Ilex crenata is one of the most important landscape and nursery plants in 

 the United States. This comprehensive international checklist is the first 

 publication to document all of the cultivars and wild-origin variants of 

 Ilex crenata. Introductory sections contain the following: a detailed 

 morphological description of the species; an evaluation of its current 

 status; cultural, nomenclatural, and taxonomic histories; an explanation of 

 the format; and the technical bases for validation of cultivar names in 

 accordance with the "International Code of Nomenclature for Cultivated 

 Plants — 1980." The section entitled "Alphabetical List of Documented 

 Epithets" provides full documentation for 436 garden and wild-origin 

 germplasm entities (170 are legitimate, 266 are illegitimate or 

 controversial), including origins, sources, descriptions, histories, 

 international registrations, original and other pertinent references, and 

 synonyms. Eighteen new cultivar names are validly published for the first 

 time, and a simple list of 1 12 illegitimate names (which have no 

 documentation previously discovered) is provided. This publication is 

 particularly useful for botanical historians, systematists and 

 nomenclaturalists, plant experts of various trades, and consumers. 



Keywords: Cultivar names, documentation, illegitimate, international 

 registration, Japanese holly, legitimate, nomenclature, synonyms,
