  • Not a single picture of a true yam in this presentation! Despite the words about true yams (Dioscorea) and sweet potatoes (Ipomoea) in the text slides, borrowed from Wikipedia, ALL of the pictures are of Ipomoea. If anyone didn't know the difference between true yams and sweet potatoes before, they would be even more confused after looking at this presentation. Why was this made?
