Peter Beales refused to accept several errors, this one included. Yes, Spray Cecile Brunner is a different rose from Cecile Brunner -- it's a sport of the latter, just as Climbing Cecile Brunner is a sport. They were tested and found to be genetically indistinguishable. Similarly, Old Blush and Archduke Charles are different roses, but the latter is a sport of the former, so genetically they are virtually identical.

What was found in California matches old photos and descriptions, and I think Malcolm Manners included it in a "paternity test" to see if it matched up to its purported parents, but I don't know if the results were published yet.
