Geophyte - an uncomfortable definition ?

Angelo's letter was thought-provoking. My thoughts now dwell on some
much commoner plants than he mentioned. Scarlet runner beans produce
a big underground tuber. A little tour through the vegetable market
reveals lots of tubers: potatoes, sweet potatoes, jicama, various
Chinese roots - one is a Stachys I think.
