Let us suppose that a nurseryman, park superintendent, or amateur gardener has just flowered a batch of seedlings of, say, _Helenium_, and that he spots one as being of a new type and worthy of propagation. In due course he shows the plant at a fortnightly show, under a number, and an Award of Merit is given to it. He must now find a cultivar-name for his new plant. His first problem, of course, is to choose a name that has not been used before in the genus _Helenium_. If he picks on a very unusual personal name he can be fairly certain that he is the first to use it. If, however, he prefers a more general name, like 'Innocence' or 'Venus,' there is a danger that it has been used before. If there existed a registration authority for _Helenium_ names, as there does, for example, for names of Daffodils, he could, of course, consult this authority, but in its absence he must do his best to comb the likely literature--for example the Index to this JOURNAL, nurserymen's catalogues, etc.--and to assure himself that his chosen name has not already been used. His next step is to make certain that the name is in accordance with the best practice for coining such names. Here is where the Code will help him. In it he will find (under Section F) a series of rules for his guidance, based on the accumulated experience of horticulturists of many nations. I will not repeat these rules here--they can be read in the Code--but perhaps the most important, apart from the rule already quoted that the name must not be in Latin, is that it should be short (not more than two words), should avoid forms of address liable to be confused (_e.g._ Mr., Mrs. and Miss) and, as far as possible, should be easily pronounceable by all nationalities. As the Code says, 'Centenaire de Rozain-Bourcharlat,' 'Diplomagartenbauinspektor,' and 'Eldwyth Cholmondeley' are not looked upon with favour as cultivar-names! Having chosen a name, it is essential to ensure that it is published, together with an adequate description, since the Code does not recognize names that are not published, or are published with no description. The Code lays down what is meant by publication, and by adequate description. The names of plants which receive an Award at Vincent Square are automatically published, with a description, in this JOURNAL, but for other methods of publication the Code should be consulted. _Hybrids_
