Definitely looks like one of the Pseudodracontiums, as they used to be called, now moved into Amorphophallus, even though they flower at the same time leaves are up.
In 2009 these were available from a plant distribution from MOBOT:
79452 = H.AM.162
Colombia. Valle del Cauca.
Queremal to Anchicayá, ca. 10 km W of Queremal.1100 m 03.33.00N
Thailand. Si Chang Island (Maxwell-683) (HAM 258)
79453 = H.AM.209
latifolium has green petioles with green spots, harmandii has brown petioles with dark spots. I suppose you can look the others up on the IAS website. Be careful, there is an Am. harmandii, and an Am. pseudoharmandii, you want the latter.
Attached are a few photos of my pseudoharmandii, it doesn't look quite like yours.
I think the HAM accession numbers were originally from Wilbert Hetterscheid? He also used to do distributions, maybe back around 2002 or so?
