THE CHERRY ] 369 



Most of the butterflies, moths, and beetles which 

 attack the plum in continental Europe are also common 

 to the apricot, but in our orchards the only beetle which 

 is sometimes met with on the stems and branches of 

 weakly apricot trees is Bostrychus dispar Fb., but 

 apricot trees grafted on plum-stock often succumb to the 

 insidious attacks of the beetle (Japnodts tenebrionis L., 

 whose larvae live, often in numerous colonies, on the 

 tender tissues between the bark and the wood, of the 

 stem and of the large superficial roots. 



THE CHERRY. 



The following classification will explain the relation- 

 ship which exists between the various types of cultivated 

 cherries and of the stock on which they are grown. 



i. Primus Ai'ium Lin. Cerasus Avium Moench. 

 C. nigra Mill C. dulcis Borkh. ( French. =-cerisier 

 merisier. \\.3\\-d3\ciliegio. Maltese^ h'nwtf); This is 

 the Wild Cherry or Gean tree, native of Europe and 

 Western Asia. It is a tall tree sometimes exceeding 15 

 metres in height, and never or rarely throws up any 

 suckers, producing flowers in umbelliform clusters a short 

 time before the leaves or along with them. The branches 

 are thick and erect. The leaves are rather long, acu 

 minate, doubly serrated, united in clusters at the 

 extremity of the twigs. The flowers are white, on long 

 stalks. The fruit is pendulous, ovoid or heart-shaped, 

 and the flesh is rather firm, sweet and adheres to the 

 stone. The species includes the following varieties or 

 forms. 



I. TYPICA, in which the fruit is roundish or ovate, 

 with a very juicy pulp.
