Pinellia tridentata ?

[Brian Cook]

I was recently sent some seeds labeled Pinellia tridentata. I can not
find any information on the net about this particular species and am
wondering if anyone is familiar with this one?  The only information I
have is that it is apparently of Chinese origin. I would appreciate
confirmation of the name (or synonym) and perhaps the URL of a
photograph if one exists.

Thanks 
Brian
