Tills limited data, supplemented by a large mass of un- 

 recorded observation, leads me to believe that our improved 

 varieties ol the cherry are subject to partial sterility, which seems 

 to be corelated with quality. 



Citron. Citrus medica, L. (Rutac"/E). 



This is a large oblong or ovate fruit, the skin rough with pro- 

 tuberances, and of the well known citron color when ripe. There 

 are very many varieties, some round, some oval, others oblate 

 spherical, and others fingered. Very many fingered forms are fig- 

 ured by the early writers. It is a pulpy fruit with a spongy 

 rind. It is supposed by many botanists that the citron, the 

 orange, the lemon, and the lime, are all derived from this species', 

 Brandis and Sir Joseph Hooker distinguished four cultivated 

 varieties: Cz'tnts medica, the Ccdratier of the French, the Citron 

 of the English, the Cedro of the Italians, called Vijapitra in Sans- 

 crit; Citrus medica Limonnm, the Citrionnier of the French, the 

 Lemon of the English; Citrus medica acida {C acida, Roxb.). 

 called in Sanscrit Jambira ; Citrus medica Limetta {C Livietta 

 and C Luniia, Risso), the Sweet Lime.'' 



The Chinese citron, the cedrat of Florence, and several others
