In over seven years living in Thailand, I have only seen this plant one time. At first I thought it was dying but when I went back to see it again, it is really alive. I think it is some type of "fly trap", but nobody seems to know. The "cups" are large enough to hole about 1/4 cup water and on the bottom is some black dust. As much as I wanted, I did not put my finger in it or smell it. Does anybody recognize it?
