  Re: [aroid-l] tubers vs. bulbs vs. corms

I think the appropriate way to distinguish between "tuber" and "corm" is that
a tuber is a modified rhizome (a horizontal underground stem) and a corm is a
modified vertical stem. A tuber may produce roots or buds at any point on its
surface whereas a corm retains an approximate cylindrical symmetry (except
when splitting) with a cental bud and with roots produced at the edge of a
circle, usually at its base. I think the so-called "consensus" was incorrect.
