 fragrant callas in existence to-day are all the 

 descendants, through the process of division, of 

 the original second generation seedling. 



This new race of callas was named the 

 "Fragrance." 



Fortunately it chanced to combine with the 

 habit of perfume production the habit of abundant 

 and constant blooming. Indeed, in this regard 

 it probably excels all other varieties of calla. 

 THE NEW CALLA A "SPORT" 



It thus appears that the perfumed calla was 

 developed through selection and in the short 

 period of two generations, from a perfumed 

 individual that appeared "spontaneously" among 

 some thousands of odorless seedlings. 



Using a term that is peculiarly popular in 

 recent years, we might say that so marked a 

 variation from the normal or usual form of calla

In the size and color and general appearance 

 of its flower, as well as of its entire structure, 

 the new calla precisely resembled its fellows. Yet 

 we are surely justified in speaking of so very

 perfume as constituting an important departure 

 from the normal. 



No one knows precisely what the chemical
