7. An embryon bud, therefore, whether it be a leaf-bud or a flower- 

 bud is the viviparous offspring of an adult leaf-bud, and is as indivi- 

 dual as a feed, which is its oviparous offspring. It coniifts, firft, of 

 a central oro-anization or caudex like the corculum of a feed, which 



f 



abforbent vefTels, and elands 



o 



contains the rudiments of arteries, vein 

 with an internal pith or brain. 



Secondly, it is furniflied with a fyftem of umbilical vefl^els, which 

 are inferted into the alburnum or fap-wood of the tree, or form a part 

 of it, and defcending into the earth fupply it in the early fpring with 



roots, fo called, which pafs from 



firft nutrition, like the femina

Thirdly, this umbilical fyftem probably contains alfo what may be 

 termed a placental artery, terminating on the coats of the lateral air- 

 veflels, which penetrate the bark of trees horizontally, for the pur- 



pofe of oxygenating the 



tributed from the umbilical veflels of the chick on the air-bag at the 



blood of the vegetable fetus, like thofe dif^ 



broad end of the egg. SeeSed. II. 4. and III. i

Fourthly, it contains the rudiments of organs adapted to lateral ge- 

 leration or the produdion of new buds ; or to fexual propagation 

 nd the confequent produdion of feeds. 



In the early fpring the umbilical veiTels fupply the embryon bud 



of trees with fap-juicje, which is then feen to exfude from wounds of
