or feparately, as in apple and pear-trees. Other flower-buds arife from 

 the (hoots of the prefent year alternately with leaf-buds, as thofe of 

 vines, and form the third or fourth buds of the new fhoots. 



Th

differ from leaf-buds in this circumflance, that they perifh when th 

 feeds are ripe^ without producing any addition or increafe to the tree 

 whereas when the leaf-buds perifh in the autumn, their caudexes, th{

leaf-buds fhoot forth their caudexes and radicles, or infert them into 



it, and gradually fabricate the new bark and root-fibres.. 



It was before mentioned, that it is believed by fome difclplesof the
