ROSE PLANT Roy L. Byrum, Richmond, Ind, assignor to Joseph H. Hill Company, Richmond, Ind, a corporation of Indiana Application October 24, 1945, Serial No. 624,229

The present discovery relates to a new and distinct variety of rose plant, particularly suitable as a greenhouse forcing variety, originating as a sport of Better Times (Pl. Patent #23).

This sport was discovered by me while budding eyes on Better Times plants, and was recognized at once as wholly distinguishable from its parent variety.

1 Claim. (Cl. 47--61) By asexual methods of reproduction of the new variety and customary tests, it was determined that this sport followed most closely the growth and habits of the Briarcliff group, of which Better Times and Peters Briarcliff are typically representative. In color impression, it most nearly resembles the variety Vanity Fair (Pl. Patent #583), and thus comparison with the latter to show the distinctiveness of the sport is appropriate.

In the first place, the present variety has a stiff neck whereas that of Vanity Fair is very bending. Vanity Fair has more thorns and its buds are not as pointed as found in this sport. The primary distinguishing characteristic is the scalloped edges of the petals.

In the drawing:

Figure 1 is a view showing the bud as calyx breaks;

Figure 2 is a. view of the bud as first petal opens;

Figure 3 shows the bloom at the half-blown stage;

Figure 4 shows the full blown flower;

Figure 5 is a view of a section of a branch disclosing the arrangement, form and color of the thorns; and

Figure 6 depicts a specimen of the foliage and stipules.

Asexual reproduction of this new variety shows the foregoing characteristics come true to form and are established.

The following is a detailed description of the new variety, color terminology being in accord with Ridgways Color Standard, except where otherwise indicated to have ordinary dictionary significance:

This description of a newly opened flower Was made from a rose grown in a greenhouse in the month of April, at Richmond, Indiana:

Color-Outside petal-outside surface: Hermosa Pink, Plate 1; inside surface: Hermosa Pink, Plate 1, pencilled with Eosine Pink, Plate 1. Intermediate petal-outslde surface: Hermosa Pink, Plate 1, shaded with Eosine Pink, Plate 1; inside surface: Hermosa Pink, Plate 1, shaded with Eosine Pink, Plate 1. Inner petaloutside surface: Hermosa Pink, Plate 1, shaded with Eosine Pink, Plate 1; inside surface: Hermosa Pink, Plate 1, shaded with Eosine Pink, Plate 1.

3 This description was made from a rose that was open for three days in the month of March, at Richmond, Indiana:

Color.-Outside petal outside surface: be-

tween I-Iermosa Pink, Plate 1, and White; inside surface: between Hermosa Pink, Plate 1, and White. Inside petal-outside surface: Hermosa Pink, Plate 1; inside surface: Hermosa Pink, Plate 1.

General color efiect-Newly opened flower- Hermosa Pink, Plate 1. Three days open between Hermosa, Pink, Plate 1, and White.

I claim:

A new and distinct variety of rose plant, characterized as to novelty by the color of the blooms, stiffness of the neck bearing said blooms, pointed form of buds, lesser quantity of thorns as compared with the variety Vanity Fair which it most nearly resembles, and scalloped edges of the petals, substantially as shown and described.
