Thanks, Dave, that's very interesting.  I've been hitting the books since I 
posted and I've learned, in additon to what you and Zach have helped me 
with, that the Arum family is quite large.  I've also discovered that there 
are 3 species growing in my state that may prove useful in an aquarium or 
as a pond plant.  They are:

Orontium aquaticum (Goldenclub)
Peltandra virginica (Green Arrow Arum)
Symplocarpus foetidus (Skunk Cabbage)

Of these three, O. aquaticum probably has the most potential.  P. virginica 
appears to be a relatively large plant from the pics I've seen and it's 
leaf shape resembles my Rhododendrons to some extent.  S. foetidus is 
unusual looking and I'm not quite sure what to make of it at this 
point.  I'm thinking the last two are probably more suited to emersed culture.
