From Buckeye: Here is the background: A friend of ours named Rodney got these from a friend named "Rennie". Rennie is from Grenada. His wife is from Trinidad. Her parents collected these seeds in Trinidad (possibly Landrace) and gave them to Rennie. Rennie then gave to Rodney who distrubuted them to friends in the United States. The Brown version seems to be a little more rare.
