This one proves to be elusive and difficult to cultivate.
I believe it requires a very high level of humidity and a cooler climate like the ones in highlands.
Apparently this one is native to Cameron Highland. ( I hope I got the correct ID)
It has a very fussy feel similar to Begonia Acetosa.
I have yet to successfully cultivate this one.
A lot of the separated clumps from the main pot didn't survive
but this one appears to be stable for now.
It does have the velvety furry feel on the foliage and coloration is almost similar to Fire Flush Begonia.
