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 variety of Butternut tree (i.e. Juglans cinerea) is provided which originated as a chance seedling among seedlings produced from seed planted in a cultivated area. The new variety is of unknown parentage and readily can be distinguished by its ability to form large quantities of nuts which are frequently borne in clusters of five or more. Unlike nuts commonly formed on Butternut trees, the nuts of the present variety have the ability to readily separate from the hull. Additionally, the trees of the present variety exhibit good winter hardiness and resistance to the Witches'-Broom disease which commonly afflicts Butternut trees.
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 Juglans cinerea, substantially as illustrated and described, characterized by (a) the formation of a large tree of medium vigor, (b) extremely high nut productivity wherein average sized nuts are frequently borne in clusters of approximately five or more, (c) the propensity for the nuts to readily separate from the hull when opened, (d) the formation of buds which exhibit good winter hardiness, (e) the formation of flowers which exhibit good resistance to frost, (f) the relative absence of damage by casebearer insects, and (g) resistance to Witches'-Broom disease.
