 last definition, because it is not intended to create a  
 new terminology for these arilbreds. The abbreviation  
 “ABT” is just made available for situations in which it  
 is needed to single out arilbreds that are not ABDs or  
 ABMs.) 
 Some have wondered why these terms are used  
 rather than simpler ones like “aril-median” or “aril-med.” 
  The main reason is that the terse terms can be  
 misleading about the nature of the plants. The ASI has  
 long made a concerted attempt to educate people  
 that the term “aril” should be reserved for pure arils,  
 oncocyclus and Regelia species and hybrids involving  
 only those two groups. “Arilbred” is the correct term for  
 any hybrid involving the bearded irises as well as arils.  
 The terminology defined above makes this explicit. One  
 might argue that “aril-median” can be taken to mean  
 a hybrid between a pure aril and a median, but this  
 does not describe the ABM irises to which the term is  
 usually applied (they are hybrids between arilbreds and  
 medians), and in any case confounds the basic premise  
 of a height-based terminology, which does not refer to  
 ancestry. 
 It is my conviction that these definitions, although  
 not without some drawbacks, represent the best  
 possible solution to the problem of classifying the  
 smaller arilbreds that can be achieved at this time.  
 They are based on a clear line of reasoning and  
 factual data about the plants themselves. The ASI has  
 included them in its proposed revision to the aril and  
 arilbred chapter of the AIS Judges Handbook, not as  
 official categories for registration and awards, but as  
 useful terminology for understanding the types and  
 variations of arilbred irises. It is hoped that hybridizers,  
 commercial growers, and the public will also find  
 these definitions helpful and embrace their use. It is  
 important that we come to a common terminology. 
 FINAL THOUGHTS 
 If the terminology proposed here is to become  
 widely accepted, it is essential that people understand  
 the philosophy and research behind these particular  
 definitions. This article is intended to explain the  
 rationale and honestly present both its virtues and its  
 shortcomings. 
 Although I believe a height-based system is best  
 suited to cope with the present realities and potential  
 future developments of the smaller arilbreds, I  
 appreciate that it will present some initial discomfort  
 for those accustomed to thinking in terms of parentage  
 alone. I draw attention back to the classification system  
 for median irises, which can produce similar discomfort
