According to Poli, the naturalist, from whose manuscript and drawings this genus 
was recognized by Abildgaard, was named Caulini, which is properly rendered 
into Latin by Poli in the form Cavlina. The rendering Cavolina, though inexact, 
has precedence and must be adopted, though there is some doubt whether the 
name of Bruguiére or Abildgaard has precedence, both having been published in 
the same year. Gioeni figured this genus, but did not name it, hence it is inaccu- 
rate to refer to him as the author of the name, as too often has been done.
