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
A new and distinct cultivar of cherry tree useful as a dwarfing, small-leaved cherry rootstock substantially as shown and described, discovered in De Belder Nursery, Kalmthout, Belgium, growing among a population of Prunus canescens, which, when used as an understock, induces less growth of the cherry tree, is graft-compatible with most commercial cultivars of sweet cherry trees, and provides increased fruit production of the early life of the grafted cherry tree.
