Amorphophallus haematospadix
The images below of the inflorescence were taken from a gift obtained many years ago. I was sloppy and lost the plant. I've since purchased a new one and that is the source of the bottom two photos.
True to predicted form, the inflorescence had a faint pleasant odor.
The following info has been extracted from Aroideana, Volume 19, a publication of the International Aroid Society. You'll note that this is just a small portion of the extensive descriptive information available in the Aroideana 19:
