Hi Christopher,

Such a mark is the scar of the previous inflorescence (-peduncle). It is also a clue as to the "new"tuber is built from the previous one. The old one is obviously not just "swallowed up" by the new growth but only partly and then new tissue is added. It is in fact a vertical rhizome, that builds a new module every year and discards of most of the pre-last module in the process but not all of it.
