Which of these systems is to be preferred, or can a better one be 

 devised ? 

 Reply. — 



The following Eules are quoted from our Sub-Committee's 

 recommendations (see Jour. E.H.S. " xxxvi. (1910) p. 407). 



Rule 4. — Future multigeneric hybrids (combining three or 

 more genera) should be given a conventional generic name consist- 

 ing of the name of some person eminent as a student or as a grower 

 of orchids, followed by the termination *ara.' 



Rule 5. — A separate generic name should be coined for each 

 distinct combination of genera. Thus: — 



Brassocattleya x Epilaelia, and 

 Brassodendrum x Brassocattleya, and 

 Brassolaelia x Epicattleya, and 

 Brassolaelia x Epidendrum, 



and all. other possible combinations of those four genera would be 

 designated by one name, e.g. Adamara, while a second generic name, 

 e.g. Lhineara, would need to be coined for Dialaelia x Brasso- 

 cattleya, and this would stand for all combinations of the four genera 

 Diacrium, Laelia, Brassavola, and Cattleya. 



18. Publication of hybrids. 



In order for a new hybrid to be considered published is it to be 

 recommended that the same rules should apply as for the valid publica- 

 tion of varieties of true species (see Question 5) ; or would it be 

 sufficient, for example, to give a name and a formula^ — that is, to make 

 known the parentage? 



Reply. — 



The publication of the names of hybrids should be governed 

 by precisely the same rules as those of varieties under Section 5. 



19. Are there any other details relative to horticultural nomencla- 

 ture which it would be useful to discuss at the Congress? 



20. In horticultural catalogues it frequently happens that the same 

 plant is found under two or more names, which are only synonyms. 

 Certain catalogues also are full of orthographical errors. 



Would it not be useful to publish an Index of all the species which 

 have been introduced into cultivation giving their correct names as 

 much with a view to nomenclature as to orthography, with their 

 synonymy ? This would serve as a guide to the compilers of catalogues 

 and in correct labelling, and would prevent buyers being misled. 



If an Index is considered desirable, what other information should 

 it contain besides the names? 



Reply. — 



Such an index would be infinitely useful. The name of the 

 species or variety according to the above rules, with its place and 

 date of publication, and where possible a reference to a good figure, 

 with indication of synonymy would be required. A ' splitter's ' point 

 of view of species should be adopted.
