Amorphophallus - unknown species

Unknown #1 this plant looks something like a paeoniifolius but the petiole is smooth and a bit darker.  It's a strong grower.

Unknown #2 Here's one that remained dormant until mid August. It's tiny and hopefully will grow sufficiently to survive the winter dormancy.

Unknown #3 This was dormant until late August when it sent up a shoot which has proved to be an inflorescence. I'll take more photos daily until the bloom is open. Hopefully I can get an ID from the bloom. Identified as possibly "operculatus"... 4 days later the bloom is still not bloom.  5 days later I gave up and sliced it open for proper ID.  On the 6th day, there is some pollen, then I broke off the bloom and shot photos of the tuber.

Unknown #4 This has been growing all season.  The yellow dots on the lamina certainly look something like a mite infestation but I haven't treated for mite and I don't see any mites.

Unknown #5 The lamina has begun to deteriorate so I'm not photographing it.  Besides I burned it pretty badly in sunlight hoping to grow a large enough tuber to bloom next year.  I had a napalensis and yunanensis.  One died the other survived, both labels fell off.  This is one of those two.  Which? Identified as napalensis.
