I'm being a bit more cautious this time after suggesting the last one might have been an Alocasia.
These were growing at the 1500 to 2000 metre altitude range, some beside small streams in running water.
Another ............ aroid!
Another one sitting in water.
A close-up of the flowers (not good focus).
Without a good clear close-up of the blooms, I can't be certain, but I would lean towards an Alocasia species on that one. Possibly A. heterophylla.
LariAnn
I would have to think LariAnn has the best guess on the ID. I would not know for sure on this one. The strange thing is that it is growing in water. I found one friend who grew all his Alocasias sitting in trays of water and the all looked great. I had often tried this and watched the plants melt in to mush over night. It does seem that the roots often modify for the situation they are in slowly but a move to another area can mean death.

Brian, what type potting medium did he use?
Alocasia looks right.
What part of New Guinea was this from Tropicbreeze?
In the Owen Stanley Ranges, northern slopes of Mt Bellamy. Seemed to occupy the same range as Pandanus brosimos. Plant in the first photo would have been somewhere around the 1500 metre altitude, the others were in a group at about 2000 metres altitude (give or take a little). Latitude a little less than 9 degrees south.
Brian, I've noticed with most I've moved from dry land to water would die back severely and then recover into a large healthy plant. This is particularly with Alocasia macrorrhiza.
