Unfortunately, I can find no Onc. Wildcat in OrchidWiz or RHS. There is a Oncostele (syn. Colmanara) Wildcat. There is no awarded cultivar for 'Silver'
Potinara Triple Love is a registered hybrid. The NN is either a cultivar name or an indication that it is a genetically a diploid.
Note that cultivar names are enclosed in single quotes; e.g. 'Silver'. Is this the case on your tags? Growers can still provide cultivar names regardless of their award status.
