  • As Java is not in the areas reesetee mentioned, we'll have to add Southeast Asia. Indeed I have seen this tree growing in villages in Java. I believe its name is randu in Javanese and kapuk in Indonesian, hence the origins of this word.

    Might I also add that it is excellent pillow stuffing. It is quite cool, as compared to synthetic fibres. In the tropics a night on a kapok mattress is much preferable to a night on anything else.
