THE TEACH AND NECTARINE. 129 



the serratures, connecting, as it were, the upper 

 and lower teeth of the serratures together ; their 

 leaves, when taken from a branch of a vigorous 

 growth, have more 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 on weak 

 branches ; in this case, other branches must be 

 sought for which do produce them." 



These classes, thus formed, are each divided into 

 three divisions. 



Div. I, embraces those which produce large flow- 

 ers. 



Div. II, includes those which produce flowers 

 of medium size. 



Div. Ill, contains those which produce small 

 flowers. 



These divisions are not so distinctly marked as 

 the classes ; the middle and small flowers only dif- 

 fering by the former being larger in all their parts. 



The sub-divisions, two in number, are determined 

 by the fruit. The first comprehends true peaches, 

 or those which have a downy skin ; the second in- 

 cludes nectarines, or those which have a smooth 

 skin, similar to that of the plum. 



Each of these sub-divisions are again divided into 

 two sections; the former including the pavies or 

 clingstones; the law**, the metiers or free-stones. 



The following sy*<*f lical table will exhibit these
