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 poinsettia plant is a sport of Ott Poinsettia (U.S. Plant Pat. No. 4,310). The new variety is characterized by an upper layer of lobed bracts which stand out with more erectness and less droop than on the parent. The leaves also stand out with more erectness and less droop than on the parent.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
What is claimed is: 1. A new and distinct variety of poinsettia plant, substantially as herein illustrated and described, characterized particularly as to novelty by having from three to six lobed bracts in the uppermost layer of bracts, the stems of these lobed bracts originating on the dark-green plant stem from locations below the light-green flower stem, the stems of these lobed bracts projecting diagonally upwardly through a layer of non-lobed bracts which project outwardly from the light-green flower stem, the bracts and the leaves standing out more erectly and not drooping as much as on the parent or other preceding Annette Hegg variety, the bracts being wide and long and densely spaced.
