Nice Paul but I have to agree with Paphioboy this year. It doesn't look pure niveum. The petals hanging down do look like bellatulum influence. Is it tiny like a thainum?
Both flowers are wonderful; but, I agree too....it seems to have some bellatulum in there. It's possibly a Psyche x niveum? It's common to see mislabelled niveums, which is very frustrating.
