Re: misidentified tuber?
If your plant is anything like T. (S.) venosum, it should have a "pedate"
leaf, i.e. foot-shaped. The leaflets of Arisaema concinnum are grouped in a
circle, so the circumference of the entire leaf-blade is circular. Below
ground you may find that T. venosum produces sessile offsets, while A.
concinnum should be producing offsets on long, rhizomatous runners. I also
think that A. concinnum never produces as extravagantly spotted/blotched
leaf-stems as T. venosum does.
