de:scription of varie:ties 



The following list contains not only those varieties of local origin which 

 have been named up to the present time but is a complete list of all the 

 named varieties in cultivation of which it has been possible to obtain de- 

 scriptions. 



With the increasing number of varieties being propagated every year, it 

 will be absolutely essential to any exact knowledge of this subject that the 

 introducer of any variety shows sufficient differences between the new variety 

 and all previously known ones to warrant giving it a name.
