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.
Abstract
Disclosed is a new and distinct variety of plum tree characterized in its comparison with the Nubiana plum which it most nearly resembles but is an improvement thereon in ripening much earlier, between May 14 and May 21, is slightly more oblate and compressed in shape, has a more attractive dark maroon to almost black skin color when ripe, and a richer, vinuous flavor. The instant variety also ripens more than one week earlier than the Red Beaut (patented) which is the conventional earliest plum variety.
