Below are 2 similar photographs, one with flash on and one without. Not much changes to the C. villosa I had after close to 3 months of cultivation, just 3 new leaves.
I was lucky to obtain a specimen of C. villosa 'Sumatra' from my explorer friend. This is how the leaves looked like, very normal and typical I would say:
Hopefully it will grow well in my emersed cultivation tank...
