[Arisaema-l] Arisaema root structure

[Peter Taggart]

I find it very interesting that a few Arisaemas might be used as human food
stuff, as I have always regarded aroids as very poisonous.

What is the botanical term for the storage organ on an Arisaema please?

I think of it as a tuber which is a swollen root such as a potato has, but
a potato is a dicot. Is the 'tuber' root or stem? Were it stem then surely
it would count as a rhizome -as with a bearded Iris?  Others here are
calling it a corm, I associate corms with Irids and regard them as stems
surrounded by compressed leaves.
An article by Tony Avant refers to it as a pseudo tuber...
