the hybrid is of known experimental origin the formula may be made 

 more precise by the addition of the signs and $ . 



The name, which is subject to the same rules as the names of 

 species, is distinguished from the latter by absence of an ordinal number 

 and by the sign x before the name." 



Example : X Caitleya Brahaniiae (C. Aclandiae 3 x C. Loddi- ' 

 gesii $ ). 



Frequently the sign x is placed before the specific name : Cattleya 

 xBrahantiae (C. Aclandiae x C. Loddigesii). 



Sometimes the sign x is omitted : Cattleya Brahantiae (C. Aclan- ! 

 diae x G. Loddigesii). 



Which of these three methods of writing the name is to be recom- 

 mended, or should the matter remain optional? j 



Reply. — 



The name of an undoubted hybrid between species of the same 

 genus should have the sign of hybridity between its 'generic and 

 specific names, otherwise the nomenclature should follow Art. 31 

 of the " Eules of Nomenclature." 



'8. In what language should the specific nam.e of a hybrid be 

 expressed? 



Most authors express the specific name of hybrids either in Latin 

 or in some generally familiar language. Others consider this name 

 should be in Latin; thus, Messrs. Eolfe and Hurst (" Orchid Stud- 

 book," 1909) translate into Latin all specific names expressed in other 

 languages. 



Example : Cattleya x ' Princesse Clementine ' becomes in their 

 work C. X Clementinae. . , | 



Reply.— 



lire specific name of such hybrids should be of the Latin form. , r 



9. Should the specific name of a hybrid be expressed as a single j 

 word, or may it contain more words? 



Certain authors, as Messrs. Eolfe and Hurst (" Orclfid Stud- ; 

 Book "), invariably adopt only one word, even when the name wasi; 

 published in Latin. j 



Example : Cattleya Memoria Bleui becomes according to themj 

 C. X Bleui. j 



Reply.— I 

 These specific names should consist of a single word. 



10. If the specific names of hybrids are to be expressed in thej 

 vulgar tongue, should names consisting of three, four, five, or some-j 

 times more words be perzuitted ? . |
