Production of Double Flowers 491 



cates a distinct plan, and the possibility of 

 carrying it to a practical conclusion within a 

 few years' time. 



Something more is known about other cases. 

 Garden anemones, Anemone coronaria, are said 

 to have become double ia the first half of the 

 last century in an English nursery. The owner, 

 Williamson, observing in his beds a flower with 

 a single broadened stamen, saved its seeds sep- 

 arately, and in the next generations procured 

 beautifully filled flowers. These he afterwards 

 had crossed by bees with a number of colored 

 varieties, and in this way succeeded ia produc- 

 ing many new double types of anemone. 



The first double petunia is known to have sud- 

 denly and accidentally arisen from ordinary 

 seed in a private garden at Lyons about 1855. 

 From this one plant all double races and varie- 

 ties have been derived by natural and partly by 

 artificial crosses. Carriere, who reported this 

 fact, added that likewise other species were 

 known at that time to produce new double varie- 

 ties rapidly. The double fuchsias originated 

 about the same time (1854) and ten years later 

 the range of double varieties of this plant had 

 become so large that Carriere found it impos- 

 sible to enumerate all of them. 



Double carnations seem to be relatively old, 

 double corn-flowers and double blue-bells being
