nobody can define, or Loxogramme as a whole is a valid genus. 
Currcinia has been treated in substantially the same manner. 
In Alsophila and Diplazium, there are fourteen new names 
for species which I have described as Cyathea and Athyrium. 
When the thorough revision takes place, Alsophila and Dipla- 
zium will probably disappear, and these fourteen names will 
survive as useless synonyms. However, if Christensen had not 
published these names, some one else would have done so. Even 
after the most thorough revision, there will doubtless remain 
botanists who will publish new names, and perhaps still some 
who will publish two or three names at a time for the same 
species, even if they know that their names cannot be, and ought 
not to be, generally adopted.
