WHY CERTAIN VARIETIES DO NOT SET FREELY. 59 



Fig. 22& represents the " imperfect hermaphrodite " flower which 

 we have observed in the following varieties : Alnwick Seedling, 

 Black Morocco, Chaouch, Diamant Traube, Eldorado, Lady. These 

 varieties do not, as a fact, set freely ; and this is, probably, owing to 

 the deflexed stamens not being near enough to the stigma for it to 

 receive the pollen, these apparently not being affected by the jerk in 

 the dislodgement of the cap to so great an extent as the others. 



It would thus appear that the defect of setting in some instances 

 is a structural or constitutional peculiarity, not influenced to any great 

 extent by the cultivator's skill. Artificial impregnation is the only 

 legitimate remedy or practice to follow. 



The illustration here given, fig. 23, is that of a small bunch of the 

 Black Morocco, in which it will be seen that only two or three berries 

 have been properly set, and have continued to grow ; the small berries 

 never growing larger, although they ripen, and are very sweet, 

 in this respect exactly resembling those varieties which are termed 

 " stoneless " Grapes, such as the Black Monukka, Corinth, Sultana, 

 etc., which rarely produce any perfect berries, although they have 

 erect stamens.
