530 A Classification of Peaches and Nectarines. 



An accurate observer will distinguish other characters in 

 the glands ; they are either sessile or pedicellate, but these 

 distinctions are too minute for application on the present 

 occasion. 



The form of the glands, as well as their position, is per- 

 fectly distinct ; they are fully developed in the month of May, 

 and they continue to the last, permanent in their character, 

 and not affected by cultivation. The globose glands are 

 situated, one, two, or more on the footstalks, and one, two, or 

 more on the tips or points of the serratures of the leaves. 

 The reniform glands grow also on the footstalk of the leaves, 

 but those on the leaves are placed within the serratures, con- 

 necting, as it were, the upper and lower teeth of the serra- 

 tures together. Their leaves, when taken from a branch of 

 a vigorous growth, have more numerous glands than the 

 leaves of the globose varieties. It will however sometimes 

 happen, that glands are not discernible on some of the leaves, 

 especially on those produced from weak branches; in this 

 case other branches must be sought for which do produce 

 them. 



With regard to the flowers, on which the divisions are 

 founded, all authors previous to Duhamel have described 

 large and small flowers only. Both in the Bon Jardinier and 

 in the Pomone Francaise, " fleurs moyennes," or middle- 

 sized flowers, are mentioned ; the notice of them, however, 

 originated with Duhamel, who, in the descriptions of seve- 

 ral of his Peaches, speaks in a manner which indicates 

 even four sizes, viz. fleurs grandest fleurs assez grandest 

 fleurs petites,% fleurs tres petites,§ and on examining the
