Identification of Individual Stud Plants. 



The practical consequences of these first principles are important 

 and far-reaching from the Orchid breeder's point of view. 



If each individual plant grown from a seed has a definite germinal 

 constitution which determines its breeding powers and potentialities, 

 then it is necessary that each individual plant used as a parent should 

 have an identification mark. Whether this identification mark consists 

 of an individual name, a stud number, or anything else is simply a matter 

 of convenience, sO' long as the identity of each stud individual is main- 

 tained for future use. In 1909 the writer suggested that identifica- 

 tion might be assured by putting the name of the importer or raiser 

 in brackets after the ordinary name together with a number showing 

 the order of its appearance — e.g., Gypripedium callosmm Sanilerae 

 [Sander I.] , [Low I.] , [Gookson I.] , [Statter I.] , and so forth. The 

 first was imported in 1894, the second in 1904, and the third and fourth 

 were raised by hand presumably from the first. All divisions of the 

 original plant, as a rule, may be expected to have the same germinal 

 constitution, and would consequently bear the same identification mark. 



There is no doubt that in course of time certain individual plants 

 would acquire a stud reputation much in the same way as a noted sire 

 or brood mare does in thorough-bred horses, and the propagation of 

 such an individual Orchid by division and its distribution would become 

 a "valuable economic asset.
