Amorphophallus operculatus

I received this Amorphophallus several years ago labeled as "cicatricifer".  The original label is partially visible.  It's quite attractive and has been a reliable grower (although this year has been very late to break dormancy).

A couple issues, though, are making me question the accuracy of the ID.  First of all, I purchased an operculatus recently and the two plants are extremely similar.  The IAS photos of cicatricifer make the leaflets look slightly wider.  Second, the tubers have been elongated rather than the described globose tubers of cicatricifer.  So if the original label is wrong and if this is actually operculatus, then I'm happy with the plant but am on the hunt for cicatricifer.
