ID of photo on AlpenPix 492

[Diane Whitehead]

I have had a couple of suggestions about the identity of the AlpenPix 492
arisaema with the yellow ?-shaped spadix.  Certainly, the picture
corresponds to A. wilsonii, which apparently is sometimes called
dilatatum.  It also looks like A. asperantum because of the bumpy or spiky
leaf petiole.

I had never heard of any of these species - I guess they haven't made it
into our seed exchange yet.

Thank you for the help.
