Kraft in his Pomona Austriaca, 1796, described a Weisse Kaiser- 

 pflaume and a Weisse Kaiserinnpflaume and gave Imperatrice Blanche 

 as a synonym to both of them. The latter he gave as a variety of the 

 Weisse Kaiserpflaume but it is probable that they are the same since no 

 other author noted the distinction, and, in fact, the differences mentioned 

 are wholly insignificant. According to Downing this variety was little 

 known in this country in 1845 and it is doubtful if it is now known at all. 

 It is described as follows: 



Compared with the Saint Catherine, which it resembles, it is found to differ in that 

 its stone is free and its flavor less high; branches smooth; leaves smaller and less shining; 

 fruit matures in September; of medium size, obovate; suture indistinct ; cavity narrow; 

 skin yellow, spotted with a little red; bloom thin; flesh yellow, crisp, juicy, sweet.

White Perdrigon is an old French variety grown extensively in the 

 vicinity of Brignoles, France where it is used in the manufacture of the 

 famous Brignoles Prunes. Because of its use for this purpose, it has been 

 badly confused with a similar variety, the Brignole, which derived its name 

 from the town of Brignoles, where it was first grown. The variety is pro- 

 bably not known in America and might be worth introducing. It is des- 

 cribed as follows:
