82 TREATISE ON FRUIT TREES. 



Its pit is large, flat, very rough, ten-&-a-half lignes long, eight lignes wide, and 

 four lignes thick. 



This plum ripens toward the end of July. It's an extremely good fruit. If it hasn't 

 completely ripened on the tree, or if the tree hasn't been planted in a good exposure, the 

 skin is quite light red & not purple. 



XVIII. PLUM TREE with very large round pale purple fruit. 

 Cyprus PLUM. 



This plum is very big, almost round, nineteen lignes high by nineteen-&-a-half 

 lignes in diameter. An almost imperceptible groove divides it lengthwise. It terminates in 

 a small indentation at the top & in another much larger one at the other end where the 

 stalk inserts at the center. The stalk is thick and seven lignes long. 



Its skin is light purple, covered with bloom, tough, and has a very tart taste. It's 

 extremely difficult to separate it from the flesh. 



Its flesh is green and firm. 



The juice is quite plentiful & sugary. But it has a tartness & an unpleasant wild 

 taste. However, when the fruit is extremely ripe, its flesh becomes tender, the juice loses 

 its tartness, & then it's quite good. 



The pit isn't large in proportion to the fruit. It clings to the flesh only at one or two 

 spots. It's very rough & one of its edges is raised with very prominent ridges.

 Swiss PLUM. (PL XX. Fig. 7.)
