 aiice. For instance, the albino Paphiopedilum callomni Sandcrac was 

 first flowered from an importation of Messrs. Sander in 1894, and tbis 

 plant (and its many offshoots) might be called (Sander 1). Another 

 individual of this albino appeared in an importation of Messrs. Low 

 in 1904, and might be called (Low 1), and so on. 



The hand-raised seedlings of these albinos might be similarly dis- 

 tinguished, thus (Cookson 1), (Staffer 1), and so on. 



In this way all the individuals of any particular albino could be 

 distinguished for stud purposes. The same principle might be adopted

for special individual coloured forms, and indeed for garden plants 

 generally, to the great advantage of breeders and growers. Standard 

 stud individuals of known germinal constitution would then have a 

 definite value, and their propagation and distribution would be more 

 profitable to all concerned. Once the genetic properties of the in- 

 dividual plant are ascertained, all future breeding results from that 

 plant (and its distributed offshoots) could be foreseen by the aid of 

 Mendel's law. 



Mendet.ism and the Seed Grower. 



To none will the consequences of Mendelism appeal more strongly 

 than to the professionaf seed grower. The prosperity — nay, the very 

 existence — of his business depends on growing true stocks of seed.
