I'm growing two different plants labeled N. faizaliana. One originates from Rob (Borneo Exotics) and the other one originates from Malesiana Tropicals. Both plants look so considerable different that I strongly suspect them being the same species. Both of my plants are quite small and so I'm not able to judge whether they are labeled correct or not:
Malesiana Tropicals clone:
Borneo Exotics clone:
So if anyone has grown these clones to a bigger size, I would be interested in what they look like when being bigger.
