. FIG. 153. OPENING OF LEAF-BUDS AND FLOWER-BUDS OF APPLE. 



"The burst of spring" means in large part the opening of 

 the buds. Everything was made ready the fall before. The 

 embryo shoots and flowers were tucked away, and the food 

 was stored. The warm rain falls, and the shutters open 

 and the sleepers wake : the frogs peep and the birds come. 



Arrangement of Buds. We have found that leaves are 

 usually arranged in a definite order ; buds are borne in the 

 axils of leaves : therefore buds must exhibit phyllotaxy.
