Perhaps the most important section of the whole Code deals with the _Registration_ of cultivar-names. In certain groups (_e.g._ Daffodils) international registration schemes already exist, and it is urged that further schemes, covering all important groups of cultivated plants, should be established as soon as possible. The function of such authorities would consist, primarily, of (1) registering new names and ensuring that they are in accordance with the Code, and (2) preparing, and keeping up to date, lists of cultivars in their groups. In addition, the authorities would choose a particular publication as the "starting-point" of the nomenclature in the group (so as to avoid dipping too deeply into the past in search of ever earlier cultivar-names), and would act as arbiters when a decision has to be made between two or more widely used names for the same cultivar. There is no doubt in the minds of those responsible for the Code that the existence of internationally trusted and respected registration authorities would do more than anything else to stabilize and simplify the naming of cultivated plants. It will obviously take some time before authorities can be set up for all--or even the majority--of important groups, but the International Committee is doing its best to push ahead quickly with this very important side of their work. At the end of the Code there are sections dealing with certain special categories such as re-selected and improved cultivars, con-varieties, clones, apomicts and line-hybrids, which are of interest mainly to specialists in breeding and taxonomic work on cultivated plants. I hope I have said enough, in this short article, to convince readers of the JOURNAL that the Code is of some interest to them if they want to use the names of plants so that other gardeners, both here and abroad can understand what they mean. The next step is to read the Code itself--first the Summary and then the full text that follows it. No doubt many who do so will be put off at first by the somewhat legal language used. One can only repeat the time-honoured defence by lawyers when similarly attacked--that to avoid ambiguity experience has shown that a certain amount of jargon is necessary! We have tried hard, in the Code, to keep it to a minimum. The International Committee is anxious to receive suggestions for improving the Code, so that they can be discussed at the next Horticultural Congress. All such suggestions should be sent to the Secretary of the Committee (DR. H. R. FLETCHER), c/o The Royal Horticultural Society, Vincent Square, London, S.W.1.
