Long-branch endemics -- source of the term

[Barry Roth]

I would like to know who first used the term "long-branch taxon" (i.e., a non- or little-ramified clade that is the sister-group of a much more branched clade), and/or where there is a good, citable definition of the same in print.

Also, the same question with regard to the term "long-branch endemic," which I assume means a long-branch taxon that is restricted to a particular geographic area.

Many thanks,

Barry Roth
