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 invention relates to a new and distinct variety of New Guinea Impatiens plant known by the cultivar name Cheyenne, and discovered by me in commercial greenhouses in Fremont, Calif. Cheyenne isn't close to any of the varieties presently on the market. Cheyenne is particularly characterized by dark green foliage with a tint of red (adding to the darkness of the foliage); very floriferous; a medium bright red flower with a distinctive light eye; different color breaks (as many as 6) on the flowers with the three most common ones being rose-red, flecked red on white and orange; and an upright growth habit with moderate stem size.
