Here's a link to an article from the Central Florida Heritage Rose Society:

there could have been discoveries made since then.)

I think Dr. Manners is considered the ultimate authority on RMV and to my
knowledge the article you mentioned is still the most current information
available. He lists an email address on his site, if anyone cares to ask him.
Or perhaps he will see this message title and respond here. He has been known
to post here on occasion.
