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 novel begonia originated as a mutation of Ballerina, and has bright yellow tepals.
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 cultivar of begonia plant characterized particularly as to uniqueness by the combined characteristics of bright yellow double flowers having a size up to 6 cm. in diameter when mature, with the flowers having an odd number of tepals; very fast growing habit which requires growth regulation for height control in high light and high temperature conditions, and long lasting nature of the individual flowers.
