Thanks for the info.. I guess that ends my quest then!

Not so fast! :-) A Google search indicates that a number of the Fort
Caroline Orchids were registered by Dr Henry Wallbrunn, and searching on
that name suggests that he may still be active, as a Phal. mannii
belonging to a Henry Wallbrunn was awarded a blue ribbon in April 2004
at the Gainesville Orchid Society:

So you might try contacting Mr Wallbrunn via the GOS and see if his
collection still includes the plants he registered!
