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 as a seedling among seedlings produced by open-pollination of offspring of a Prunus dawyckensis mother tree found growing in De Belder Nursery, Kalmthout, Belgium, which, when used as an understock, for sweet cherry trees, induces less growth of the sweet cherry tree, a semi-erect growth habit, a light canopy and early and abundant flowering and fruit setting.
