Now it is not to be supposed that this exhausts the list, but 

 most of the names here mentioned have received practically 

 universal recognition, and are to be found, accepted without 

 question, in such works as those of DeCandolle, of Bentham & 

 Hooker, and of Engler & Prantl. Some of the above-mentioned 

 chloronyms, in fact, if deprived of their validity under this " un- 

 written law," leave their respective genera nameless ; such are 

 Desfontainea (^Linkia Pers. being a homonym of Linkia Cav.), 

 Napoleona and Dnrvillaea. Surely it is Professor Greene's solemn 

 duty to propose tenable names for these genera. 



Modern chloronyms, as everyone realizes, are very abundant, 

 and in practically every case they are without available syno- 

 nyms ; it is to be hoped, of course, that Professor Greene will 

 increase the burden of synonymy (for that is all it is likely to 

 amount to) by furnishing names wholly unexceptionable in form 

 and derivation. For instance, twenty years ago there was Jio 

 genus dedicated to Professor Adolf Engler, of Berlin ; now, be- 

 sides the first, Engleria O. Hoffm. (1889), there are the following 

 chloronyms, awaiting substitutes from which Engler's name has 

 been eliminated : Englerella Pierre (1891), Engierophoc7iix'K\intz& 

 (1891), Englerastnnn Briquet (1894), Englerodaphne Gilg (1894), 

 and Englerina Van Tieghem (1895). Surely there is a broad 

 field opening for Professor Greene's activities. 



After all, one of the greatest difficulties attending the applica- 

 tion of the "unwritten law" lies in the fact that derivation, not 

 form, must be the factor determining whether a given name is
