PATENT OFFICE ROSE PLANT Gerard Adriaan van Rossem, Naarden, Netherlands, assignor to Jackson & Perkins Company,

Newark, N. Y.

This invention relates to a new and distinct variety of Hybrid Tea Rose plant, resulting from a cross between two well known and very attractive roses, (Charles P. Kilham x Margaret Mc- Gredy), possessing in themselves highly desirable characteristics in form and color.

The new variety is distinctively different from either of its parents and is characterized as to novelty by the attractive development of color of its blossom ranging from brilliant Carmine in the bud to Spectrum Red in the full blown flower, and the blending of the color tone of the outside petals into that of the center petals of the flower as more specifically described hereinafter.

A further feature of distinctiveness resides in the petal reflexing form of the half open fiower and the similar characteristic of the fully open flower, in which each petal curls back as it develops and exposes when fully open, the nest of aniline yellow stamens.

This new rose also possesses the very desirable habit of vigorous and compact growth, with abundance of foliage.

The following is a detail description of this new variety, the color terminology being in accordance with Ridgways Color Standard:
