NECTARINES. 309 



are now acquainted with ; the others will remain to be 

 filled up as new kinds arise, there being at present no 

 plants with such characters. 



The practice which has lately prevailed, and which I 

 hope will be continued, of obtaining new varieties by 

 cross impregnation ; the glandless with the glandular, 

 the large-flowered with the small-flowered, Peaches with 

 Nectarines, and the Pavies with the Melting kinds, is 

 the method by which the completion of the arrange- 

 ment, as well as the extension of good sorts, is the most 

 likely to be accomplished ; but in pursuing this method, 

 it should not be forgotten that the most excellent of 

 each kind are those only which ought to be employed. 



The fruits which I have now arranged under the 

 different sections are those, both French and English, 

 which have been described by different authors ; some 

 others are added, which are well known in England, 

 but which have not been noticed in any work of cele- 

 brity. 



In the following Tables, the classes are founded on 

 the leaves, and the divisions on the flowers. 



CLASS I. 



Contains those whose leaves are deeply and doubly 

 serrated, having no glands. 



CLASS 2. 



Those whose leaves are crenate or serrulate, having 

 globose glands. 



CLASS 3. 



Those whose leaves are crenate or serrulate, having 

 reniform glands. 



An accurate observer will distinguish other characters 

 in the glands ; they are either sessile or pedicellate ; but
