No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new and distinct variety of plum tree, substantially as illustrated and described, particularly characterized by the regular and very productive bearing of semi-freestone fruit which ripens about with, and most nearly resembles, the fruit of the Eldorado, but, in comparative distinction, the globose fruit of the present variety has red flesh, whereas the oblate fruit of the Eldorado has yellow flesh.
