Kraft in his Pomona Austriaca, 1796, described a Weisse Kaiserpflaume 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.
