the flower was in bloom!
The ID is based on suggestions of people in the Plant Identification group in facebook and reassured by this link in Wikimedia: https://commons.wikimedia.org/wiki/File:Sulawesi_trsr_ph14.jpg
In my spotting we are looking at the maturing berries.
Here is a link showing the flower!
and another pic with a Macaca nigra next to it:
Amorphophallus paeoniifolius, the elephant foot yam or whitespot giant arum, is a tropical tuber crop grown primarily in Africa, South Asia, Southeast Asia and the tropical Pacific islands. Because of its production potential and popularity as a vegetable in various cuisines, it can be raised as a cash crop.
