Re: misidentified tuber?

From: "Wilbert Hetterscheid" hetter at worldonline.nl> on 2000.09.01 at 15:17:15(5324) Neil, 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.
