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
This chrysanthemum cultivar originated as a sport of the variety "Hartmann's Dignity" (U.S. Plant Pat. No. 4,377) and is distinguished by the pleasing light yellow color of its large composite and incurved standard blooms. Otherwise this new plant is about the same in its growth and blooming habits as the parent variety.
