The fact that you got so much white out of the two brachypetalums is really nice - I suspect that it was the delenatii's repressing of the yellow-green in the concolor that gave you the white - plus the niveum seem to have been upsized by the P. concolor, although the concolor shorter stem is evident as suppressing both the delenatii's and the niveum's tendency to stand a good bit taller.
A very healthy specimen named after one of the pre-emintent and fascinating orchid frontiersmen!
