Try the Fairchild Botanical Gardens in Miami. Contact Dr. Terrance Walters
there. Sorry, I don't have his email address. Snail mail is as follows:
Dr. Terrance Walters, Director of Research
11935 Old Cutler Road
Miami, FL 33156
The Mongomery Foundation is the research arm of Fairchild. They have an
excellent collection of Palms.
Hope this helps.
