HORTICULTUEAL NOMENCLATURE.

whicli from the point of view of pure botany are of very secondary 

 importance, are exceedingly important from the horticultm'ist's point 

 of view, and these may not have been treated in the " Eules " in 

 a sufficiently 'complete manner:. This applies particularly to the 

 nomenclature of horticultural varieties and to the nomenclature of 

 hybrids. The nomenclature of artificial hybrids, now so important in 

 the garden, appears scarcely to have been touched upon. 



■ Should the Eules elaborated at the Vienna Botanical Congress be 

 adopted for horticultural use, with the additions necessary to make them 

 apply to horticultural varieties and hybrids ? 

 Society's Reply. — 



The Eoyal Horticultural Society of London considers it essential 

 that the rules adopted by the Botanical Congress of Vienna, 1905, 

 so far as they apply to names of species and to groups of a higher 

 order, should be strictly binding upon horticulturists ; but they 

 agree that the articles dealing with horticultural varieties and with 

 ■ hybrids of cultivated plants, require to be supplemented in order to 

 meet numerous cases not now provided for. 



Further, they consider that the same principles which apply to 

 the names of larger groups should apply equally to the names of 

 these, and that in any code of rules for the guidance of horticulturists 

 these principles should be incorporated. 



2. Nomenclature of Varieties of Species. — Regies de nomenclature 

 hotanique. Art. 30. — " Forms and half-breeds among cultivated 

 plants should receive fancy names, in the common language, as dif- 

 ferent as possible from the Latin names of species or varieties. When 

 they can be traced back to a species, a sub-species or a botanical 

 variety, this is indicated by a succession of names." 



[Example: Pelargonium zonale 'Mrs. Pollock.'] 



Note that Latin is proscribed for names of the plants referred to. 



Is it desirable to modify or amplify this article? 

 Reply. — 



Art. 30 should be modified so that Latin names for horticultural 

 varieties are not proscribed. It might read : — 

 " Forms of and crosses among cultivated plants should receive 

 names which should follow those of the species, sub-species, or 

 botanical variety from which they have been derived." 

 The article should be followed by recommendations : — 



I. Names of Latin form should be restricted to forms of plants 

 which are not recognized as " florists' flowers." 



E.g. Alyssum maritvmum 7ianum. 

 Ilex aquifolium Foxii. 

 Saxifraga granulata flore pleno. 



r 2. Forms of " florists' flowers " and vegetables should receive 

 fancy names or names in the vulgar tongue. Where they can be traced 

 back to a species they should follow^ the name of the species, but 

 where they are derived from the crossing of several species India-
