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 variety of hybrid miniature moss rose, bearing many moss-scented stipitate glands on its stems, peduncles, buds and sepals. The plant grows vigorously, is hardy, and blooms almost continuously throughout the growing season. It is fairly large, in comparison to roses of the miniature class generally. Its blooms are medium pink in color, and have very double petalage, with from 25 to 60 petals and from 1 to 8 petaloids. It has viable pollen and will set hips when grown under greenhouse conditions. It has a better-than-average resistance to mildew, as compared to other roses of its class, grown under parallel conditions.
