I don't know ... mention in English the name of the tree that has pointed to a crystal shaped fruit, you mean ... But I know and have seen the plants that you mean ... I mentioned ... using the language GAYO (Aceh). The name of the plant is "IOK ATE"

Information: IOK ATE
Plants grow a lot around bushes around East Aceh. Located in the village: "BUKIT JOUK". Banda Alam Regency, East Aceh.
This plant has a fruit measuring 10 cm to 15 cm. Protected by fine hairs on nuts. If the nut's hair is touched by your skin, it will cause intense itching.

This is a map of the location of the IOK ATE factory.
