614 Mutations 



specimen near Orleans by Mme LeBrun in a 

 large culture of Mahaleh. Lonicera tatar- 

 ica nana appeared in 1825 at Fontenay-aux- 

 Roses. A tall variety of the strawberry is 

 called " Giant of Zuidwijk ^' and originated at 

 Boskoop in Holland in the nursery of Mr. van 

 de AVater, in a lot of seedlings of the ordinary 

 strawberry. It was very large, but produced 

 few runners, and was propagated with much dif- 

 ficulty, for after six years only 15 plants were 

 available. It proved to be a late variety with 

 abundant large fruit, and was sold at a high 

 price. For a long time it was prominent in 

 cultures in Holland only. 



Varieties without prickles are known to have 

 originated all of a sudden in sundry cases. 

 Gleditschia sinensis, introduced in 1774 from 

 China, gave two seedlings without spines in the 

 year 1823, in the nursery of Caumzet. It is 

 curious in being one of the rare instances where 

 a simultaneous mutation in two specimens is 

 acknowledged, because as a rule, such records 

 comply with the prevailing, though inexact, be- 

 lief that horticultural mutations always appear 

 in single individuals. 



From Korshinsky's survey of varieties with 

 cut leaves or laciniate forms the following cases 

 may be quoted. In the year 1830 a nurseryman 

 named Jacques had sown a large lot of elms.
