There is presented above a list of almost one hundred names of 
plants precisely as Linnzeus published them in 1753, hardly five of 
which are to be found unaltered in recent books of botany whether 
European or American; and this in the face of universal preten- 
sion that, beginning with the year named no specific term of any 
name is to be altered, even by the man who proposed it. On our 
side of the Atlantic one faction does indeed carry the professed 
principle of immutability to the extent of writing Catalpa Catalpa, 
Hlepatica Hepatica, and a score of other such; but even in such 
instances when it comes to writing V7z/7s tdaea Vitis idaea, Linnzeus 
is doubly amended; for they make the four words over into 
Vitis-[daea Vitis-[daea, pretending that he had l7tis-/daea, which he 
had not, though they can not bring themselves to write A/eli/otus 
Melilotus officinalis, or Filix Filix fragilis. 
If the rule that ‘‘ specific’’ names shall not be changed in trans- 
ferring a plant to another genus has any meaning whatever, then 
such Linnean names as 7yifolium Melilotus officinalis, Trifolium 
Melilotus indica, Trifolium Melilotus ttalica, etc., ought to appear 
in our botanical literature as Welilotus Melilotus officinalis, Melilotus 
Melilotus indica, Melilotus Melilotus italica, etc. For the same 
reason Polypodium Filix fragilis ought to be present as Cystopterts 
Filix fragilis or Filix Filix fragilis. We look for these in vain,
