2. of a new variety exhibited at a Show and 



(a) mentioned ; 



(b) not mentioned in the periodical reviews ; 



3. or shall other modes of publication be permitted? 

 Reply.- — 



The publication of a name of a horticultural variety or hybrid, etc., 

 is by 



1. (a) the description of the form, with or without a figure in 

 the recognized horticultural periodicals or publications of scientific 

 societies of any country, and 



1. (b) by the publication with an adequate description in the 

 catalogue of a nurseryman, and 



2. (a) by the exhibition and subsequent description in the report 

 of a horticultural meeting, or the description in the report of official 

 trials of horticultural varieties, but 



2. (h) the mere exhibition of a variety without its subsequent 

 description shall not be regarded as valid publication. 



3. No other mode of publication shall be recognized. 

 Recommendation. — All friends of horticultural progress will take 



care that adequate descriptions of forms appear in the horticultural 

 periodicals and are not buried in nurserymen's catalogues. 



6. Nom. Bot. Art. 39. — " The date of a name or of a combination 

 of names is that of their effective publication. In the absence of 

 proof to the contrary, the date placed on the work containing the 

 name or combination of names is regarded as correct. After Janu- 

 ary 1, 1908, the date of the publication of the Latm diagnosis only 

 can be taken into account in questions of priority." 



Is it desirable to maintain the necessity for a Latin diagnosis for the 

 valid publication of a horticultural variety ? 



Or should the publication of the characters be made in one of the 

 most commonly spoken languages, or if in one language only, in which? 



Reply. — 



The date of effective publication of a name is the date upon 

 which the article containing the name and description was issued to 

 the public. The Art. 39 so far as it applies to the date is agreed to, 

 but the exigence of the Latin diagnosis should not be maintained ; 

 the description is admissible in any language whatever. 

 Recommendation. — It would, however, be very greatly to the advan- 

 tage of the horticultural world if the description were published in 

 English, French, German, Italian, or Spanish. 



7. Hybrids between Species of the same Genus. — Noin. Bot. 

 Art. 31. — " Hybrids between species of the same genus, or presumably

 sary, a name.
