The flowers do look like the Govenia species as Matt pointed out. But the foliage is not like the few foliage pictures I could google up. I have no idea about the ID and neither did one of the leading botanists in Peru. I wish I had a better plant picture to post but everytime the plant got to looking pretty good for a picture the little tamarins would decide to smash it.
If it were in fact un-described then it can be described and named. But not by me! I'm not qualified to do the responsible research through the botanical archives to make certain it has not been described in the past. Nor would I attempt to write a paper that would need to stand up to scientific review. Species description should be done by experts familiar with the group being described.
Exploring and finding different things in nature is what I like to do! I'll leave the cutthroat paperwork part to others. The fun is in the finding and growing.
I have discovered quite a few new fish species, several of which have been described. I provided the specimens and data to qualified persons who wrote the descriptions. That is what I would do with a plant as well.
Such an amazing plant and not entirely unexpected in
your part of the world...so much yet to discover. I hope
the different environments in South America and the plants
and animals will survive long enough to be found and identified.
