THE ORCHID WORLD. 



The use of a proper Latin name for a 

 variety of a species is not allowed (Article II.), 

 yet for the specific name of a hybrid it is 

 permissible, the reason being that as every 

 name of a hybrid must have the sign x 

 prefixed, the hybrid nature of the plant is 

 thereby at once indicated, and effectually 

 prevents it being confused with any of the 

 species. Any other distinction, either by a 

 Latin or vulgar name, is consequently not 

 then required. 



Article IX. — " All hybrids obtained by 

 crossing the same two species must carry the 

 same specific name. All forms arising from 

 the same cross, or from successive crossings 

 of varieties of these two species, should be 

 connected as varieties, with the same specific 

 name." 



Thus all plants arising from the crossing of 

 Cattleya Bowringiana and Cattleya Schiller- 

 iana must be called x Cattleya lucida no 

 matter how they may differ. The various 

 forms will be given varietal names. 



Article X. — " When the parents of a 

 hybrid are transferred into another genus, or 

 into a new one, the name of the hybrid 

 follows, and the specific name is subject to 

 the rules of priority, or others applicable to 

 species under similar conditions, conforming 

 with Article XLVIII. of the Rules of Botanical 

 Nomenclature." 



Thus, for example, if we admit the genus 

 Paphiopedilum x Cypripedium Y erna;tianum, 

 Rchb. f. in Gard. Chron., 1888, I., p. 712 

 ( X C. Euryale Veitch. Man. Orch., iv., p. 83, 

 1889), becomes x Paphiopedilum Vernoet- 

 lanum and not P. Euryale Stein Orch., p. 4C6 

 (1892). 



Article XI. — "The names of horticultural 

 varieties of hybrids should always be 

 expressed in the vulgar tongue." 



Example : Cattleya Fabia Mane de 

 Wavrin. Cattleya Fabia Goodsonii is 

 incorrect. 



Article XII.— "Cross breeds (crosses 

 between varieties or forms of a single species) 

 and ternary hybrids or those of a higher order 

 (crosses between species of the same genus) 

 are designated by a name, or a formula, 

 following the same rules as for ordinary 



hybrids (Article VII.). For ordinary use, 

 and in the case of the offspring of well-known 

 hybrids, the formula may be omitted, and the 

 name alone serve. 



Article XIII. — " By-generic hybrids are also 

 designated by a name and a formula. The 

 generic name is formed by the combination 

 of the generic names of the parents into a 

 single word, composed as far as possible so 

 that the names of the two genera entering 

 into the composition of the hybrid are easily 

 recognisable ; it is preceded by the sign x , 

 and followed by a specific name. The specific 

 name is subject to the same rules as are those 

 of ordinary hybrids (Articles IV. and VIII.). 

 The formula is written conformably with 

 Article VII." 



The names of the two genera entering into 

 the composition of the hybrid are to be easily 

 recognisable. If this is done there seems 

 little need for the sign x . In any case, as 

 the generic name of bi- or multi-generic 

 hybrids can not possibly be anything else than 

 a hybrid, why is the sign of hybridity needed ? 



Article XIV. — " Multi-generic hybrids 

 receive a conventional generic name, preferably 

 that of a distinguished man, to which is added 

 the termination ara. A distinct generic name 

 will be formed for each different combination 

 of genera. Thus all combinations of the 

 genera Brassavola, Cattleya, Laelia, and 

 Epidendrum, no matter in what order they 

 may be intercrossed, receive the same generic 

 name which would be, for example, Linneara. 

 As an exception, the names of the tri-generic 

 hybrids Brassocaltlielia and Sophrocattlaslia, 

 already in use, are retained." 



To this should also be added Diacattlaelia. 



Article XV. — " For a new hybrid to be 

 considered as published it should be named 

 according to the rules, the formula of its par- 

 entage, and a description of the hybrid itself 

 being given. Publication is effected in the 

 same manner as with horticultural varieties 

 of species, as set out in Articles V. and VI." 



Article XVI. — " In any case, where the rules 

 of horticultural nomenclature would be 

 actually contrary to practice permitted or 

 tolerated at present, they would not have a 

 retrospective action."
