Application  on  2 Jun 1941
The parentage of the rose bush is not exactly known but was produced through cross-polleniza- tion of several varieties or classes of roses, among which were the common variety of Cecil Brunner rose, and a rose bush produced by cross-polleniza- tion and which is similar to the "'World's Fair," but whose parentage is not now known, and is an unnamed rose. The particular rose illustrated is a second generation cross-pollenization of one of the rose bushes resulting from the aforesaid cross-pollenization and further cross-pollenized with the common variety of Cecil Brunner rose.
Notes:
The discussion of parentage in the patent is rather complicated, but the parentage is not. Apparently this rose resulted from this cross: (open-pollinated seedling of a red rose) x 'Cecile Brunner'. (The red rose was derived from 'Cecile Brunner', and was the male parent in 'Pasadena Tournament'). (Throughout the patent, Cecile is misspelled as Cecil)
