C. nurii Furtado 'Platinum'

The cultivar 'Platinum' is found on Lingga island in the Riau Archipellago province of Sumatra. Each stream has several patches with the broad leaved C. nurii var. nurii. This special one has white veins as a permanent character and is therefore attractive for aquarists. In 2014 Kettner described this cultivar.
