No cultivar name of record

This patent does not name the plant, and for its era that is ordinary rather than an omission. Before about 1980, breeders frequently patented a plant without giving it a cultivar name at all — the grant identified it by its number, its parentage and a written description of the flower and foliage. Most plant patents from the 1930s to the 1970s have no name in them.

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 is characterized by a flower having generally the same characteristics as its parent, Annette Hegg Supreme (U.S. Plant Pat. No. 3,392) but the new variety is a brighter darker red and under normal growing conditions the bracts are between 10 percent and 40 percent wider with less open space between bracts. The new plant is 10-20 percent shorter than its parent and is more compact. The new plant blooms 3-5 days earlier than its parent. The new variety is a self branching plant. When pinched, the sprouts finish more uniformly than the parent. Leaf and bract retentions are equal to those of 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 a color which is bright red but a darker red than its parent, Annette Hegg Supreme (U.S. Plant Pat. No. 3,392), its grandparent, Annette Hegg (U.S. Plant Pat. No. 2,962), and related sports which have evolved directly or indirectly from said grandparent, bracts which are between 10 and 40% wider than in the parent Annette Hegg Supreme, thereby providing less open space between bracts, a plant which is approximately 10-20 percent shorter and is more compact than its parent, Annette Hegg Supreme, its grandparent, Annette Hegg, and sports thereof, a plant which grows more uniformly than does the parent, Annette Hegg Supreme, a plant which blooms 3-5 days earlier than its parent and its grandparent, and a plant which has good leaf and bract retentions equal to that of the parent.
