Despite a common (trust us, it's not just you) misconception, sweet potato (Ipomoea batas L. Lam) is not at all related to potato (Solanum tuberosum), nor to the true yam (Dioscorea batatas). In fact, they are all quite different. Sweet potato is a root crop, and potato and yams are tuber crops. Even researchers sometimes get confused that their publications mistakenly relate the crop species and data.
