III. SOME NEW COMBINATIONS REQUIRED BY THE 

 INTERNATIONAL RULES. 



By C. a. Weatherby. 



While employed at the Gray Herbarium during the summer of 

 1911 I was engaged in determinative work and in the re-arrangement 

 and incidental revision of certain groups, notably the Nyctaginaceae. 

 In the course of these activities it was found impossible to name certain 

 species in accordance with the provisions of the International Rules of 

 Botanical Nomenclature without employing new combinations. I 

 have been requested to put these names on published record and they 

 may be stated as follows:
