Julius,

A. dracontium is distinguishable by its single compound leaf with 7-12
leaflets, its small green sheathing, and its long-caudate spadix
appendix.
 
A. triphyllum is 3 foliate. There are several ssp. which vary greatly in
size and other characteristics.
However, A. triphyllum ssp quinatum (Buckley) Hutt., which has a very
restricted range in the deep south and is found only in Georgia, northern
Florida, Alabama, Mississippi and Louisiana, is penta-foliate.  It grows
in moist, shaded situations.  It tends to be smaller than the other
subspecies and its leaves are usually glaucous beneath and penta-foliate
though they are sometimes tri-foliate or lack gaucescense.  The spathe
tube is smooth and topped by broad, flaring, but not depressed flanges. 
The spathe blade is unmarked green and oval or orbicular with an abruptly
apiculate tip.  The cylindrical spadix appendix is very slender and
curved toward the opening of the spathe.  Its chromosome number is 28.

Yours sound too big to be ssp. quinatum but it's the only American
species that is penta-foliate so it
is easy to spot.

If you can handle WordPerfect files, I can send you Huttleston's KEY to
A. triphyllum which
also comments on the other two North American species.
