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
The subject of the present disclosure is a new and distinct variety of miniature rose plant characterized by the bright yellow buds and flowers which become overlaid or blended with red as they mature and by the profusion of bloom.
