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 hybrid tea class rose plant having novel, very bright yellow flowers that are tipped in red, the red intensifying and spreading across the upper side of the petal as it ages, smooth rachises with many glands at their bases, smooth stipules having edges with many glands, and thick leathery petals.
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 rose plant of the hybrid tea class, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of its unique bright yellow flower color that is tipped in red, the gradual spread of this red coloration across the whole flower petal upper surface as it ages while the reverse of the petal stays yellow unless exposed to the sun, and the presence of many glands on the otherwise smooth stipule edges and on the bases of the rachises.
