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 dwarf bush rose of the hybrid miniature moss rose class. The plant has many moss-scented stipitate glands on its penduncles, buds, sepals and hips, and blooms almost continuously throughout the growing season. The overall color effect of the flowers is a deep velvety red. There are from about 40 to about 50 relatively broad petals in the flower, with from 7 to 20 petaloids. The plant manifests a better-than-average resistance to mildew, as compared to roses of its class under parallel conditions.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
I claim: 1. A new variety of bush rose of the hybrid miniature moss class, substantially as illustrated and described herein, being particularly characterized by a combination of features including the bearing of many moss-scented stipitate glands on its peduncles, buds, sepals and hips; by the coloration of its flowers, which are of a deep velvety red color, and open relatively slowly with a high pointed center; the petalage of its blooms, which have from about 40 to about 50 petals plus about 7 to 20 petaloids; and the tendency to bloom throughout the growing season.
