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.

I claim: 1. A new and distinct variety of Amelanchier×grandiflora substantially as herein shown and described, characterized by denser branching pattern so as not to be subject to winter ice damage, and no summer leaf drop due to fungus disease, and the consistent bright red fall color with a majority of the leaves turning at substantially the same time.
