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.
