[Arisaema-l] Arisaema root structure

[aaron floden]

So, if the "tuber" is a continuation of the stem and it is replaced annually it is a corm in some species. The shape may be discoid, spherical, or ovoid, but that does not change what it is.

 Like Greg said, there are rhizomes present on some species. In those it is akin to Trillium and only the back end of it slowly decays as the growing end continues. These are not replaced each season. Rhizomatum and "decipiens" are both like this in Vietnam.

Why all the confusion?

A. rhizomatum and decioiens are both listed as rhizomes.
I collected rhizomatum living in very boggy, dark conditions and it 
certainly looked like an Iris rhizome.
