Florida palm a new genus, US scientists discover
• Keys palm more tolerant of cooler climes
• New edition of Genera Palmarum will soon be available

It was a case of mistaken identity that lasted more than a century.
A Caribbean palm that is well-known and widely grown in South Florida, the Keys thatch palm, is no longer what it was: Thrinax morrisii.
Instead, the palm turns out to be a different genus, say genetic detectives Scott Zona of Florida International University and Carl Lewis at Fairchild Tropical Botanic Garden. The scientists established the new genus Leucothrinax, with the thatch palm the single species. Its new identity: Leucothrinax morrisii.
The Keys thatch palm is known to be more tolerant of cold than the other Thrinax species. It grows naturally in Florida Keys and several other places in the Caribbean, posing as a respectable Thrinax ever since it was first named by German botanist Herman Wendland in 1892.
Yet Lewis, who specializes in tracing family relationships among palms, said, “When we ran the DNA, this one really stuck out”.
Why the mistake?
Because early palm botanists found it hard to carry whole plants back to European botanic gardens for exact identification, Lewis said, they often just used a leaf or perhaps flower stalks. As a result, the identities sometimes were off track. With the revision of a scientific encyclopaedia of palms, Genera Palmarum, those identities have been under scientific scrutiny.
The newest edition of Genera Palmarum, which has been years in the making soon will be available to palm growers and scientists. Lewis is one of the authors.
“It’s nice to have a local part of the story,” he said.
The “leuco” part of the Keys thatch name means white and refers to the whitish undersides of the leaves and the flower stalks.
