Kuntze made a tour around the world from L874-1876. He began 

 to study and classify his collections made on that tour in 1884 at the 

 Herbarium at Berlin. He worked there until 1887, when he went to 

 Kew, where he continued his work until the end of 1890. The result is 

 his " Revisio." It will be seen, therefore, that he did not begin the 

 work of revision in cold blood of malice aforethought, but was drawn 

 into it in the course of other investigations. In ehe-sifying his collec- 

 tions he attempted to do something more than identify them. He 

 studied them, and as a result wrote several monographs, of which he 

 published some separately and incorporated others in the present 

 work. In the present condition of nomenclature, he found that next 

 after the proper limitation of a genus or species, the determination of 

 the name to be applied was of the highest importance, and that the 

 latter had become a much more difficult task in some instances than 

 the former, as those who had worked at the one with the greatest care 

 had used little or no care in the other. He decided to examine the 

 names he applied with the greatest care and to reach as far as possible 

 a permanent result. The great extent of homonymy and synonymy
